How Does the Brace Work?
The external webbing (or elastic exoskeleton) of the Donjoy Reaction Knee Brace dampens impact forces experienced by the knee joint and disperses this energy across the knee. This helps reduce shock targeted in a specific area. The support is also fitted with an under sleeve so you remain as comfortable as possible.
What's the Benefit of a Webbed Design?
The unique open-framework design of the Reaction Knee Brace isn't just for a sporty aesthetic, it also provides a refreshing breathability that no other knee brace can match. The webbing is designed work like a high-tech spring that boosts the power of your knees, while also allowing fresh air to cool the skin during intense physical exercise.

Is This Support Suitable for Watersports?
This support can assist with the impacts and pain associated with water sports, but if it is used in salt water, it should be rinsed with clean water after each use. It should then be dried, as some components of the brace may wear over time if left waterlogged.
Supplied with an Undersleeve
To maximise your comfort levels, the Donjoy Reaction Web Brace comes supplied with a nylon-spandex undersleeve that prevents the brace from rubbing unfavourably against your leg. Just as breathable and stretchy as the brace itself, this undersleeve provides added protection warmth and comfort without impeding movement.
