Stratos 34L Backpack

With the Osprey Stratos 34 Backpack, you're ready for any mountainous adventure whether it's hiking, climbing, or backpacking for a night. This pack fits all the gear you need for a day at crag, food and snacks for a full day hike, or even the necessary equipment to spend a night out in the woods.

The designers at Osprey shaped this pack's LightWire alloy frame in such a unique way that it optimizes your load's balance as well as enhances the ventilation system with the help of the AirSpeed back panel. Add that to the sewn-in spacer mesh at both the waist-belt and the shoulder straps, and you're ready to tackle anything in the mountains without a sweat. The waist-belt utilizes ErgoPull straps for an ideal fit, and the panel access allows you to get anything out of your pack with ease regardless of where it is.

The blend of high-tenacity nylon and 420HD nylon overlays will handle rocky scrapes and dirt dragging for years, and Osprey even integrated a rain cover so you can continue your mountainous adventures in poor conditions. The Stratos 34 also features a bottom zippered compartment for your sleeping bag, straps for your sleeping pad that you can remove when it's not an overnight adventure.

  • Burly, breathable pack for long day trips or overnighters
  • Tough nylon construction withstands abuse in the woods and mountains
  • Alloy frame stabilizes and balances out your load
  • Ventilated backpanel prevents your back from getting sweaty
  • Integrated rain cover helps keep your gear dry

I've put it through the wringer

I use this for every outdoor outing. from canyoneering to even the littlest hikes. its got just the right amount of room for my camera, tripod, extra jacket/layers, and my lunch. This isnt the lightest pack, but i love it durable build, comfortable fit, and being able to carry everything i need. i highly recommend this pack.

Light, versatile, and plenty of room

I've used it several times

I actually bought this bag for longer, multi day mountain bike adventures and was not sure how it would work out since it's designed for hiking, but it's now a great bag for all sorts of adventures. Since it doesn't have the brain lid of the 36, it works really well for biking because it leaves more room for your head to move around and doesn't get in the way on the downhills. The ventilation is awesome for hot days. I've found there are plenty of pockets and storage room for all my things. I'd use this for a day or weekender bag.

sleek, comfy, poor pockets, tricky fit

The Stratos 34 is a Stratos 36 without the brain lid, and loses a tremendous amount of versatility in so doing. All panel loaders sacrifice loading versatility and efficiency for sleekness, but this pack I think sacrifices too much. The Stratos 24, 34, and 36 sport a vertical front panel pouch this year; it should have been a shove-it pouch like the 50 - preferably one with a map pocket. The current pouch design is rather small and difficult to load effectively. This trait carries over into the organizer pockets. While the slash pocket on the top of the front panel is OK, the main organizer pocket on the top of the bag is simply is a small pouch that drops into the main volume of the bag. As you fill the main bag up, it crowds out the organizer pouch. A better design would have the main organizer pocket immediately behind the slash pocket and tacked to the front panel, so that its contents would remain accessible as the main volume filled. With the present design you must choose between filling the organizer pockets or filling the main volume, and thus the full 34L capacity and organizational features of the bag are often not realized. The load lifter function and adjustability of the Stratos is great, but it's difficult to get a good fit in the bag if you're just under the torso height breakpoint like I am. The M/L is the better choice; maxing out the S/M adjustment causes the bag to flop backwards and one must rely on the load lifters for basic fit. Bottom line - this feels more like luggage than a backpack.

Perfect Day Pack

I bought the pack mostly because I get hot easily and the cooling and ventilation features really caught my eye. I’ve taken it on day hikes and it’s lived up to the claims. It’s so comfy and all the pockets allow me to take everything I need.

Great Daypack

I've put it through the wringer

Fairly light weight. Streamline enough not to snag or to become unbalanced. The velcro adjustment is convenient to swap out with teammates or family members on the fly. This is a great day pack for hot/arid climates and able to withstand a respectable amount of weight if space isn't an issue. 34L is 34L and it trades off a lightweight streamline feel vs. adaptability and extra storage. Which is absolutely perfect for blending in and not looking too "tactical". The rain cover included is a bright color with reflective logos (+1). The frame system could have a higher threshold for abuse and the bottom part of the pack could use some material reinforcement for those rock scrambles. The "Airspeed" back is prone to getting muddy/dirty with thorns ect... However, It's white and highly breathable (+1). Hundreds of miles have proven that it is decently durable and slightly abrasive. I actually wanted to give it 5 stars but wanted Osprey to really have to work for it! I bet they understand ;) - Osprey pretty much nailed this pack. You will not have regrets.

Love your reasoning for 4 stars! Thanks for the great review! Leta Osprey Rep

Perfect size,

I've used it several times

I thought up-sizing to 34L bag would be too big for my needs of daily grab n go to a day hike/overnight bag. . Nope. This pack is awesome. The split main compartment is great to store a packable raincoat in the bottom, plus plenty of room for layers and a camera case, snacks etc. this section can be unhooked to extend the main top load pocket. The hip pockets are big, mesh stash pocket at the top is bigger than I expected. with this pack my back never sweats and it always feels snug. it's stowable rain cover was a pleasant surprise, you won't get caught off guard with this pack. However, the natural curve of the pack is not perfect for a laptop if you want to use it like that. my solution is to just pack a sweatshirt or shorts to fill the void. it works like a charm.

Thanks for the review, Aaron! Leta Osprey Rep

Comfortable, great size

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

Very comfortable pack. I bought the Stratos 32 (S/M) for a week-long trek on Scotland's West Highland Way, where I won't need to carry sleeping or cooking gear, or much food beyond snacks. That trip is yet to come, but I did test it out in the Colorado Rockies this summer on a few day hikes, where I carried a full hydration bladder in addition to camera, extra layers, and rain gear. I loved the fit, and it has plenty of pockets for easy access. I did notice that with a full water bladder there wasn't nearly so much room for all the things I'll need for the multi-day Highlands trek, but then I won't need to carry so much water in the UK, either. All in all, even though I haven't yet used it for the primary purpose, I'm very pleased. Also, it's a perfect carry-on size for airline luggage. Looking forward to keeping it all with me on a trans-Atlantic flight.

Jim, Thank you for the great review! Enjoy your Stratos! Leta Osprey Rep

I'm an Osprey guy

I've used it several times

I have the 60L i got last year and loved that one, so when I was looking for a "day pack" naturally i stuck with the same brand. This has a big main pocket and just enough extraneous pockets to separate the mess you accumulate on a long day hike. The 30L i think is the perfact size and the waist is made like a multiday pack for a lot of comfort. Plus it includes the rain fly which saves you an additional $20. Solid buy.

UpdateGreat as large daypack with camera

I've put it through the wringer
True to size
Size Bought
6` 0"
150 lbs

(Update 2020) Finally used this pack as an overnight backwoods pack. It was an adequate size for one night. I went with my daughter with a child's Osprey pack. I carried the 2-person tent, clothing and her sleeping pad inside, and attached my bag and sleeping pad outside, along with a shovel, raincoat. The bottom pocket held most cooking gear. I agree with Shaun S. that "you must choose between filling the organizer pockets or filling the main volume". I was only able to put small flat items in any of the pockets with the bag stuffed.------------------------------------------------------------------------------------------------- With this bag stuffed and loaded at 30.5lbs total, it remained very comfortable for me. I noticed the weight on the hike, but not discomfort in any one spot. The hip belt did its job and I didn't need to keep adjusting shoulder straps for comfort. The weight was not dispersed too far high and back like other packs I've owned. My back didn't sweat because the ventilated back panel did its job.------------------------------------------------------------------------------------------------------------------------------------------------Final opinion, I'm keeping the 5-stars with understanding that this is best suited as a day-pack and not stuffed to capacity. The Stratos 34 can be used for overnights, but if you're looking for that primarily, I'd look at a different design that gives slightly more volume with pockets more suited for that purpose. ################################################ Initial review (2017) ################ I purchased this bag for the purpose of a large daypack. It could be used as a minimalist overnight pack, and I plan on trying it at least once. My main goal was for holding a DSLR camera and large lens in the main compartment, tripod on the outside, rain gear in the bottom compartment, cell phone and small gear in the belt pockets, plenty of water, snacks, first aid kit, etc in other compartments. It does all this very well with room to spare. ----------------------------------------------------------------------------------------Though not specifically designed as a camera backpack, this pack gives quick access to the main compartment, especially compared to similar sized packs with the popular top compartment above a drawstring. Unlike camera backpacks, it has room for all the other day-packing stuff you may need. The torso height on the Medium/Large Stratos 34 can be adjusted to accommodate my height (72"), torso height (20"). Torso adjustment is maxed out, so the 21" max toro height might depend on a person's build. -------------------------------------------------------------------------------------------------------------------------I've used it a few times and here are my observations: The construction seems solid; my back didn't get sweaty; the weight distribution felt great, with the majority on my hips; the hip pockets worked fine for a medium cell phone; there were no squeaks from materials rubbing inside the pack (silence is key when out in nature); the water bottles were accessible without taking the pack off--for me anyway. I don't plan on using a hydration system, so no comment there. The main compartment zipper works mostly well except around the top corners. It doesn't snag in the surrounding material, but the zipper cover slows it down a bit. I sometimes flip it back when using. The lower pocket is perfect for rain gear or layers, but is designed for a sleeping bag. Only a higher temp, very compressible down bag might fit, as the compartment is pretty small. ---------------------------------------------------------------------------------------Overall I love this bag for my purposes and plan on really putting it to the test. If you're looking for a minimalist overnight backpacking pack, then know your gear and what 34 liters is, and if unsure, chat with customer service for details before buying.
