Bontrager's Trek Co-op Jersey is the official top of the team. It features lightweight, breathable and quick-drying fabric with mesh panels at the underarms and back so you stay cool and dry. The unibody design eliminates shoulder seams for custom comfort, while a full invisible zipper offers ample ventilation and easy on/off. Three rear pockets and silicone grippers at the waist and arms are nice finishing details you'll notice and appreciate on every ride. It even has a radio pocket sewn to the inside of the center back stash pocket.
