Why Do I Need an Open Patella / Open Back Knee Sleeve?

This neoprene knee sleeve is one of BraceAbility’s most popular knee braces with an opening around your patella (kneecap) and popliteal (behind your kneecap). BraceAbility’s open patella neoprene knee support was designed to protect your knee from future injuries, alleviate your knee pain, and provide comfortable support to your knees.

This knee sleeve can help treat many causes of knee pain and knee conditions including:

6 Reasons Why People Love This Neoprene Knee Sleeve

  1. It’s simple

This hassle-free slip-on recovery knee sleeve can be worn interchangeably on your right or left knee. There are no adjustable straps, closures, or fastens to deal with, making application quick and simple for athletes and non-athletes alike.

  1. The open patella and open popliteal design prevents bunching

If you find solid neoprene knee supports or ACE bandages sweaty and uncomfortable, this brace is definitely a better fit for you. Although full coverage knee sleeves provide a little extra support, they tend to bunch behind your knee joint and slide down during physical activities and sports. This open front/back neoprene knee sleeve is a more breathable option and stays put without bunching, giving your knees the support they really need.

  1. Great for athletes

The extra support provided by this knee brace allows athletes suffering from sports-related injuries to continue their normal fitness routine. However, powerlifters and bodybuilders often favor BraceAbility’s closed patella knee sleeve for its extra support.

  1. Made from 3/16” thick premium-grade neoprene

This discreet black knee sleeve is 13” long and 3/16” thick, making it not too flashy and flat enough to fit under ordinary pants, such as jeans, but still thick enough to provide adequate compression and support.

  1. Water resistant

This water-resistant knee brace is perfect for swimming, a great exercise for people trying to lose weight and much easier on your knees than running if you have knee problems.

  1. Reduces swelling and promotes healing

This neoprene material provides warmth and moderate elastic compression to your sore knee, which reduces swelling and encourages blood flow to speed up your healing process.

Is This Black Neoprene Knee Sleeve Waterproof?

Similar to the wetsuits scuba divers wear, this open patellar knee sleeve is unique because it is made out of premium-grade 3/16” thick neoprene, which is water-resistant. Meaning, this neoprene knee sleeve able to resist the penetration of water to some degree but not entirely.

If you do wear this knee sleeve when you are sweating profusely, showering, or for a swim, it is important to lay this knee sleeve flat to dry out completely before using it again for swimming, rowing, sailing, waterskiing, wakeboarding or surfing, for example.

Interim opinion

Order, shipment and item received quickly, Your chart was not correct. I measured for knee supports as outlined on your website. Supports did not fit and were not close. I returned supports per your email instructions. At this time, I am waiting to receive new supports. I am reserving my opinion until new supports are received.

Running With the Neoprene Sleeve

The sleeve did provide stability of patella-femoral movement during jogging without slipping and was very helpful in that regard; my only problem was that the back of the sleeve pressed against the upper popliteal fossa soft tissues and caused post run tenderness in that area. Some soft padding in that area would likely alleviate that problem.

The Best Knee Support for Bad Knees

I had a maniscus tear in my knee. Even with surgery and therapy, the knee was never the same. I love to hike along the Colorado Plateau. When I was at Bryce Canyon NP, I purchased the knee brace at the General Store. It was fantastic! I purchased a second one for my other knee before leaving Bryce. The support was exactly what I needed and allowed me to continue my hiking during my trip and experience the Colorado Plateau many gorgeous 'out of the way places'. I never would have been able to hike to 'The Wave,' had it not been for the knee supports. Thank you for this wonderful product. I am purchasing some knee braces for Xmas presents.

Works great.

Have bought from them before and the brace worked great. Got another one for the other knee. Have bone on bone and it helps between shots.

Product and telephone assistance

We ordered two knee sleeves. The first being too small although the measurements matched the size. The phone rep was vary helpful in returning it and shipping the next larger size. Along with feedback regarding a query I made about un-streched size being perhaps too small. She obtained the response came from your design folks. And was prompt to call back when it was available. An outstanding ph0ne rep. We are amateurs groping for a pain solution without recommendations from the local medical staff. So "non-success"" is not, in our opinion but perhaps we're not getting the correct brace. That remains a work in progress at this end. Editorial note. Responding to you email nudge, there is a comment at the bottom which states "Having trouble with this form? Submit online" - and provides a link - which takes me to exactly the identical form. Duh. I had wanted to send an attachment cartoon to the very professional phone rep, but cannot find any mechanism to accomplish that task. Amazing phone support and return policy. Thank you.
