The women's REI Lookout 40 pack offers a gender-specific fit and comfort for all kinds of outdoor adventures, whether you're enjoying a cool forest hike or a done-in-a-day summit scramble.

  • Features

    • Sculpted shoulder straps, canted hipbelt and short torso length all work together to offer women a comfortable fit
    • Updated shoulder straps and hipbelt provide a soft and ergonomic fit while stiff load-carrying sections preserve comfort under heavy weight
    • FreeFlow back panel features multiple ventilation channels so cool air can flow across your back
    • Spring steel frame transfers weight to the hipbelt and stabilizes the load from unwanted side-to-side movement; perimeter design allows the back panel to conform to your back
    • Panel-loading main compartment makes it easy to organize your gear; bottom zipper adds easy access
    • Hydration pocket can be accessed from the pack's exterior, allowing you quick access to refill your reservoir (sold separately) without digging into your pack
    • Small zippered pocket with soft lining provides an ideal spot for storing delicate items such as sunglasses or electronics
    • Innovative water-bottle pocket design allows a bottle to be stored in an easy-to-reach position, then rotated and locked in place for secure storage
    • Trekking pole attachments feature adjustable lower loops that capture the pole tips, while an elastic quick-clip securely fastens your poles to the pack
    • Simple, pulley-style side compression straps compress more of the bag than traditional single straps and with less extra weight and material than dual straps
    • Quick-release compression straps on the bottom provide an easy attachment point for sit pads or other bulky items
    • Lightweight lash points allow additional gear to be strapped to the front of the pack
    • The REI Lookout 40 pack features a thermoplastic elastomer bottom panel that provides waterproof durability to withstand years of heavy use
