The Crux Quick Link Lumbar Reservoir Kit 50oz (1.5L) features HydroGuard antimicrobial technology to reduce odors, discoloration, and wear inside the reservoir and tubing.

Its low-profile, oversized fill port and Air-Light Tritan cap enable easy filling and cleaning, secured by a Quick-Snap design that locks with a quarter turn to prevent over-tightening. An ergonomic handle simplifies refilling. The 70/100oz reservoirs include an internal baffle system for improved packing size control and stability. Enhanced Crux PureFlow tubing, combined with an updated on/off Quick Link valve and leak-proof BigBite drink valve, delivers 20% more fluid per sip.
