Triathlons require a bunch of gear and Louis Garneau's TR-40 bag has room for all of it! Boasting an easy-to-access main compartment that opens wide, this spacious backpack includes multiple pockets so you can organize your equipment for each leg of the race. A ventilated, zippered pocket on the bottom stores wet garments, too. The exterior of the pack includes an expandable mesh pocket that's perfect for your helmet, a pair of bottle holders, straps to hold your pump, and elastic drawstrings for your transition mat. For carrying comfort, you'll love the cushioned ergonomic back panel, the adjustable, ventilated shoulder straps, an elastic sternum strap, and a removable waist band.
