The smallest in our lightweight range, the 30L Hesper is a single compartment pack designed for everything from quick day missions to ambitious overnight hikes. It's made from UTS-coated nylon for lightweight reliability, secured by a zip along the top, and stretchy front and side pockets let you keep bottles and snacks outside the pack. It's also hydration bladder compatible, so you can thread the hose through ports on either side of the top of the pack and stay topped up without stopping. Its HeliumAir harness doesn't require an internal frame and it's among our lightest to date. Its construction balances a minimal design with maximum carry capacity, and the 30L version is supported by a fixed foam back panel and fixed hip belt for support across activities. A multi-purpose backpack that's as tough as it is light. Made with UTS-coated nylon and our lightest harness to date.
