Media Highlights

"Hydrapak reservoirs are becoming the gold standard for most hydration packs, for two good reasons: 1) they're super durable, and 2) they turn completely inside out, making cleaning and drying a breeze." -Ultrarunning Magazine

"Most importantly, though, the reservoir is nearly indestructible - you simply cannot pop the thing.  We stomped on a full reservoir, threw it around the testing area/garage, and stacked 200 pounds of weight plates on it, with no visible damage.  It'll probably outlive you." Active Junky
