Hydrapak hydration system. I bought this out of curiosity, but I haven't had a chance to use it, so I'm decluttering. There is some dirt on the package and hose due to storage, please check the images. It is unopened, so the parts hidden by the package are unconfirmed. Also, since it is unused, the performance is not guaranteed. Please understand this beforehand. Manufacturer's description: The "Contour" is the flagship model of hydration reservoirs, packed with all the user-friendly features to achieve the best performance. It's a lightweight, compact, and sturdy hydration system. With updates like the 3D bottom, Shape-Loc™ baffle, and a hose attachment on the side of the water bottle, it provides excellent fit and performance in various backpacks for activities like mountaineering, backpacking, hiking, trail running, and adventure racing.
