So far, so good!

Comments On Nov 29, 2012:I have one ride with these braces and they feel and work great. They came with extension stops 0-20 in increments of 5. I am running the 15 as I am 8 weeks post acl surgery right now and dont want to bear weight past that extension point. I will update the review as I continue to use them, I chose these over Asterisks because of their simplicity. They feel slim, lightweight, strong, and I like the extension adjustments. One problem I see so far is that they dont have much protection from twist. I may modify my brace to use a strap connected to the boot for anti twist resistance. the asterisk ultra cells have this feature. These alpinestars braces dont disappoint with material quality. Overall I'm very pleased with my purchase and would recommend this brace to anyone looking for a orthopedic style brace with moderate impact protection and a slim fit. Limited features, but very comfortable and good hyperextension and sideways movement protection. I will use these for snowboarding too.

not Alpinestars quality

Comments On Aug 09, 2011:I've had these braces for almost a year. I previously rode with Asterisk braces for 4 years but wanted to try these. I use braces because I don't have an ACL anymore in my right knee. The Alpinestars have been a let down. In the first two rides, the tiny screws that hold the top strap to the brace backed out on both braces. The threaded portion is so small it's ridiculous. I used longer threaded screws to replace them and they've held in place. I had to do some grinding and taping to make it work. They migrate down your leg unlike Asterisk braces. The little snaps that hold the knee cap/patella piece in place won't stay snapped at all. Fortunately, the snaps are to big to pull through so the knee cap piece doesn't fall completely out. The padding behind the knee cap is pretty thin too. I've used the brace for skiing as well as dirt biking... Asterisk fit better and stayed place MUCH better as well as stayed together. The only thing these braces have going for them is their light weight. I don't recommend these braces.
Additional Comments On Sep 20, 2011:After posting this review I received a phone call from Alpinestars. They wanted to look at my knee braces and replace the FOR FREE. They have have made small changes in the current braces. It was a pleasure to deal with them as a company. The screws that fell out have been addressed and the top and bottom straps are wider. They do have a very simple adjustment for the flexion stops. I like how simple it is to adjust the range of motion.
Thank you Alpinestars for have continuously updating your product and for world class customer service.

Was not comfortable

Comments On Nov 28, 2010:I tried the large and x-large A-Stars B2 Left Knee brace and neither one fit right and neither one was comfortable. Finish is nice, but it is bulky in the hinge area. Beware the online sizing is not accurate. I ordered the POD MX knee brace and love how well it fits. A lot slimmer than the A-Stars B2 brace.
