- Lightweight and Shatter-Resistant Construction: Strategically engineered using high-strength, BPA-free plastic to be 50% lighter than stainless steel Rambler Bottles while remaining virtually indestructible against drops and impacts on the trail. - Yonder® Tether Cap: Features an intuitive two-part system with a controlled spout for easy drinking and an always-attached tether to ensure you never lose your lid while refilling or cleaning in the wild. - 100% Leakproof Performance: The precision-molded threading and gaskets provide a secure, airtight seal that allows you to confidently carry 50 oz of hydration inside a pack or clipped to a harness without risk of soaking your gear. - Clip-On Carry Design: Integrated handle within the cap architecture allows for easy attachment to a carabiner or backpack strap, facilitating hands-free transport for high-volume hydration during long-distance treks. - Maintenance and Longevity: While built for extreme durability, handwashing is recommended to preserve the product's finish, clarity, and structural integrity over years of heavy use.
