ABOUT OUR ROOTS AND MISSION
In the heartland of Oregon, where the scent of pine mingles with the spirit of untamed rivers, our story is woven into the fabric of the Pacific Northwest. Born from a love for the wild and an obligation to preservation, Mazama Designs emerged against the backdrop of Mount Mazama, the once volcano that now holds one of the world’s deepest and cleanest bodies of water: Crater Lake.
Our Mission’s not a mission, it’s a ride. Where hydration and exploration collide. Our Mission is not a mission, it’s a wild expedition. No days off, that means no intermission. Explore what you want to explore. You’re free! You don’t need permission.
Trailflow: Tailored for the minimalist adventurer, the Trailflow hydration reservoir features the new VYPR angled multi-flow bite valve for easy drinking on the move. The attached bite valve cover keeps your bite valve free of trail dust. The VYPR Bite Valve boasts a detachable mouthpiece enabling easy connection to Mazama’s Aqua Shield Water Filtration System (or other compatible filtration kits) allowing you to fill your reservoir with clean, safe, filtered water from outdoor sources.
Versatile Hydration Solution: Designed to fit seamlessly into your hydration pack, each Trailflow water bladder serves as an essential hydration accessory, ensuring you stay hydrated during any adventure, from hiking to hunting.
Premium Water Reservoir Technology: The Trailflow-88TZ redefines the concept of a backpack water bladder with its new “pivoting” fill port design. This allows the fill port to pivot up to a horizontal position for easier filling, making it a cornerstone of Mazama’s line of hydration reservoirs.
Durable and Leak-Proof: Whether you’re navigating rugged trails or facing the challenges of winter conditions, these hydration reservoirs for hiking backpacks are crafted from food-grade, USA-made film to offer reliability and a taste-free experience. The Trailflow-88TZ is built to withstand the most rigorous adventures with its 33% thicker film.
Easy Refill and Maintenance: Emphasizing convenience, the mid-line quick connect allows easy removal of the reservoir from your pack without unthreading your drink tube from straps.
