As others have said, the straps are itchy. Sending them through the wash does help. For the extra bit of money, I'd just purchase the velocity 2.0's - better straps, more comfortable.
The material on the legs is very comfortable, not as comfortable as the jerseys but solidly constructed. The shoulder strap material, however, is very unpleasant against your skin. It’s scratchy and rough. I now understand why these were on sale and would return them if that were an option. Wyn should know better and should have learned in their own product testing how terrible the shoulder material is.
The fabric is absolutely amazing. Lightweight, stretchy and fast.
Too itchy at the shoulder straps
