An ultra-lightweight option for thru-hikers or fast-and-light backpackers, the award-winning Buttermilks 40 Women’s pack reflects a commitment to simplicity and functionality. The top-loading pack weighs less than 3 pounds and can be reduced to just 1 pound, 15 ounces by removing the framesheet.
A well-cushioned z-foam backpanel and die-cut PE framesheet work in tandem to provide lightweight and ventilated support and stability. When you prefer to travel light, the framesheet can be easily removed with a quick pull on its integrated easy-access handle. Contoured padding in the shoulder straps and hipbelt offers additional comfort and aids in both fit and load control. A sliding sternum strap and load-lifter straps further enable you to fine-tune fit. To ensure that you experience a proper fit, the Buttermilks 40 Women’s pack is available in Medium (fits torso lengths from 16”-18” in length) and Large (18”-20”) torso sizes.
The main, top-loading, 2563 cubic inch-capacity compartment employs a lidless roll-top/cinch-down closure to keep contents secure. A large front stretch-fabric pocket serves as a “stuff it” storage option and keeps extra layers in easy reach. Stretch-fabric side pockets are ideal for water bottles and other gear. Large, zippered hipbelt pockets keep essentials close at hand.
Other features include tuck-away daisy chain attachment points, hidden gear loops on the shoulder straps and an included rain cover. A lined internal sleeve makes the Buttermilks 40 Women’s pack hydration system (sold separately) compatible.
