Moving fast, traveling farther. The Arc'teryx women's Aerios 45 takes you on quick overnights, supported thru-hikes, and light and fast multi-day trips. Its carry is comfortable, and the material is gridded with a liquid crystal polymer ripstop for exceptional strength. The main compartment holds larger gear, while small essentials stash in secure pockets on the hipbelt, harness, and pack sides. A daisy chain and bungee system add storage options and the AeroForm back panel is breathable and comfortable.
