  • Features

    • Superlight, robust main compartment is made with 100% waterproof Dyneema® composite fabric; white colorway is made with 50-denier Dyneema for a slightly lower pack weight
    • Black colorway is constructed with 150-denier Dyneema, which is more tightly woven for increased durability with a marginal increase in pack weight
    • 3,400 cu. in. (55L) volume is ideal for weekend, section or thru-hikes where resupply points are less frequent, or for trips requiring flexibility
    • The top can roll down to make the overall size of the pack similar to the 2400, but that additional pack space can come in handy when you need it
    • 3 external, solid Hardline with Dyneema pockets add an extra line of defense around the gear you'll want to quickly reach at any time without having to open your whole pack
    • Removable, contoured aluminum stays
    • Hardline with Dyneema shoulder straps with 3/8 in. closed cell foam and spacer mesh; 1/4 in. foam back panel pad
    • Roll-top closure system with side straps for vertical compression; side compression straps for horizontal compression
    • Top Y-strap compression is designed to secure gear
    • Hardline with Dyneema hipbelt with 1/8 in. closed-cell rigid foam; zippered pockets on hipbelt with #5 YKK zipper
