I was going to buy a different helmet (Bell Z20) than OP from Trek and asked about return policy. The lady said 14 days to return and it cannot have been worn, unless it was just around the house for fit and sizing. So it would seem they have a diffident return policy between Bontrager or other brand products... I did not use, returned and bought a Specialized Tactic III from a different place. Reason being the Bell Z20 was a bit much bubble head and I wanted something with a small visor.
