I love these new Attack Air bib shorts. The bib material is very nice and soft and chamios is very comfortable. First time I rode wearing these bibs I did 100 miles without any problems. I can't attest to the durability of these yet but I'm hoping they will last awhile. I'm 5' 9', 185 lbs. and size large is very tight. If I buy another pair I'll get a XL.
