i train in some of the nasbar line of clothing. inexpensive, wears well, comfortable enough for everyday riding, fits good enough to sweat in and when you hit the deck you haven't trashed a $80 team jersey and $120 pair of pro shorts.
don't misunderstand me. by no means it high quality italian pro-team kit, but i feel some of the line is a bargain.
