Designed for on-trail backpacking prioritizing mobile storage and accessibility. This 40L pack is great for the on-trail backpacker or all-day thru hiker devouring miles. Incorporating the latest on-trail features for the on-trail backpacker or sunup to sundown thru hiker, this pack prioritizes mobile storage and easy accessibility for the hiker devouring miles.
Large dual-entry front external pocket for quick grabs without needing to dig through everything inside. Generously sized side pockets and a stretch bottom pocket add even more storage options
Low-profile daisy chains allow countless ways to carry external items for different kinds of trips. Remove or add top-side compression straps depending on needs, or shock cord for oddly shaped gear
With the exterior binding, seam bulking is eliminated within the pack, allowing for more efficient taping and improved water resistance
