The Alps Flex Sleeve (SFX) by Alps South was built for moderate users to weekend warriors. The Alps team incorporated their (HD) hight density gel formula into the Flex Sleeve to better match the firm texture and feel of silicone, while still retaining the "gel comfort".  A firmer gel translates into greater stability and control while participating in high activity events like walking fast or sports. Users will feel an improved firmness and grip over non-HD gel bk sleeves. The Flex Sleeve is suggested for those amputees that currently wear a silicone sleeve similar to Ossur's Iceross Sleeve.

To keep up with active prosthetic users, the Alps team added a seamless, highly flexible outer fabric that promotes easier knee movement. Horizontal stretch is not limited and enables complete freedom of movement, making this a great contender for anyone who loves cycling or yoga.

The Flex Sleeve creates secure suspension by sealing with the skin without compromising circulation. This below knee sleeve is approved for use with either suction or vacuum systems (includes a pump). Installation is a breeze and cleaning is easy with Amputee Essentials Prosthetic Cleanser. This below-the-knee prosthetic sleeve offers the perfect blend of high performance and durability.


The Alps Flex Sleeve uses a High Density (HD) Gel to maintain its place for tight and confident suspension.

Directions for Use

Installing your Alps Flex Sleeve is easier than most sleeves. Insert the Flex Sleeve so that the inside is facing out and roll the sleeve up onto the socket.  Begin rolling and working the reflected lower half of your sleeve over your socket, until it's full reflected over your prosthetic socket. Once your sleeve is fully installed, begin rolling your sleeve from the top down to a level below your socket's trimelines.  When you're done it should look like a floating tube or a donut around your socket. Now your prosthetic leg is ready for you to place your residual limb inside and begin rolling your sleeve upward. Place your residual limb inside the socket and roll your Flex sleeve onto your thigh.

Care Instructions

Daily: Be sure to clean the Alps Flex Sleeve on a daily basis with a light washcloth and neutral/pH-balanced soap, Amputee Essentials Prosthetic Cleanser and Ottobock Derma Clean are especially made for this purpose. Do not scrub or rub the gel during washing, this can damage the gel. Rinse well because soap residue can cause skin issues. Make sure your Alps sleeve is completely dry before using.

Weekly: Place a small amount of rubbing alcohol on a soft, clean cloth. Do not soak the Flex Sleeve in alcohol. Wipe the sleeve with a the cloth thoroughly, wipe dry with a towel. To remove a stain on the fabric side, use a cloth dampened in nail polish remover and rub until clean. Do NOT soak in nail polish or you will dissolve the gel!
