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