## Description

Composed of 100 percent latex-free 4.8 millimeter neoprene (CR) with exclusive binding, straps and cover fabric. Available in sizes small, medium, large, extra large and double extra large. To find your correct size measure the knee to be protected (you likely figured that). Stand and bend your leg just less than 45 degrees, measure around the largest part of knee, directly over the patella (kneecap).

Review: Comfortable and supportive - Great brace, my son wears for football. Says it’s the best knee brace he has had. We have tried dozens
Review: Nice fit, reasonable price, feels good & seems to help - I got this 2 strap version to use at the gym and while working out in the yard. Just rec'd and made one trip to the gym. I'll update / edit later if my opinion changes. The brace did not slip down at all while doing elliptical at the gym. The straps kept it in place, unlike my older strapless neoprene sleeve. The side 'springs' seem to add some stability to this as well. I have a bulkier / sturdier / expensive Corflex hinged braced from the VA and this is almost as good for support or pain relief. This less costly ($23) one from McDavid will be great if it lasts 6-12 months of rugged wear. I did not feel restricted while wearing at the gym. I think this is the same as the Shock Doctor brand. The brace did have a rubbery odor when I unpackaged it. I hosed it down with Lysol and its fine now. I measured approx 17-17.5 / XL and its pretty snug. I may opt for XXL when I have to replace this one. I would think one could order up and use the straps to tighten it without any trouble.

### ⭐⭐⭐⭐ Tricky in between sizes
*by G***C on November 16, 2014*

This got complicated. I first ordered the Large (15 - 17") as people said they fit tight. My knee is 15 1/4" so that seemed to make sense as the medium was rated 14-15. It fits OK, but I need to crank the straps over pretty tight & then I have a tuck on the top of my thigh, which hasn't been a bother so far. After a few uses I found that I need to crank it tighter & the Velcro is now going over the female side & pulling away at the stitching on the bottom, which will make it wear out sooner I guess. So, I ordered a medium just to see what it was like & wow was it tight! I could not get it up all the way so I sent it back (hurray Prime). To me the sizes should be 12-14, 14-16, 16-18, 18 - 20, etc. but I guess they have reasons for making them the way they do. For the money however it is a great support & way better than the Ortho one I had before.
