The latest addition to NEMO's backpack line, Persist is the quiver killer for mountain adventurers everywhere. Armed with our exclusive CERO fabric and CCubed cushioning, this technical pack boasts a clean, rugged exterior and enhanced back panel design for a comfortable carry even when loaded with the burliest mountain toolkit.Designed for multi-day challenges, the 45L capacity features a top-loading main compartment with zippered lid, a side zipper opening to easily access gear, and a robust lashing system for peak modularity and versatility. Equally notable are the pack's easily accessible storage options built into the shoulder straps and waistbelt, including a tuck-away water bottle pocket that always keeps hydration within reach. Part of our fully recyclable Endless Promise collection, Persist features groundbreaking, sustainable materials that surpass traditional options while helping us close the circularity loop. Used in a burly 300D/900D ripstop weave on the pack's exterior, the CERO fabric is solution dyed to reduce waste and is up to 20x more water resistant than the industry standard. CCubed, a recyclable foam alternative, remains the cushioning of choice on NEMO packs and excels in its already impressive wicking abilities thanks to its placement on a new wraparound back panel design engineered to continuously pull sweat away from the body. The pack's shoulder straps and padded waistbelt are also reinforced with CCubed to sit comfortably and evenly distribute weight. Between its thoughtful details and a tough exterior, this pack is ready to take on rock, snow, and ice pursuits with ease — because why choose just one?
