The Salomon Out Day 20L+4L Backpack is a comfortable, low-bulk, and low-hassle option for all of your day-long adventures. With padded and ventilated straps and a MotionFit suspension system that moves with you as you walk, hike, or run, it's the kind of pack that you'll forget you're wearing until you need it, and then you'll find nothing but pleasant surprises. Hydration compatibility keeps water within easy reach at all times, and offers two different options for water storage--a standard reservoir sleeve, and a stretch pocket on the shoulder straps that fits a 500ml soft flask. The main compartment is expandable by 4L, letting you stash even more layers and gear for varying activity and conditions, while side-access zippers let you quickly access your important items without having to root around from the top of the pack. Plus, in addition to standard gear loops, there's attachment points for trekking poles and ice axes, giving you true multi-sport and multi-season versatility for any dawn-to-dusk pursuit.
