CamelBak Ambush™ 100oz Mil Spec Crux

The CamelBak Ambush™ 100 oz Mil Spec Crux Hydration Pack is a compact, low-profile tactical hydration pack designed to keep you maneuverable and ready on short missions or active excursions. Built for demanding conditions and inspired by military use, this pack incorporates a 3 L (100 oz) Mil Spec Crux reservoir that delivers 25 % more water per sip for efficient hydration without slowing you down.

Unlike traditional hydration packs, the Ambush allows external fill access so you can rapidly refill the reservoir without removing it or its tube from the pack — a big advantage in the field when time and ease matter most. The durable 500-denier double-rip Cordura® fabric withstands abrasion and rough use, while top and bottom external zip pockets provide storage for daily essentials.

Designed with tactical readiness in mind, the pack features a low-profile Mountain™ MOLLE panel for accessories, side-release shoulder straps for quick removal, D-rings for tube management, and an adjustable sternum strap for a secure, stable fit.
