Why We Like The Exos 58L Backpack

From long weekend getaways to minimalist thru-hikes, the Osprey Exos 58 Backpack has everything we need for lightweight trail comfort, and nothing we don't. A removable daypack lets us take short, exploratory trips from our campsite, and plenty of mesh pockets and gear loops provide the capacity for maps, trekking poles, and snack stashes. Where the Exos truly shines is in the form of the comfort it can provide. The combination of well-ventilated AirSpeed back panel and the light-yet-durable alloy frame brings a lot of breathability by dumping excess heat while you hike, with mesh and energy gel cushioning lead points.


  • Ultralight pack for multi-day trips and thru-hiking
