Buttermilks Lightweight Backcountry Pack (Farallon Black)

45L & 60L Ultralight Multiday Technical Pack

  • Winner of the 2012 Backpacker Editors’ Choice award, the Buttermilks is a sleeker variant of the Lost Coast, made with lighter materials. We also took the top lid off and gave the pack a roll-top drawstring closure. The Buttermilks has the same functional features as the Lost Coast, making it just as versatile and ideal for long or short multiday trips.

    Lightweight and uncomplicated, this pack is designed to carry all your gear and enable fast movement. We use our Z-foam suspension with more weight-conscious materials and construction for this backcountry pack.

    The Buttermilk's namesake is a popular climbing area twenty minutes west of Bishop, CA. Find out more about it here.

  • FABRICS: Most of the body is made out of ultra-lightweight yet strong nylon material (Nylon 140D Ripstop). It has a special silicone/polyurethane coating that makes it highly tear resistant. The bottom material uses a thicker version of the body material (Nylon 420D) for more durability.

    SUSPENSION: Molded, perforated Z-foam back panel and removable aluminum frame and PE sheet suspension. Can maintain pack structure or cut weight for lightweight travel.

    BODY: Key body features include: ribcage construction for strength and weight efficiency, roll-top drawstring closure, dual hidden daisy chain rows and gear loops, hidden daisy chains on padded shoulder straps, easy access single hand use zippered stretch pockets on the padded hip belt, adjustable sternum straps with emergency whistle, full-face front stretch-fabric pocket with welding tape reinforcement, front drainage point at front stretch pocket, two stretch-fabric side pockets can accommodate water bottles and miscellaneous gear, dual hydration ports with hydration sleeve and bladder hanging clip.
