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

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

Frequently Asked Questions

How do I choose the right knee brace for my condition? + –

Consider the type of injury or pain you have. Mild aches might benefit from compression sleeves, while ligament tears often need a hinged brace for added stability. Unloader braces work well for arthritis, and patellar supports help with kneecap alignment. Checking each brace’s features and consulting a professional can ensure you find the best match.

Are knee braces good for osteoarthritis? + –

Yes. Unloader braces specifically shift weight away from arthritic compartments, reducing bone-on-bone friction and easing discomfort. Many people with osteoarthritis find they can walk or stand longer and with less pain when wearing an offloader brace that preserves the remaining healthy cartilage.

Should I wear a knee brace while running or exercising? + –

If you have a minor sprain, mild instability, or a manageable ligament or meniscus issue, a supportive brace with moderate compression can help prevent aggravation during workouts. For more serious injuries, talk to a healthcare professional before running, as some braces can stabilize the knee but don’t guarantee complete protection from high-impact moves.

Can I sleep in a knee brace for overnight support? + –

Many post-surgery or severe injury patients are advised to keep the knee immobilized at night. However, wearing a brace 24/7 can sometimes cause stiffness or skin irritation. If your doctor recommends it—and you feel comfortable—sleeping in a suitable brace can reduce accidental movements that worsen pain.

How do I measure my knee to ensure the best brace fit? + –

Most braces rely on measurements around the mid-patella (kneecap) and sometimes thigh and calf circumference. Use a flexible tape measure snugly—yet not too tight—around these areas. Comparing your measurements to each product’s size chart helps you select the ideal size. If you’re between sizes, opting for the larger option often prevents circulation issues and maintains comfort.
