The Osprey Rev 18 is a streamlined hydration pack built for endurance trail runs and high-performance day hikes. Both sizes of the Rev 18 come preloaded and trail-ready with Osprey’s 2.5-liter Hydraulics LT Reservoir.
Featuring comfortable, breathable mesh, the Biostretch Body Wrap harness and Biostretch Bodybelt hipbelt in the Rev 18 are designed to move with you, offering a fit that feels more natural than that of many traditional backpacks. The upper chest strap buckle contains a built-in magnet for fast bite valve attachment, and the two adjustable chest straps are completely removable when unneeded. A highly-innovative touch-screen friendly smartphone pocket safely stows electronics while allowing fully-protected usability. The Rev 18’s reverse spacer mesh back panel and stabilization wings in the bodybelt provide great breathability. The bodybelt also features two zippered stretch mesh pockets for convenient storage.
An insulated compartment in the Rev 18 houses a 2.5 liter (84.5 oz) Hydraulics LT Reservoir and ensures that its contents remain cool. A zippered external entry grants direct access to the reservoir. With the QuickConnect detachable drinking tube that allows for faster refills and Osprey’s Magnetic Bite Valve, the reservoir is innovative and simple to use. The reservoir’s wide mouth is easily accessed by a large, quick-seal cap that further adds speed and efficiency to refills. An anti-microbial treatment fights bacteria build-up inside the BPA and PVC-free reservoir and keeps water tasting fresh and clean.
Also featuring dual stretch mesh harness and side pockets, the Osprey Rev 18 hydration pack is available in your choice of colors and Small/Medium (976 cubic inch capacity) and Medium/Large (1098 cu in) size options. NOTE: Osprey’s recommendation is to match the pack to your standard apparel size.
