For short-hop performance that won’t leave you parched, Simms’ Headwaters™ 1/2 Day Hydration Pack houses everything you need—and nothing you don’t. Ultra-rugged fabric with a water-shedding DWR finish engulfs 915 cubic inches of advanced river-shuffling storage. Keep pliers, nippers, and fishing tools in check via an accessory compartment, while the main zippered pouch has stretch mesh gear dividers for always-awesome organization. Bundle the 1/2 Day Pack with additional Hip and Chest Headwaters™ options thanks to the convenient Catch & Release modular system, featuring rock-solid magnetic attachments.
