Does it have a crotch chamois or another form of protection (cushion) for the long rides ?
A shopper on Feb 12, 2015
BEST ANSWER: I order this for my snowboard but i missed my shippement to go snowboarding so im not sure how it is.
But I can tell it fits very comfy has Soft crotch pad
cover front to back, Thighs pad and triangle shape tail bone pad these pads r soft pad but harder than crotch pad.
As a rider my opinion.... I thing Its good for protect when u fall down wit ur bike or light impact.
I may try out heavy duty looking body armor.

What are the general sizing of these undershorts? Waist and inseam?
A shopper on Feb 26, 2012
BEST ANSWER: The general sizing for undershorts is based off of your waist measurement and is as follows.

Small - 30
Medium - 32
Large -34
Extra Large - 36

We would recommend using your underwear size
I am looking for an undershort to make me more comfortable on long rides. I am having problems finding a short without uncomfortable seams in the seat area. Is the seat area with the pad seam free? I don't mind if they have one seam right up the middle.
A shopper on Jul 8, 2015
BEST ANSWER: It is quite comfortable there. It's built like a bike short in that it has a pad through the crotch area. It is sewn in; however, the pad is "thicker" than any seam, so it's quite easy to wear.
