Heres what weve heard: Its the perfect size, you can quickly bungee a helmet or coat to the back, and it carries enough water for a full day of adventure. TETON has taken its original (and extremely popular) hydration pack and made it even better. With two sizes, you can find the ideal pack to meet the demands of your next adventures, whether thats a day hike, festival, or really long walk. It's actually ambidextrous: No more being forced to reach across to your other shoulder because the Oasis features hydration ports on both the left and right sides. Simplicity and Ease: The front-zip pockets offer easy access for grab-and-go while youre out and about. Ample Capacity: We werent kidding. You can go all day with this TETON hydration pack thanks to its 2L bladder (and two bottle-holder side pockets in case you're really working hard).
