HydraPak Contour

The HydraPak Contour is an ultralight TPU hydration reservoir built for carrying inside a pack on both running and multi-day trekking trips. Its defining feature is the Shape-Loc™ baffle system, which keeps the water spread into a flat, low-profile shape even when filled to its full 3-liter capacity — this lets the bladder conform to a pack's back panel better than an unstructured "balloon" reservoir. At 155 g the weight is typical for a reservoir of this capacity rather than exceptionally light, reflecting the added structure and durable build. The Comet bite valve and Plug-N-Play quick-disconnect hose let you manage hydration one-handed while walking or running, without pulling the reservoir out of the pack. For cleaning, the whole bladder reverses inside-out and is dishwasher-safe — a real advantage over reservoirs that are awkward to clean and prone to mold. The material is BPA- and PVC-free and food-grade certified. According to the manufacturer it's compatible with filtration kits, useful for hikers who want to combine hydration with in-field water treatment.
