Oasis 18L Hydration Pack with 2L Bladder
Here’s what we’ve heard: It’s 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 that’s a day hike, festival, or really long walk. Bonus: The color choices are dreamy.
Rugged and Ready: Built with TETON innovation, this outdoor favorite is made with durable ripstop construction for lasting function.
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 you’re out and about.
Ample Capacity: We weren’t 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).
Lifetime Warranty: Take comfort in TETON’s lifetime warranty. Our amazing customer service team is also here if you have questions or concerns.
