Breg Fusion XT Knee Brace

By combining a high-strength frame design with lightweight, aircraft-grade tempered aluminum, Breg Fusion XT Knee Brace withstands the rigors of contact activities. FUSION XT knee brace now features new AirTech™ innovation.

Our newest Fusion innovation, AirTech was specifically designed to improve comfort and fit. AirTech is a complete system of air mesh vents and grooved channel frame pads that increase airflow throughout the brace. The system allows cool air in and moves warm air and moisture away from the skin, improving patient comfort. The new pad technology also improves suspension, reduces pinching and helps alleviate pressure points.

Designed to significantly improve comfort and fit, AirTech is a complete system of air mesh vents and grooved channel frame pads that increase airflow throughout the brace.

Good brace, use it for basketball

good sturdy brace, doesn't really slip, i wear it with a compression pants for basketball, great brace for basketball, took me about a week to get used to the brace, but overall after a week or 2 of using the brace, you barely notice the brace is there. i have lateral meniscus tear and had ACL surgery done. i couldn't play without pain, this brace definitely took the pain away. highly recommend

Excellent knee brace for acl/pcl

After a motorcycle wreck 15 years ago,I have had seven knee surgeries and worn a brace every day, this is by far the most comfortable one I have had. In fact this is the second one like this that I have bought, the first one (and older model) lasted eight years with several strap and padding replacements before the hinges gave out. I recommend buying extra neoprene sleeves because it makes the brace stay in place much better during water sports. I would recommend this brace to anyone with ACL and PCL problems.

Just did not protect

After Tearing my right ACL in football and having it repaired i was recommended this Brace. well when returning i noticed it didnt want to stay in the spot you put it in. in several games into the season i had to take my football pants off at halftime and re-position the brace. 6 weeks into the season i was Filling my right B gap when i got to the hole i blew it up, getting hit from my left side i planted my right leg down and snap all over again. i am not able to play anymore sports now and this left me watching from the sideline my senior year. i know freak accidents happen but iv never had to re adjust a brace so much.
