Product details
The DonJoy Reaction Knee Undersleeve Replacement is a genuine replacement undersleeve designed for use with the DonJoy Reaction Knee Brace. It is a comfort and stability accessory only — the knee brace itself is not included in this listing.
Constructed from a breathable 85% nylon and 15% spandex blend, the undersleeve sits against the skin beneath the brace shell to help reduce brace migration during activity and improve overall fit. Its close, low-profile knit is designed to work with the Reaction brace's frame and hinge system without restricting freedom of movement.
