JanSport plus Nalgene equals the best hydration system. Water Tower packs meet the needs of those who put extreme demands on reservoir Technology. JanSport's Water Tower reservoirs have been massively upgraded to meet and surpass the expectations of users who demand proof of performance, and are quite frankly paranoid about cleanliness. Water Tower design provides greater water flow to your mouth. JanSport could bore you with technical descriptions of hydrostatic head pressure, but simply put they've shaped the reservoir to keep the water as high as possible throughout the drinking cycle. Nirvana mouthpiece provides 113.9% the water flow of the nearest competitor, and up to 300% of the flow of bargain brands. Ergonomic shape of the Water Tower and JanSport pack mimic the shape of the human back; it's wide where your back is flat and broad, yet narrow to hug the muscles of your spinal column
Hydro Rak and toggle. Typically as soon as you put the reservoir into your pack, the darn thing slumps to the bottom. You can beat the slum, with the Hydro Rak. The toggle installed at the top of the reservoir sleeve in JanSport packs simply slips through the Hydro Rak and your reservoir hangs high and tight. Quick Connect. Wouldnt it be cool if you didnt have to pull the drink tube out through the should straps, and then put it back, every time you filled the reservoir? The Quick Connect valve at the bottom of the Water Tower reservoir allows you to chill your reservoir in the fr4eezer without freezing the drink tube solid. Nirvana bite valve with EZ shut-off. No drips. The bite valve has a 90-degree angle to make it easier to use, and the EZ shut-off at the end of the hose prevents drips when youre not using it. Big Bore Opening. The galactic standard 63mm opening allows you to attach most water purifiers and filters directly to the reservoir for filling-anytime, anyplace.
