The Trailflow Delta is an insulated hydration reservoir built for high-output activities in demanding environments. Constructed from puncture-resistant mPE film with reinforced welded seams, it holds up under rugged field use while remaining BPA-free and taste-free. The VYPR VALVE™ system features a high-flow 3-way bite valve with a Quick Connect Dock mouthpiece, allowing users to swap in filtration systems or alternate attachments on the move. An oversized 88mm threaded fill port makes refilling, ice loading, and cleaning straightforward, even with gloves on.
