The Salomon Trailblazer 30L Hydration Pack is a lightweight, comfortable, and versatile pack that's appropriate for hiking, biking, and everyday wear. We like the padded and vented comfort harness, which feels good for both active and casual wear, and the 30-liter capacity, which works for everyday commutes, all-day hikes, winter hikes, and hut-to-hut adventures. There's also plenty of pockets to stash our snacks, gear, and shed layers, including convenient hip-belt pockets that gives us easy access to small items without taking off our pack
