content: I've been riding bicycles and motorcycles for the past 40 years, wearing all sorts of helmets. Just recently got into inline skating and bought my first ProTec helmet with the skates.Apparently, someone at ProTec forgot that (1) helmets get HOT, (2) people SWEAT, and (3) the glue holding the lining and the padding and the helmet together needs to be WATERPROOF.Any store selling these helmets needs to have their HR manager write up the irresponsible buyers who would put this piece of garbage in their inventory. Yes, it's that bad. If you buy this thing, be prepared to find some nice waterproof glue and reassemble your helmet when it starts coming apart. And it WILL come apart. Unless you're an alien with no sweat glands.
