"NOT RATED FOR IMPACT" Said right on the packaging. Now I see the fine print under Elbow Flow. It might be slightly better than cutting the toe off an old sock and sliding that over your elbow.

I purchased recently and after first use the threads started coming loose on one arm. Unfortunately raceface didn't back up the product and offered a coupon instead of replacing item. The website I purchased from planet cyclery couldn't find invoice

The are light and breathable and stayed in place no slipping down.

I won't recommend this elbow protections for anything more serious, because it's just thin mesh layer of mesh and a bit of foam. Despite this they are very comfortable and are better then nothing. I wish it would have at least a bit more protective layer so it won't be totally useless

I love it
