Favorite shorts for DH
The Troy Lee Moto shorts are hands down my favorite short to ride for downhill, they are super durable, offer tons of protection and move well with your body. I never used the removable hip pads and think the fit is really great without them. As far as sizing, they are pretty much true to what you would wear as a street short or pair of jeans.
I have used the Fox Demo short as well, which I think are great, but I feel more protected in the Troy Lee's.
