The Duthie A. M. 15. 0 is the largest back in the Platypus collection, and it's equipped to handle full days on the mountain so you never have to worry about leaving any gear behind. A roomy main compartment pocket easily stores your rain jacket, snacks, spare parts, and sunscreen, and the three liter reservoir in the hydration sleeve makes sure you never get dehydrated on the trail. Even if the sun beats down on you, the ventilated FloatAir suspension helps provide airflow to your back while the fleece lined eyewear pocket safely holds your sunglasses or goggles when you need some extra protection from the rays. The Duthie also features a carrying system for a full face helmet and pads, pump sleeves, magnetic hose retention, rain cover, and several pockets to keep you organized and prepared for any flat tires or photo worthy spots.
