These things suck so bad anybody who likes them has never taken a hard fall! I got them for Christmas, used them for a season, and gave them away the first chance I got.
The material is comfy but it's hard to make a useful protective device that also hides under a layer of clothing. There's a reason that helmets are big and bulky, they are made to be effective. These shorts are made simply to look cool and ease your mom's worrysom thoughts.
Save your money and try not to fall on your tail bone cause thats the only reason you are contemplaiting this purchase. THESE SHORTS DONT WORK
