Breathable Lightweight Hydration Backpack

Designed for cycling, running, hiking and cross-country marathons, this backpack features breathable mesh back panels and lightweight construction. Dimensions: 45 x 28 x 15 cm; weight: 420 g; hydration bladder capacity: 2 L (included). Made from durable, weather-resistant nylon with abrasion-resistant base and water-repellent zippers. Ergonomic adjustable shoulder and sternum straps ensure secure, custom fit across varied torso lengths and shoulder widths. Integrated hydration sleeve accommodates standard 2L bladders with insulated drinking tube routing and quick-access bite valve. The breathable mesh ventilation system actively disperses heat and moisture during sustained effort — whether climbing steep trails, pacing long runs or maintaining high cadence on road or gravel. Hydration access is seamless: the tube routes cleanly over the shoulder and remains within easy reach without breaking stride or balance. All components — from stitching to zipper pulls — are tested for repeated use in dynamic outdoor conditions, including light rain, UV exposure and trail abrasion. Ideal for full-day hikes, multi-hour training rides, trail races and urban commutes where airflow, weight distribution and on-the-move hydration matter most. Works equally well as a standalone running vest alternative when paired with compatible waist straps (sold separately).
