Measure the circumference of your thigh 4 inches (10 cm) above the middle of your knee cap. Continue to 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 the safe side.
| SIZE | CIRCUMFERENCE (cm) |
| Small | 34-37 |
| Medium | 36-39 |
| Large | 38-42 |
| X-Large | 41-46 |
| 2X-Large | 45-50 |
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.
The Alps Reinforced Flex Sleeve (RFX) by Alps South is expertly designed for nearly all below-knee prosthetic users and activity levels, offering an ideal combination of comfort, durability, and performance. Alps has developed a proprietary white gel formula that provides the comfort of their original gel with the enhanced durability of their HD Gel. This advanced material ensures excellent adhesion to your thigh, offering stability and security for high-activity users who require maximum control and comfort. With the same trusted features as their popular SFX version, this Reinforced Flex Sleeve delivers superior performance for those who push their limits.
Engineered with a premium knitted outer fabric, the RFX Sleeve promotes flexible knee movement and a full range of motion, particularly through its horizontal stretch. This flexibility makes it an excellent choice for users who enjoy activities like cycling or yoga. Its secure suspension creates a reliable seal with the skin, maintaining a strong hold without restricting circulation. Compatible with both suction and vacuum systems, this below-the-knee sleeve is easy to install and clean, especially when using Amputee Essentials Prosthetic Cleanser. Designed for durability and freedom of movement, the Alps Reinforced Flex Sleeve is a top-tier solution for active prosthetic users.
Installing your Alps Reinforced Flex Sleeve is easier than most sleeves. Insert the Reinforced 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 Reinforced Flex sleeve onto your thigh.
