    Great Pack for Bulky Outings

    • Familiarity: I've put it through the wringer

    Large capacity
    Easy to compress
    Comfortable foam padding
    External Hydration Pouch
    Large, removable lid
    Adjustable fit
    Huge zippered hip belt pockets

    No small size option
    Poorly designed water bottle pouches
    Lid doesn't work well as a hip pack

    I'm a huge fan of this pack for winter excursions. I use this pack primarily for multi-day trips in the winter and extended backcountry trips. I've found that this pack is the most comfortable that I've used for heavy loads. Compared to the Osprey Aether 85, Gregory Denali 100, and MH BMG 105, I found it much more comfortable. I think Osprey did a great job with the hip belts and shoulder straps. They have a comfortable, form-fitting foam and are wide enough to prevent pressure points on the shoulders and hips (something I had issues with on the Denali 100). I've read some complaints about this pack being uncomfortable with heavy loads, but I generally use this pack with around 50-60 pounds and haven't had issues. I've found that as long as I take the time to really dial in the straps for a snug fit, I don't have any issues. Osprey packs do seem to fit me better than most brands though, so it might be a body shape issue for some. I've found this pack to be durable. I've even used it as a practice "victim" for crevasse rescue, and it has held up very well to being dragged against rock and ice when attached to a rope. I've only experienced some minor scratch marks on the lid of the pack. I find the outside hydration sleeve pouch a huge help in the summer for easy access and quick refilling. That being said, the water bottle sleeves on the side can be annoying to get at with the pack on (even trying to use the side hole), so I've resorted to hanging the water bottles from my hip belt inside of an insulating sleeve. That seems to work pretty well in the winter when a hydration sleeve wouldn't be feasible. All in all, I think this is a great expedition size pack with only a few minor flaws. Osprey did a great job with this one.

    Uncomfortable with 55lb load

    • Familiarity: I've used it several times

    I've had a 65L Osprey Atmos for 5yr that I absolutely love. It's taken me on 8day Summer trips across the Sierra and on 2-3day winter mountaineering trips, and it's performed awesomely. But as I progress to longer, higher-altitude winter mountaineering expeditions, a 65L pack just doesn't cut it anymore.

    Enter the Osprey Xenith 105. It has an excellent function:weight ratio. Buckles felt cheap, but I was willing to give it a chance... until I loaded it with 55lb and did a test haul up a local peak. The bag felt incredibly uncomfortable on the lower back.

    I've heard complaints from other climbers/hikers about the metal bar that runs horizontally along the bottom of Osprey packs. When loaded, the suspension of the pack causes the metal bar to get pushed into the person's lower back/tailbone and even causes bruising in a few hours time. At first I thought those people just had weird backbones, but I tried it on my Atmos, and I found I can easily replicate this phenomenon in my 65L Osprey pack--if I exceed its maximum 45lb load range. In my mind, though, it makes sense that a 65L pack becomes uncomfortable with a 55lb load because the load is technically outside what the pack is designed to carry. I was okay with that.

    On the other hand, the maximum load on this Xenith 105 is 70lb. A 55lb load is 20% under the maximum rating, so I would expect it to carry 55lb comfortably. Unfortunately, no amount of adjusting or packing configuration could make it comfortable for me. I'm not okay with that. A 105L pack shouldn't feel uncomfortable with 55lb. Very disappointed with this pack--I promptly returned it.

    Hey there pberg, First let me apologize for so much time passing to respond. I have just now gotten back to where I can see reviews come in and I always like to address them.

    I am sorry your experience with the Xenith 105 was not a positive one. My first comment here was that there is no metal bar at the bottom of this pack. It doesnt have that kind of frame. You may have felt the bottom of the frame sheet, but there is no metal bar at the bottom.

    The materials used (buckles, fabrics, zippers) are all completely dialed and tested, which is why Osprey is the only pack brand that offers a 100% All Mighty Guaranty on everything for as long as you use it. What you may have thought felt "cheap" was actually technology at it's finest: durability with the lightest weight materials.

    Finally, my only guess, based on how you described where you felt pressure, is that the pack was riding too low on your body. The bottom of the pack should be above your tail bone, not on it. I really wish you and I could have connected via skype or something so that I could help make sure that pack with your load was in the right place. By your description, it wasn't, hence your discomfort.

    Now I know that not every pack fits every body, however, I do think I could have gotten the pack to fit you well... I've been doing this for 23 years! Again, I am so sorry that you had a bad experience with this one. So glad you like your Atmos, though!

    Enjoy the Fall,

    Osprey Rep

    "Best gift ever." -Giftee

    • Familiarity: I gave it as a gift but have feedback to share

    "I love the way this pack forms so well to your back. There is a TON of space in this initial trip, I was carrying about 68 pounds and remained comfortable the entire trip. I had read reviews about the buckles on this pack being very far so good, I've done three trips with this pack so far, and the buckles seem to be just fine! If you are an organized person like I am, this is the pack for you; there are a LOT of pockets. My favorite expedition pack so far."

    Brand new at this!

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

    So far, I love it! I keep finding new pockets and am figuring out how to wear it correctly, but my overall first impression is that it is a quality bag that will last me for a while. It will have its first real test in October, I am going on a 4 day trip outside of Moab, I can't wait!

    Large and incharge

    • Familiarity: I've put it through the wringer

    This pack ins like crazy big. I took in on a mountaineering trip. stuffed to the gills. The total pack weighed about 55 pounds. ounce you got he pack on your back you could feel the weight of the pack in your feet. If you need to pack some bulky items or you just need to be able to take 15 days worth of food wit you this is the pack for you!


    • Familiarity: I've put it through the wringer

    I have had this pack for just over a year and it has done magnificently well. I have done over 200km in the field with this baby lugging from a very comfortable 26kg to a miserable 38kg. Under the 38kg load it performed well through three days of solid rain topped off with two days of snow, nothing on this pack failed to work. The external bladder compartment is worth its weight in gold, when you’re buggered and need to refill your water there is nothing worse than having to dig into a back to remove a bladder.

    This pack is good for two to three night trips also, a bit much for just an overnighter though and totally excels when it comes to the long hauls through varied weather conditions coz you can pack just about everything in your wardrobe and still have room left over.

    Osprey Pack Production

    Take a tour of Osprey's design and product development office in Ho Chi Minh City, Vietnam. Opened in 2004 and now employing nearly 30 people, this office allows us to independently design and develop each of our packs. This video provides a glimpse into product conception, prototyping, testing, production, inspection and shipping.

    Nice pack

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

    A great pack! Plenty of room for my things including my Ham radio gear and dog stuff.Not sure how well the buckles will hold up and would like longer straps for my pads on the bottom.Make sure you spend extra time fitting the pack and you will be pleased with it.

    Initial Impressions

      Great pack for long backpacking journeys, plenty of room to fit my rather bulky sleeping bag, tent, sleeping pad, pillow and other essential items. There is exceptional extra room for food and water after all of the essentials are packed i'm very excited to use this pack. The support it provides to your back is remarkable

      Hi, what is the longest possible object i can fit in this internally? I want to take a camera timelapse slider with me to India.

      Hey Andreja - I would say the max length is about 29-30 inches for a rigid object to fit inside the Xenith. Feel free to contact me directly with any additional questions as you continue to prepare for you trip to India.

      Will this pack work for a tall, thin woman? I can't find a women's specific pack of this size anywhere. If so, what would be the equivalent size to the Osprey Ariel 65 size Small?

      Hey Regan, There is a women's version of this pack but its max is 85L

      The Xena

      Anyway, I've found with osprey packs that the hipbelt and shoulder straps are removable that you can make them fit better. I'm tall and skinny and what I've done is got the Large pack and swapped out the hipbelts for the small.

      I do not know if Backcountry can do that. But might be worth your time to write osprey directly about swapping out for smaller womens specific hipbelts.

      Hope that helps

      Hey Alexey,

      Packs are measured by torso length which is from the C7 vertebra (that bump where your shoulders and neck meet) and your hip-shelf (the very top of your hipbone). Torso sizing is as follows: M (18 -21 inches) L (20-23 inches) XL (22-25 inches)
