I find these to be very comfortable, and the seams don't cause any chafing like some other brands I've tried. The waistband is not too thin, and they are great for erg workouts.
When I had trouble completing my online order, a friendly rep helped me complete it by phone and email. I liked the specific sizing information to help with selection.
My husband loves the MEN'S ACCEL II SOLID ROWING TROU. They fit him perfectly, and he said they are really comfortable. I bought 4 pairs for him as the price is quite reasonable.
