Osprey Packs Atmos 65 Pack - 3800-4200 cu in - 2007 BCS

You either have an osprey body or you don't. I didn't. I like the pack a lot but my body didn't jive. I didn't like how you couldn't get to the waterbottle yourself. I had to ask someone to get it for me everytime I got thirsty. I didn't like the moon shaped compartment but I think the new model is much better. It is worth trying to see if you are one of the Osprey lovers.

A perfect fit! I am 5'11' 185lbs. with a mid size torso. The large Atmos 65 is the most comfortable pack I have put on. I loaded down with 40lbs. or 18 kilos and trekked my way through downtown Manhattan for a good 2 hours. Airspeed system added some much needed relief from sweat and really made the pack feel snug. Never felt off balance or over-burdened. Recommend not packing a bladder in the pack or the airspeed pocket, it will increase sweat. Recommend Rick Steeves’ pack cubes for org. 3 large ones fit perfect in pack.

I've used this pack for a year and a half and it's done everything I've asked of it and more. First off the tech specs are wrong: the pack does have gear loops and ice axe loops, just look at the picture! There is a "shove it" pocket that could hold a shovel. I've overloaded this pack and it always had a little room for more. One liter platy bottles fit just right in the side pockets. I've wrapped a 3/4 ridgerest around a thermarest for winter camping and the back straps were long enough. I use the sleeping bag compartment to hold my two man tent. I shove my sleeping bag deep into the main pack bag. Everything else goes around the hydration sleeve. Rain gear goes outside in the right zipper pocket. Filter and mug in the left one(with room to spare in both). The top lid always has room for that one more thing. Snacks and camera in the belt pockets. I do agree that zipper work is a two handed job. When you get to camp ditch everything and this is the best working hydration pack ever!Remember this is basiclly an ulta lite "frame" pack. If you ditch your bulky, heavy gear and pack right this pack will see you anywhere.

I am 5'10" and 150 lbs and I took this pack on a 4 month trip through Peru and Ecuador and I could not have been happier with its performance. I got the large size frame and it held up against heavy airport abuse as well as harsh 3rd world bus traveling. The frame can dig into your shoulders if the bag is over loaded, but it is perfect for carrying what you need. The multiple access points are great for rummaging and I never had any problems with the zippers or buckles. The pack material stood up great with the exception of some small holes worn through the water bottle holder material after months of Sigg and fuel bottle storage. I have owned Marmot, Mountain Smith, Lowe Alpine, and Kelty packs and none even come close. After using this pack I am now a life long Osprey user.

This pack has two very redeeming features, one serious design flaw and several small pros and cons. The strong points are that it is just over three pounds and very comfortable when fully loaded. Some of this comfort is from the air flow mesh (airspeed) against your back. This air flow area also creates a great place to store a hydration pack or rain gear. Unfortunately, the airspeed frame protrudes into the main compartment and reduces the diameter by half at the middle of the pack (from 14 to 7 inches). You need to be very creative when packing, especially if you need to fit in a bear canister. I would hate to try packing up quick in a storm. Also, if you do manage to fit all your stuff around the airspeed frame it makes the two outside pockets so flat they become unusable. Not to mention trying to get water bottles into the two outside stretch pockets. Pockets on the hip belts are a nice feature but require two hands to operate. Also, the hip belts do not hang open when you pick up the pack so it requires four hands to put the pack on your back. Several small attachment/adjustment features on the pack are clever and useful.

The two things you want most in a pack is lightweight and comfort. The Atmos 65 fills this bill. I think I will keep this pack and use if for long day hikes where packing efficiently is not an issue.

Awesome backpack, it fits just perfect and it is even more awesome when you're doing ultralight backpacking. I'm going to use it for the AT thru-hike.

From my experience, it packs well for up to two weeks (summer) with Bear Cache canister: totaly at around 50 pounds!

The backpack's fullest ability to hold everything is all depending on your packing skill and what you're bringing.

Also, I've used it for 4 day hike during the winter. It works really well and it kept all of my stuffs dry when I had to set up my tent as for emergency shelter and left my backpack outside with the snowstorm covering it up. I'm 5' 9", 165 pounds and I have Medium. It does really depends on your Torso size! It's not that flexible with the size so get the right one!

For context: I am a 5'7" female. Average size.

I got this a couple of years back when it was first introduced. It was my first new pack in years, and I was amazed at the difference between my old pack and this one.

Things I like about this pack: very lightweight. Great distribution of weight - my shoulders were happy for days. The ventilation area doubles as a place to put your water reservoir if you want to make more space inside the pack. The pockets on the hip belt are incredibly handy for small items (tiger balm, lip balm, tissues, whatev). The extra room at the bottom for sleeping bag was very handy. also good for storing tent parts. There are a number of access points to get at your stuff, so as long as you know how you packed your bag you can get to stuff very easily.

We were up in the wilderness areas of the Adirondacks and carried bear proof containers in this bag and still had room for everything else.

Things that need improving: One of the elastic straps on the outside broke my first time out. This made me sad, as it was holding in my trekking poles when I didn't need them. I made it work, but they leaned awkwardly, which made tighter areas (trees and whatnot) a little tougher. This is a minor thing, though, as the part is easily replaceable.

Also, the curved structure of the pack makes for a very comfortable ride, but you have to learn to pack around it. Easy enough.

Overall, I'm not sad I paid full price, and would do it again. I don't expect to need another pack for years to come.

The overall design is great and well thought out. The ventilated harness system worked great on my recent snowshoe trip to help keep my back from sweating. Very light with many versatile design features. The only complaint that I have is the length and location of the straps for your sleeping pad. The two points at which the straps are sewn are so close together, and the straps are just barely long enough, that is difficult to secure a full length ridge rest to the bottom of the pack. Although I suppose I could just buy a longer set of straps. Otherwise I have not yet found any other negatives.

i got this pack as a gift and recently took it on a trip. during the hike i noticed that the titanium frame at the top of the bag was digging into the back of my shoulders. it wasn't extreme pain but a considerable problem. i have heard other complaints about this as well. osprey did good at removing the weight on this bag but all they weight they removed was in the padding...

Picked this pack up last week for a weekend trip. Overall it was a good pack, but not ideal. The frame protrusion into the pack makes for a cool and sweat-free back, but makes it a little more difficult to pack gear. I was carrying around 50 pounds and I think this was just out of the comfort range of this pack, as my shoulders were feeling it by the end of the trip. Once at camp and a few pounds were shed the pack was awesome for day hikes in the area.

This is a great pack! It was very comfortable and the ventilated back panel kept my back breathing well. I had it packed pretty tight but never really noticed the weight while hiking. The front pockets worked great for carrying a personal camp stove and extra lenses for my camera and the sleeping bag compartment was a great fit with the marmot helium eq. I think that the only complaint that I have is that it was a little akward packing the gear around the curved frame but once everything was in it was great.

Great pack with great features! It just didn't fit. Tried large (in store) and then tried medium. Shape and curves of backrest makes it very size specific.

its a great pack after you get you're fit down, but until you get rid of the titanium frame dig can be a bit painfull... no major complaints and it even stands up to aggressive deer!

Run, don't walk, away from this product. This is the most uncomfortable pack I have ever used.

I'm a 5"10" man, 160 lbs, in shape, typical build. I bought a "Large," which still was way too short in the torso. Despite lots of fiddling, the pack still put enormous weight on my shoulders, and crunched me over, bent down like a troll hauling a wooden box of rocks on my back. Even with the waist belt up against my ribcage, the shoulder straps bore down hard on top of my shoulders, and threatened to snap my collarbones. The shoulder straps are not anchored at or above your shoulders (like a real pack), but back down behind your shoulder blades.

Then, to make matters worse, the shoulder straps and waist belt have about as much padding as a small to medium hydration pack. Perfectly adequate if you are carrying 70 oz of water and an iPod and nothing else. But if you're doing overnight backpacking? They'll feel like unpadded 1-inch webbing.

The final, fatal, crippling failure is the waist belt. It is attached to the pack in the back center of the pack, not the sides of the pack. The two waist belt halves are anchored about 4" apart, right behind your lumbar vertebrae. This creates bizarre, torturous pressure points and weight leverage. With me, it resulted in strains all the way down my thighs, hamstrings, calves, Achilles tendons, etc. Then, to top it all off, the frame digs into your hips and shoulders. This pack gave me the most painful 1-night backpack trip of my life. It was my first use of the pack, and will be my last. I would give it away for free, but there's nobody I hate that much.

If you like style over function, consider this pack. It has all kinds of gimmicks, gadgets, whirlygigs, and those weatherproof nylon zippers that last for about 10 "zips." If you want to carry 10 pounds for about 3 miles, this pack might not be too much of a disaster. Otherwise, this pack is a statement on how pack-making has gone off the weird edge, selling consumers gadgetry and design "innovations", instead of functionality. If you built your own pack out of two-by-fours and heavy canvas, it would be more comfortable than this instrument of torture.
