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
  • Tensioned backpanel keeps weight off your back for extended comfort
  • Highly ventilated for breathability during long days on the trail
  • Gearloops galore offer extra spots for poles, axes, gear, and snacks
  • Sleeping pad and compression straps can be removed to shave ounces
  • Osprey places emphasis on packs with comfortable back panels

Light is Good

I just purchased and used this pack for the SHR, 1st section. I was overly concerned at first having read too many comments here and on other sites about issues that mean nothing to the hiking experience. This pack is advertised as day pack but Through Hikers are enjoying the 2 pound drop over the Atmos and other sturdier packs. Bottom line, light while performing to intended and acceptable standards is better! Period. I appreciated that Osprey reinforced the very accessible water bottle pockets to prevent shoving the bottle through the expandable material with repeated use. This is a 100% real improvement and greatly appreciated given the number of times I extract and return my bottles in a day. Belt pockets? Maybe use once a trip, don't care about belt pockets, rookies. Loops on the bottom? Just allows you to carry too much weight in an unprotected area. (Once cut through 2 protective layers and a tent floor by carrying my tent external and low through the brush.) Bottom line, keep the improvements to high valued components Osprey. The length ran alittle short on me and I converted from a Atmos 5 liter in a medium length. The Atmos has a length adjustment, the Exos does not. All the complaints about loops and pockets, again, who cares when you are looking to drop 2 pounds off base weight. All in all, this is an excellent pack, doesn't look it but it is sturdy. This week long trip had little impact to the pack. My brother took one 700 miles up the PCT and it came back in reasonable shape. Talk to people who finish trips, ask what they used and what they dropped along the way and why. Osprey is high on the list of backpacks that make it to the end. Nothing lasts forever, we'll see how many miles this pack lasts. Shoes barely last 200 miles these days. Basically everything is a consumable and I'll take 700 miles as a good measure of durability these days.

John, what a great review - thank you so much. Great feedback and excellent points! Happy Trails, Leta Osprey Rep

I’m about to pull the trigger on this pack. I’ve been reading reviews for a few months now. I CONNOT believe how many people have given it 3 stars because of damn hip pockets! Rookies! Thanks for the boss review.

Osprey Exos 48 L - Ultralight Weight!

I've used it several times

I was given the Osprey Exos 48L from Backcounty but this review is my personal opinion. I used the Osprey Exos 48 most of this summer on hiking trips throughout the Elk Mountains around Crested Butte and Aspen, Colorado. The Osprey Exos 48 pack hits all the key points of performance: its ultra lightweight, extremely comfortable and has all the essential features needed for extended overnight hikes and campouts. The breathable modules on the shoulder straps allow air to flow through and provide a very "airy" feel to the shoulder straps. The hip belt fits snugly around the waist. The various thin straps that sinch your gear are well positioned and well thought out for all hiking essentials. I love the deep, open-ended pockets on each side that can fit water bottles, which you can remove from either the top or bottom. The Osprey Exos 48 has plenty of room for all your hiking/camping gear. I hiked miles across the Elk Mountains and never felt the need to remove the pack due to being heavy or uncomfortable. I highly recommend the Osprey Exos 48 for the experienced and demanding thru hiker.

Marcus - Thank you so much for a great review! Enjoy! Leta Osprey Rep

Excellent! Leta Osprey Rep


Is there a place on the exos to strap tent, sleeping pad, and sleeping bag? Also, is the term ultralight just used to describe the feeling of the pack, or does it mean that weight and storage is limited?

I saw a youtube video where the guy packed both the poles and tent within the bag.
