Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
Size Bought: Medium
I try and do most of my rides without wearing any sort of pack and these bib liners help me get that done.
3 pockets on the back plus the water bladder / back protector pocket along with a small pocket on the lower leg.
Chamois feels fine, and according to the size chart I should be in a Medium but I feel that might be a bit misleading. at 5'9" 175 lbs I have a 34 inch waist but felt the legs are a bit tight and the should straps could be a bit longer or more stretchy.
Once I'm out on the trail I don't notice it. My real only complaint is that I would like maybe the side back pockets to be a tick lower for easier access, I'm simply not really flexible in the arms / shoulders.
