When you're focused on racking up long miles on the trail, the last thing you need is a heavy, bulky backpack. That's why we developed the Summit Run Race Day Vest. It features a generous 8 litres of space for storing gels, a shell layer and other race day essentials without weighing you down. There are two custom 500 ml soft flasks included that can be attached to the bottle pockets via a leash system. This enables quick re-loading, even when they're empty, allowing you to stay hydrated on the go. The front fastening system is fuss-free and easy to adjust while you run. And the durable ripstop fabric is engineered with FlashDry™ technology, which wicks away sweat and moisture to keep you cool and dry.
