Shed some bulk and travel light with the Marmot Kompressor Star 28L Backpack. Its streamlined design forgoes the bells and whistles and focuses on a comfortable and compressible carry. At 28 liters of storage, this pack is perfect for quick moving day-long missions, from early morning trips to the crag to speedy peak-bagging trail ascents. It's got a breathable Airmesh hip belt, back panel, and shoulder strap system to help avoid overheating when you're hiking in hot summer conditions, and offers hydration-reservoir compatibility to keep you hydrated on those same days. In fact, it's got a convenient hanging clip to keep your reservoir in place as you hike and scramble, as well as a set of stretchy external pockets to keep some extra water bottles handy when you need lots of water for the day ahead. And, true to its name, this pack provides plenty of compression, both when you carry it and when you pack it up thanks to its load-compressing side straps and easily packable design.
