Stay light, move freely, and keep hydration within easy reach. The MIER Running Hydration Vest is built for runners, cyclists, hikers, and endurance athletes who need reliable storage without extra bulk. Made from lightweight breathable neoprene, this vest delivers a secure bounce-free fit while keeping your essentials organized and accessible on the move.

The included 500ml BPA-free soft flask features an easy bite valve for quick hydration during long runs, races, hikes, or rides. As you drink, the flask compresses to reduce sloshing and movement, helping you stay focused mile after mile.

Designed with multiple storage pockets across the front and back, this hydration running vest gives you space for your phone, keys, gels, earbuds, towels, and race-day essentials without feeling bulky. Adjustable chest and side straps provide a personalized fit for both men and women, while reflective details improve visibility during early morning or nighttime workouts.

Whether you're training for a marathon, tackling trails, cycling through the city, or heading to a music festival, this lightweight hydration backpack is made to move with you comfortably.
