Sobre nuestros productos

Nuestros covers protésicos son accesorios protectores y estéticos para las prótesis que devuelven la forma anatómica y la simetría del paciente. Al mismo tiempo, ofrecen una forma de expresar la personalidad y el estilo únicos de cada uno con diferentes niveles de personalización. Fabricados con las últimas tecnologías de impresión 3D, nuestros covers están disponibles para la mayoría de las prótesis de miembro inferior y componentes protésicos del mercado (transtibiales, transfemorales, bilaterales, de osteointegración, etc.).

Nuestros covers son fáciles de poner y quitar, permitiendo un acceso fácil a los componentes protésicos, proporcionando una opción más limpia e higiénica que las fundas de silicona o espuma. Los covers también son una solución más sostenible, ya que nuestro proceso de fabricación es de residuo cero.

At UNYQ, we offer four types of prosthetic covers to meet the unique needs of our users:

  • CustomFit are our signature personalized covers, available for TF and TT prosthesis, that comes in two versions: Firm, for enhanced durability and protection, and Flex, designed for more active lifestyles—both fully customizable in design and anatomy. Each cover is individually designed according to the user's specific anatomy and prosthesis. 
  • OneFit is our complete solution that covers the entire prosthesis, from the socket to the ankle, providing full protection with a functional joint. Available for TF prosthesis (specific knees).
  • QuickFit is a semi-custom option for TF prosthesis, ready to wear in just one fitting, that comes in 2 sizes that can be adjusted in length in the clinic.
  • KneeFit offers a specialized cover for the knee joint (TF prosthesis, specific knees) combining protection and a natural look in one piece.

Los covers UNYQ son fáciles de identificar gracias al logotipo de la marca grabado en la parte superior de cada cover, y a un número de serie individual grabado en el interior. Esto facilita el reconocimiento de nuestro producto y simplifica el volver a realizar un pedido para el mismo usuario. 

  • Protection:  Shields your prosthetic components from daily wear and impact. While the cover itself may be damaged, it protects the internal prosthetic parts, ensuring they remain safe.
  • Easy and perfect fit:  Our products are designed for a perfect fit, ensuring ease of use and all-day comfort. Easily fitted in just a few seconds, they allow quick access to the prosthetic components.
  • Durability:  Made with high-quality materials for long-lasting performance.
  • Anatomy and style:  Enhances anatomy and offers a more natural look, whether it's our standard or custom covers, which provide a wide range of designs and colors to express your individuality.
  • Hygiene:  Smooth, water-resistant surfaces that are easy to clean and maintain, helping to keep the prosthetic components optimally hygienic.
  • Ligthweigth and waterproof:  With varying weight depending on the product and the user’s anatomy, our covers remain lightweight and are also water-resistant (this does not make the prosthetic components themselves waterproof).


Our prosthetic covers are waterproof, and can be used in both saltwater and freshwater. Splashes cause no damage to cover. We recommend cleaning the cover with fresh water and thoroughly drying it after use in water to prevent oxidation of metal parts.  Note: Please make sure that your prosthetic components are also waterproof, our covers don't protect prosthetic components from water.

UNYQ covers come with a 1 year warranty for material defects when used in moderate-impact activities such as walking, bathing, cycling, golf, and dancing. Please note that damage resulting from situations such as hitting the cover or dropping it on the floor is not covered by this warranty. UNYQ covers are not recommended for use during high-impact sports, and we advise removing the cover when engaging in such activities or if kneeling on a hard surface. Additionally, paint may become damaged if the cover is hit. Painting is excluded from warranty.

For our customized products, each cover is uniquely designed to fit each prosthesis and create symmetry with the sound limb. UNYQ provides a preview of the finished product free of charge; therefore, returns due to shape, design, or volume disagreements after the product has been printed will not be accepted. If you or your patient have special requirements, please contact our Customer Support Team to explore available options.

We highly recommend reviewing our technical guides in the Support & Resources Center for a complete understanding of how our covers integrate with different prostheses. For inquiries regarding repairs outside of the warranty, please reach out to our Customer Support Team for more details.


CustomFit Covers

Los covers UNYQ CustomFit son covers protésicos personalizados para amputados de miembros inferiores, disponibles tanto para amputados por transfemorales (AK/TF) como transtibiales (BK/TT). Ofrecen un nuevo nivel de protección y personalización para tu prótesis. El resultado final es un cover único y hecho a medida que se adapta perfectamente a cada usuario, muestra su personalidad y protege su prótesis. Tras la impresión, cada cover se pule y pinta a mano con un acabado de alta calidad para garantizar su durabilidad. Los covers CustomFit pueden comprarse de forma cómoda y fácil a través de tu clínica. Sólo es necesario tomar medidas y hacer fotos de tu prótesis y pierna para hacer el pedido. 

Flex and Firm are two distinct materials we use to create durable and lightweight covers. Firm is our classic material made from polyamide (PA12), offering both durability and style. In contrast, Flex is crafted from a more rubber-like material (TPU), designed to withstand greater manipulation and flexibility. We recommend Flex for individuals with a more active lifestyle, as it provides enhanced durability.

CustomFit Firm covers are available for both transfemoral and transtibial amputees and are fully customizable. They are made from our signature Firm material and come in over 20 designs and more than 40 colors, available in both matte and glossy finishes. For further personalization, depending on the model you select, it is possible to add an engraving or a vinyl sticker to your cover, as well as an additional knee protector for those who frequently kneel. To ensure an easy and secure fit, we offer a choice of attachments, including magnets & fast-clamp or screws & c-clamp for added security.

CustomFit Flex covers are fully customized to your anatomy, available for both transfemoral and transtibial amputees. They come in more than 10 designs, in the majority of colors from our chart. For further personalization, you can add an engraving to some of our designs, as well as choose between two attachment types: magnets & fast-clamp or screws & c-clamp for added security.

Nuestros covers CustomFit se componen de dos partes (delantera y trasera) y ofrecemos dos sistemas de fijación diferentes:

  • Imanes + Fast-Clamp: la parte delantera se fija al tubo de la prótesis con nuestro sencillo sistema rápido fast-clamp, y la parte trasera se fija a la parte delantera mediante imanes fuertes y seguros. Esta solución permite un fácil acceso a los componentes de la prótesis, por lo que es fácil limpiarlos, sin necesidad de quitarse del todo el cover. Recomendamos esta fijación para usuarios con rodillas electrónicas, ya que es más fácil cargarlas.
  • C-Clamp + Screws:  a C-Clamp system securely attach the front part to the pylon, while the back part is also screwed to the front. We recommend this option for more active users, as it provides added security. This setup is also beneficial for those who frequently engage in water activities, as it helps prevent pressure from dislodging the back part of the cover. It’s also ideal for individuals who often wear boots that may exert pressure on the back of the cover, ensuring a reliable and secure fit.

Cada cover CustomFit está diseñado específicamente para la anatomía y la prótesis de cada usuario, teniendo en cuenta sus componentes protésicos, su combinación única y su alineación. Por lo tanto, nuestros covers pueden no ajustar correctamente si cambias alguno de los componentes de la prótesis, o la alineación. Por favor, asegúrate de que la prótesis y la alineación son las finales antes de tomar las fotos y las medidas para pedir un cover. Si vas a cambiar alguno de tus componentes protésicos, o incluso la alineación de tu prótesis, te recomendamos que esperes hasta tener tu configuración final y te sienta cómodo con ella antes de pedir tu cover UNYQ.

Si tienes requisitos especiales, ponte en contacto con nosotros para conocer las opciones de diseño y cómo nuestros covers podrían adaptarse a tu prótesis en particular. Actualmente ofrecemos covers para amputados transfemorales, transtibiales, oseointegrados, etc., puedes contactar con tu clínica, o con nuestros equipo de atención al cliente, y estaremos encantados de informarte y guiarte en tu proceso de selección. 

CustomFit covers can be designed for transfemoral and transtibial prostheses, accommodating most prosthetic components on the market. Since each cover is tailored to the user's specific prosthesis, we ensure easy access to buttons, chargers, and other essential features, as well as adapting the cover to the shape of the prosthetic components.

We also work with osseointegrated prostheses, both above and below the knee. In this specific case, we require the prosthesis and leg to be scanned using structured light scanning technology to effectively adapt our covers.


Covers QuickFit

QuickFit covers are the standard solution in our product range. Created in close collaboration with leading manufacturers, QuickFit is the perfect introduction to the UNYQ product family, ideal for first-time users and those looking for accessible and immediate protection for their prosthesis while enjoying a standard anatomy and classic design.

Currently, it is available for transfemoral prostheses in Firm material for selected knees. QuickFit covers are delivered within two weeks and can be stocked in the clinic, providing an excellent solution in a single appointment.

They come in two sizes (S, L) and do not require photos or measurements of the prosthesis; the prosthetist only needs to adjust the length of the cover to fit the individual user.

QuickFit covers are currently available in our classic U design, in five colors (black, gray, white, blue, and skin tones) with a satin finish, for some of the most commonly used prosthetic knees on the market. They come in two sizes (S, L), and the length can be easily adapted in the clinic. We are continuously adding more knee options to our QuickFit offerings; please check our website or catalogs for updates.

In our QuickFit covers, the inner part is specifically designed to perfectly fit the prosthetic knee, just attaching the front part of the cover to the prosthesis with a C-Clamp with screws to ensure a strong fixation. Additionally, we use neodymium magnets to secure the front and back of the cover, allowing for quick access to the prosthesis when needed.

Cada modelo QuickFit está diseñado específicamente para una rodilla protésica en particular, es poco probable que se adapten a una rodilla para la que no fueron diseñados.

Our QuickFit covers are standard products, and each model has been designed in a single material based on the characteristics of each knee to ensure a perfect fit and optimal performance, as they must fit precisely to each prosthetic leg with that knee. Therefore, they cannot be ordered in a different material than the one offered.

If you require a cover in a different material, you can choose from the CustomFit line.


Users: How to place your order?

Our products can be ordered through our partner prosthetic clinics that are trained in our digital process and fitting. To order a cover, start by scheduling an appointment with your clinician. If you are looking for a customized cover from the CustomFit line, it will be necessary to take measurements of your prosthesis and sound leg, as well as pictures of both. If you are interested in a QuickFit cover, no measurements or pictures are necessary; your prosthetist will adapt the length to your prosthesis in the clinic.

If your clinic is still not on the list, just ask them to contact us aquíy estaremos encantados de formarles para que sepan cómo pedir tu cover UNYQ.

Muchas compañías de seguros médicos de todo el mundo reembolsan total o parcialmente nuestros covers protésicos. Como cada país, región y seguro funciona de forma diferente, la mejor opción es comprobar con tu clínica los distintos precios y opciones de reembolso que se ajustan a tu caso.

If you already have a CustomFit or a OneFit UNYQ cover and there have been no changes to your prosthetic or its components, you can easily reorder by providing your clinic with the serial number engraved inside your cover. Simply indicate your design choices, and we will replicate the same shape of your current cover in a new style!

Sin embargo, si has tenido algún cambio en su prótesis o en tus componentes (incluida la alineación), te recomendamos encarecidamente que primero conciertes una cita con tu técnico para volver a tomar las fotos y medidas necesarias para asegurarnos de que tu nuevo cover ajustará perfectamente en tu prótesis. Incluso un ligero cambio puede dar lugar a un ajuste inadecuado entre el cover y su prótesis. 

If you want to reorder a QuickFit  or a KneeFit cover, we don’t need to know the previous serial number—only your current prosthetic knee. 


Estos son los plazos medios de entrega de nuestras colecciones:

  • CustomFit:  3 weeks from receiving the correct measurements/pictures
  • OneFit: 3-4 weeks from receiving the correct scanning.
  • QuickFit: 14 business days from reception of the order. They can be stocked in clinics.
  • KneeFit: 14 business days from reception of the order. They can be stocked in clinics.

For the custom covers (CustomFit and OneFit), we send a preview of each personalized design to the prosthetist to check the shape and volume of the final product before the printing process. Any extra delay in confirming this preview could affect the final delivery time.

We have various options to help you promote UNYQ products in your clinic. Please contact your primary UNYQ representative or reach out to our Customer Support team to learn more about current promotions and available programs.

If your patient currently has a CustomFit or OneFit cover and there has been no change to the prosthetic, its components, or alignment, simply provide us with the serial number engraved inside their current cover along with their design choices. We will replicate the same shape and volume but with their new design. If any aspect of the prosthesis has changed, you will need to retake the measurements and pictures to ensure a proper fit for the new prosthetic combination.

If your patient wants to order a QuickFit or KneeFit cover, choose a knee and color, and once delivered, adapt the length at the clinic.


Our CustomFit covers require specific data from the patient to customize them for each anatomy and prosthetic component. You can obtain this data in several ways:

  1. Through our free UNYQ App (currently available for iOS), which guides you through the configuration process of the cover (designs, colors, etc.) and assists during the measuring process. You will easily take pictures and measurements through the app, and once you finish placing your order, all the data will be automatically sent to our system.
  2. Through our Online Shop, which allows you to select product specifics and upload photos taken separately using a camera or any smartphone, along with the measurements or 3D scanning files.
  3. If you are unable to use either of these methods, you can simply fill out our Order Form and send us the photos, measurements, or 3D scanning file by email at orders@unyq.com. You will find the Order Form and instructions for measuring/scanning in our Support & Resources Center.

Note: For osseointegrated patients, a scan is always required.

You will find all the recommendations and instructions in our guides, but here are some of the 3D scanners we recommend if you choose that option:

  • Escáner Einstar
  • Escáneres manuales Shining 3D Einscan Pro Series
  • Escáneres manuales de luz estructurada de Artec
  • Escáneres manuales Creaform


Our OneFit covers require a 3D scanning from the patient to customize them for each anatomy and prosthesis. Once you scan the prosthesis and sound leg, you can process your order in two ways:

  1. Through our Online Shop, which allows you to select product specifics and upload the scanning files. We recommend this option so you can have access later to your order details and status.
  2. If you are unable to use our Online shop, you can simply fill out our Order Form and send us the 3D scanning file by email at orders@unyq.com. You will find the Order Form and instructions for scanning in our Support & Resources Center.

Here are some of the 3D scanners we recommend:

  • Escáner Einstar
  • Escáneres manuales Shining 3D Einscan Pro Series
  • Escáneres manuales de luz estructurada de Artec
  • Escáneres manuales Creaform


Ordering our semi-custom QuickFit covers or KneeFit covers does not require taking measurements, pictures, or scanning the patient. You just need to choose the prosthetic knee of your patient and the selected color, and, in the case of QuickFit, pick the size that fits best with their anatomy, which you will adjust in length in the clinic. 

Both products can be ordered through our online shop (for clinics only) or by directly sending our Order Form along with the information about the chosen knee, color, and size to our Customer Support team.
