Designed for alpine athletes who log miles at a fast clip, our 25L mountain pack is streamlined for uphill grinds, ridgeline scrambles or epic car-to-car rides. Drop-in bottle pockets allow for quick stash hydration while vertical loops provide a dedicated space to secure trekking poles. Shoulder strap daisy chain attachments organize external gear while also enabling proper sternum strap and buckle placement. Recycled, water-repellent 100-denier Robic® triple ripstop fabric features an Ultra Tear Strength coating for increased material strength. An anatomical honeycomb mesh back panel enhances breathability on hot stretches of trail. Packs into its own internal stuff pocket for storage or travel.
