Why We Like The Exos 48L Backpack

Whether we're hitting the trail for an overnighter or attempting to set a new speed record on the Pacific Crest Trail, the Osprey Exos 48 Backpack is always with us every step of the way. With a balanced volume, it keeps our packing habits under control, and it doesn't laugh at the strange things we say to yourself as you hike.

The AirSpeed back panel and light-yet-durable alloy frame bestows you with breathability by dumping excess heat out of the sides, and cushioned, ventilated ExoForm covers the shoulder pads and waist-belt for extended comfort mile after fast-paced mile. Even with minimalist hiking habits in mind, the Exos offers plenty of nooks and crannies for snacks, maps, and trekking poles, as well as some quality features. A hydration sleeve offers a place to stash your three-liter bladder, so you don't waste precious seconds stopping to pull out a water bottle, and the raincover keeps your gear dry when the weather turns sour.


  • Lightweight pack for minimalist backpacking or weekend trips
  • 48-liter capacity balances storage space with speed
  • High-tenacity nylon endures miles of use and abuse
