Exos 58L Backpack

From long weekend getaways to minimalist through hikes on the AT, the Osprey Exos 58 Backpack has everything you need for lightweight trail comfort, and nothing you don't. A removable daypack lets you take short, exploratory trips from your campsite, and plenty of mesh pockets and gear loops provide the capacity for maps, trekking poles, and snack stashes; an integrated rain cover protects your gear on rainy afternoons and compression straps keep everything under wraps. But 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 out the sides while you hike, and ExoForm covers the shoulder pads and waist belt with mesh and energy gel for the ideal cushion needed over weeks or even months on the trail.

  • Ultralight pack for multi-day trips and through hiking
  • 58-liter capacity keeps things minimalist on longer treks
  • High-tenacity nylon endures miles and 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

Great Pack!

I've used it several times

This pack was great for a two night trip. Plenty of room for gear and easily accessible. The removable brain pocket is very nice and allows you to break down to a smaller size. The ventilation system on the back kept me nice and cool, even in the intense alpine sun. Hip pockets would be nice for snack and other things you might want accessible while walking, but all in all, a great pack! Will use again and highly recommend.

Amazing Harness

I gave it as a gift but have feedback to share

My buddy doesn't backpack much, but was really happy with the way this pack disperses weight over your hips and away from your shoulders. It uses Osprey's most advanced, Anti-Gravity harness system.

Comfortable Support

I gave it as a gift but have feedback to share

Feedback from a friend: "The backpack was great. It was comfortable enough to utilize for a multiple day hike. The pack had great support and allowed my back to breath. Numerous pockets will allow you to fit almost all of your camping needs in this bag." I'll add something myself. We in 38 miles in 3 days and my friend had never been backpacking before. The fact that he never complained about shoulder fatigue or any other pack-related discomfort is a testament to Osprey's unparalleled suspension systems. I should also note that while he says it can carry ALMOST all of your camping needs, we spent three days on the trail and had everything we needed, so really it has enough space for ALL your backpacking needs for a 3 day trip. He even carried the tent (I had a tripod instead on a 48L bag.)

no hip belt pockets!

I returned this product before using it

Be forewarned! Osprey changed the design of this backpack. It is still really light weight and well constructed, but they removed the hip belt pockets and the shoulder strap pouches. I was really looking forward to the hip belts pockets as my current backpack lacks those. I was researching buying and adding some sort of pockets but, wait!, I found a new Exos on ebay in same size with pockets! Yeah.

Poor quality

I've used it once or twice and have initial impressions

The bottom of the pack frayed and tore through after one overnight backpacking trip. One of the clips for the brain broke almost immediately after the first use as well. I have owned other Osprey packs and had not experienced such poor quality.


Steve - PLEASE send this back to warranty at Osprey so we can take care of this for you. We do use lighter fabrics on this pack (vs other heavier packs), and I do not know what the circumstance was that created the hole, but a sharp tear can go through anything, no matter how long you have had it. It does not seem to be worm down. And the clip for the lid? Really, not sure what happened, but we will absolutely make it right. This is why we have the All Mighty Guaranty. No matter what, we have your back: our fault, your fault, the bear's fault... no matter. Please start a warrant process at www.osprey.com and they will get you covered! Thank you for writing - Leta Osprey Rep

My hips hurt

I've done two 7 day through hikes with this pack in addition to several weekend trips. It's pretty sturdy and relatively lightweight. I have the 58L which holds plenty of gear for me and my wife. My only issue is that the hip straps are quite uncomfortable. They're VERY small compared to most other packs and the plastic adjusters extend beyond the hip pad which makes them prone to digging into your abdomen/pelvis. OUCH! I got some pretty decent sores on both my hips from a through hike last year. However, I found that if I loosen the hip straps and carry more weight on my shoulders that it made my hips more comfortable. However, my shoulders get a little more sore than they should. From my experience, a good backpack should rest comfortably on your hips with most of the weight distributed there. The shoulder straps are really just to prevent it from falling back. There shouldn't be much weight pulling down on your shoulders... I have to admit I'm a bit disappointed with the product... On the upside I do tend pack pretty light (<25lbs) so it's not that big of a deal if I have to "shoulder some of the burden." :/

I've used it several times

Fantastic pack, unbelievably light. I just got back from a 15 mile trip with it, no issues. I really like the straps and padding, and the ventilated back is so nice. It's very easy to center your load and adjust straps.

I've used it several times

Ouch!! Shoulder straps left welts and scrapes on my collar bone. Hip belt left abrasions both sides of my tailbone. Had 30# in the pack. Maybe a solid day pack, but not good for taking any overnight gear. I want to like it, but it keeps hurting me! The pockets are nice....


Exos Series

Check out this ultralight pack with incredible ventilation

I was recently given an older Exos 58 that has never been used. It's new, spotless, perfect... just older. Is there a way you can determine the year model/age of this pack? Is the color age specific? -L. McDaniel
