acl donjoy knee brace

Most listings show a lace-up closure plus adjustable straps (typically thigh and calf) or a four-strap design, allowing a customizable, secure fit.

Product bullet details list care as hand wash.

Descriptions highlight perforated neoprene or Drytex breathable fabric, breathable mesh, anti-migration technology to reduce slippage, and easy-grip pull tabs for on/off.

Listings reference use during exercise and sports play (including non-contact sports), for daily activities, and for post-injury recovery or performance support.

Many models use bilateral polycentric hinges for joint stabilization; some also include dampening hinges that limit hyperextension and improve joint mechanics.

Materials listed include perforated neoprene, Drytex breathable fabric (an alternative to neoprene), textiles containing about 45% nylon, and rubber components.

Dampening hinges are described as engaging at about 145° and coming to a full stop around 170°, preventing hyperextension.

One bundle explicitly includes a reusable 11 x 14-inch gel ice pack alongside the knee brace.
