Rated 4 out of 5 by from Solid Pack For Long Trips I used this pack on a 5 day adventure on the High Sierra Trail in Sequoia National park after recently purchasing it. Simply put, the backpack was awesome. It did a great job of distributing the weight to my hips and conformed to my body nicely. I had no complaints at all until we went on a 22 mile bruiser on the last day. Once tired the pack felt like it swayed with my body a little more than I would prefer. After repacking my gear to better position some heavier items closer to the bottom and my back this issue went away. I loved the easily accessible pockets and water bladder. I would recommend this pack to anyone planning an extended stay in the wilderness.

Rated 5 out of 5 by from Great Pack This is a very comfortable pack. I took it on a 9 day adventure through the Sierra's from Cottonwood Lakes to Whitney Portal. It is the best pack I've ever used. It held all my gear and could have held more had I needed it to. In the past the packs I've used were a battle constantly adjusting to get comfortable one place or another, with this pack I didn't need to do that at all and I haven't even had the custom molded hip belt yet. I love this pack. I can stop looking for a comfortable pack now, I found it! The only issue I had is the zipper on the sleeping bag compartment snags when I open it, fine when closing.

Rated 3 out of 5 by from Slightly bummed! My last Osprey pack, I bought in 1997 and it is still going strong. When the Xenith arrived I was immediately drawn to the rather cheap looking construction. My first reaction was right. After my first outing (5 days in the wilderness area of Joshua Tree), it looks like I have had it for 20 years. Every single mesh pocket is ripped, and on the first day one of the clips broke on my lid strap. Talk about bummed! Other than the construction and durability, everything else was great. I will say that a full 3 liter water bladder, will bulge out the back pad. All in all, I wish I had gone with a simpler pack. Maybe this was just too Guchi to be true.

Rated 5 out of 5 by from The pack that does it all Great pack! I had the Gregory Baltoro 75 before this and this pack is far more advanced with regards to pockets and suspension. I also owned the Osprey Atmos 65 which ended up giving back because the wire frame was digging into my hips. The weight on this bag is spot on for this size but very well put together. The external pockets don't waste space on the inside of the pack and the padding is amazing. Only complaint which is minor, would be the hip belt needed at three adjustments during a 1.5 K hike. It's minor because we were going up hill and down which could be the reason. It didn't give out which is why I say it's minor. I think the pack performed quite well and will be my primary for a long time. Coming from the Army, I'll tell you this will be your ideal pack for the gear guy.

Rated 5 out of 5 by from Very well though out pack!! This is a VERY well thought out pack!! I have yet to take it out but I have loaded it up with ALL of my gear plus my backcountry photography setup which includes a pro DSLR, 3 lenses, and a tripod. All in all I have about 65 lbs of gear if I were to take all the comforts of home (this includes a -40 deg USGI modular sleep system that I would only use in the winter that weighs 10 lbs) I am totally in love with this pack. The ice axe loops are awesome, the top lid/lumbar pack is very spacious... The elastic mesh on the sides hold my Nalgene bottles very nicely (I don't have any fears that it will pop out like they do on some packs). I could go on and on about this back! Bravo Osprey!

Rated 4 out of 5 by from Nice pack This pack is a bit heavy, but that goes along with it's size and quality materials. The suspension displaces the weight well so that it is not really noticed. I got a larger pack becuase I usually have to carry the overflow for my kids, but it will cinch down well for smaller loads. I used the pack this past weekend on a "Dads/Kids Backpack Trip" so I carried alot of extra items and the pack felt great, I was afraid to weigh it, but I guessing is was close to 45lbs. Overall this is a great pack and I have no complaints. I gave it four stars, because I think anything can improve a little.

Rated 5 out of 5 by from Very versitile pack I purchased this pack for an 11 day backpacking trek at Philmont Scout Ranch. It performed extremely well by distributing the weight well and was very comfortable in many different environments. The multiple compartments are a plus and envied by my fellow backpackers. The external access to the water bladder is a plus as well. You can tell generations of thought went into this pack. Although I purchased this through REI, I did get the waist belt custom molded at my local Osprey dealer and I think it made a difference.

Rated 5 out of 5 by from Wonderful! I've been backpacking for 20 years now and this is the best backpack I've owned to date. I've evolved from ultralight backpacks - the supreme comfort of this pack makes up for the extra pound or two. The bag's many pockets give it the organizational ability of my old external frame packs. The two side zippers make access to all contents incredibly easy. While packing you can choose optimum placement of items instead of worrying about ease of access. The excellent foam pads, ventilated back, perimeter frame, and rigid frame sheet all contribute to a great carry of big loads. The 6 compression staps allow you to scrunch it down when you have light loads. I had my first use of this pack 2 weeks ago. I haven't worked off my Winter weight yet, but made a hike in record time. I believe the comfort of this pack made that possible.

How does one go about getting the hipbelt , etc custom molded?

Asked by: Aliikai Sailor
Select REI stores and other Osprey dealers will have ovens that will be able to mold your hipbelt. We recommend contacting your local REI store to see if they have the capability to mold your hipbelt.

What size water bladder fits this pack?

Asked by: babygirldee
Any size hydration reservoir will fit inside of the Xenith 88 Pack. The 3 liter Osprey Hydraulics Reservoir would be a fine choice.

How much is the rain cover cost for the backpack and why is in not included in the price?

Asked by: Fordiesel250
Osprey did not design a rain cover to be included with the Xenith 88. The REI Duck's Back Rain Cover would be a good choice.

If my height is 190 cm / 6'2 what size is best to take - L or XL?

Asked by: Alexey83
The best way to size a backpack is with a torso measurement. If your torso is between 20 - 22.5 inches, then a Large would work well. If your torso is more than 22 inches, then you'd be better off choosing the XL size. Here is a link to our Expert Advice article on for measuring torso lengths:
