Lyric Rosattiwrote a review of Alpinestars A-Line 2 Elbow Guards on March 20, 2017
Familiarity: I've used it once or twice and have initial impressions
The "anatomically constructed bio-foam" at the elbows is really hard and hits the boney parts during normal wear. No one's elbow anatomy is shaped like this. Other elbow pads I've owned, mostly hockey elbow pads, have relief for the boney part of your elbow and carries the load on the areas with some muscle. I'll probably modify these to have elbow relief like that if I keep using them.
Also of note, Alpinestars says right in the manual that these are for motorcycle use only and don't guarantee protection for any other activity. Also, the manual says don't submerge these in water, so my intended use (and Devin's) is definitely outside of the scope of intended use.
I would have returned these, but it's hardly worth the effort when I bought them for 22 bones. Can't recommend, even at $22.
