Augustine C.wrote a review of Six Six One Riot Elbow Guards on July 21, 2013
Familiarity: I've used it several times
I would recommend buying other designs or 1 size larger from the fitment chart.
My elbows had abrasion marks from the first right as it was tight. But the padding is great which is why I guess we need to trade some comfort for safety.
However, I tried a friend's g-form and boy was it comfortable but am unsure of the protection as itwas not as thick as the 661,
