Trek DraftPack Seat Pack

Trek's DraftPack Seat Pack features a thermoformed, waterproof body that holds its shape empty or full. The clamshell design, full zip and internal mesh pocket make accessing your gear a breeze. Plus the slim, ultra-light DraftPack hides behind the seat and post so it's out of the wind and won't slow you down. It also attaches to the seat rails and post quickly and easily.
