Breg Undersleeve Brace – Cotton or Neoprene Liner for Knee Brace Comfort and Sensitive Skin

The Breg Undersleeve Brace is designed to provide a comfortable, protective layer between your skin and functional knee brace. Ideal for those with sensitive skin or seeking improved suspension, this sleeve enhances brace performance while reducing friction and irritation. Choose the soft Cotton/Lycra blend with a closed patella for full coverage, or the 1/8” Neoprene sleeve with an open patella for greater kneecap flexibility and support. This accessory helps secure your brace in place, encourages daily compliance, and supports soft tissue containment during movement or recovery.

Sizing Guide

Pick your material: Cotton/Lycra (soft, breathable), Neoprene (cushioned, open patella), or Supplex/Lycra (lightweight stretch), all knee-length liners
Stand and note the distance your brace covers (mid-thigh to mid-calf)
For Cotton or Supplex/Lycra, choose the sleeve length that best matches this coverage
For Neoprene, all sizes are 19 inches long—select the same size as your brace (XS–2XL)
Check your measurement against the size options and select the size that meets your coverage and comfort needs.

How to Wear / Fit

Slide the undersleeve over your foot and pull it up so it fully covers the area under your knee brace
For open-patella Neoprene, align the opening over your kneecap
for closed-patella styles, center the knee under the fabric
Smooth out wrinkles so the sleeve lies flat against the skin
Apply your knee brace over the sleeve and recheck comfort while standing and walking.
