Limitation: water bottle not included, and capacity depends on the bottle you attach.
Buying Guide
What capacity should you choose? For longer runs or cycling, a 2L bladder often provides enough fluid without frequent refills. Shorter runs may benefit from 1.5L or belt options to reduce weight. How should you fit it? A snug, bounce-free fit minimizes chafing; look for adjustable shoulder straps and a stable waist belt. What material matters? Durable nylon with a breathable back panel improves comfort in heat. Hydration systems: consider leakproof valves, bite valves, and easy cleaning access. Is storage important? Pockets for gels, keys, and phones enhance convenience during training.
