How to measure alps superior sleeve.

STEP 2: Find your size

Take your thigh circumference and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side.

Small 25-30 cm
Medium 31-34 cm
Medium Plus 35-37 cm
Large 38-40 cm
X-Large 41-45 cm

When measuring your thigh, pay special attention to how tight you take your measurement. It's best to pull the ends of your tape measure somewhat tight and then release. Your goal is to find a middle ground of how much tension you should apply to your measuring tape. Too tight and too loose will both result in a poorly fitting prosthetic sleeve.

Alps Superior Suspension Sleeve Description

The Alps Superior Sleeve (SFB) by Alps South was designed for all prosthesis users regardless of activity level.  The main objective of this sleeve is to provide a thin and less bulky sleeve, while still maintaining reliable suspension. The Alps team engineered the Superior Sleeve with their high density gel (HD) formula to better match the firm texture and feel of silicone, while still retaining the comfort of gel. A firmer gel translates into greater stability and control while participating in high activity events. The Superior Sleeve is suggested for those amputees that currently wear a silicone sleeve similar to Ossur's Iceross Sleeve.


  • Designed for moderate to highly active prosthetic users
  • 2mm thin uniform profile for reduced bulk
  • Creates a secure seal using a thinner profile
  • Exceptional comfort and range of motion
  • High performance fabric provides long term wear

  • Works for all activity levels
  • Excellent range of motion and easy knee flexion
  • HD Gel offers similar firm feel as silicone for superior control of your prosthesis
  • Latex free and hypoallergenic
  • Available in black color
  • Made in USA
  • Sold individually in polybag

Suggested Use

To keep up with activity prosthetic users, the Alps team added a durable fabric that prevents excessive vertical stretch and maximizes durability. Horizontal stretch is not limited and permits complete freedom of movement, making this a great contender for anyone who loves cycling or yoga.

The Superior 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 Otto Bock Derma Clean. This below-the-knee prosthetic sleeve offers the perfect blend of high performance and durability.

How-to Install

Installing your Superior Sleeve (SFB) is easier than most sleeves. Insert the SFB 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 Superior Sleeve onto your thigh.
