ALPS Mountaineering has introduced the Reservoir 3.0 hydration bladder. The Reservoir 3.0 features an anti-microbial IonPure treatment that helps inhibit the growth of bacteria and mold, keeping the hydration system fresher between uses. Its three-liter capacity assures an ample supply, while the slim-line design mitigates unbalanced carry or unwanted sloshing when carrying less volume.

With BPA and PVC-free construction, the ALPS 3.0 features a quick-connect insulated drink tube that minimizes leaking, guards against freezing in frigid temperatures and offers 360-degrees of intuitive custom-mounting to shoulder straps. An oversized, threaded and sealed access port allows for swift, efficient fill and cleaning.
