Rated 5 out of 5 by from Amazing pack So far, this pack has been everything I could have hoped for. It is rock solid and carries a load around 40 lbs like a breeze. I'm sure it would be comfortable with a bit more. The back panel isn't quite as well-ventilated as my Atmos 50, but I gladly give up the ventilation for the more solid frame and thicker cushioning. My shoulders and back felt great after miles of hiking with significant elevation change. There are plenty of storage options and various ways to access the main compartment. I highly recommend this pack and feel the extra weight vs similarly sized Osprey Atmos and Aether packs is worth the more sturdy pack, as the more substantial cushioning more than overcomes the extra pound or two in the pack.

Rated 5 out of 5 by from great pack I have been out twice with this pack on multi-day trips on local trails. First time out was with my young daughter and I was packinng a lot of her gear. The pack was around 45lbs total and the terrain was nothing but climbs and descents. This pack carried the load like a champ.my only complaint is that the side mesh pouches are hard for my alligator arms to reach...but no biggie.great pack that is comfortable to wear all day.

Rated 5 out of 5 by from Great Backpack!!! I bought the Osprey Xenith 75 this year and have used it on 3 backpacking trips. What a great pack! The fit is great, carries the load very well (I had approx 50 lbs for each trip), and has plenty of pockets for organization. The external hydration compartment is awesome - no need to mess with the contents inside of the pack when refilling water. This is the most comfortable backpack that I have owned. Highly recommend.

Rated 5 out of 5 by from Great pack for Search and Rescue I use this for SAR and it is AMAZING. There's plenty of room for 48 hours worth of clothes, sleeping bag and your food items. Also has so many pockets for all sorts of gear.

Rated 3 out of 5 by from Great suspension, too finicky My Xenith 75 replaced an old Marmot Glacier pack (the year after Marmot bought Dana Designs) of similar capacity which had served me well for 15(?) years. I'm 6'6", 230-260# depending on how much Ben & Jerry's I've consumed of late, so fitting me is a challenge. This Xenith does so, with fantastic adjustability in the torso and belt. Some competitors advertise ranges in torso which aren't accurate -- the Xenith's is, at least on the high end. It is very comfortable. My old Marmot advertised something like 60+# capacity, but that was stretching it. I'm not happy carrying a load over 40#, but this pack can do it comfortably, while breathing well. The lid explodes easily and is readily adjustable. The cons: (1) Durability -- the side pockets are a stretch material that showed signs of fraying after my first trip. Holes are present after only a few. One of the compression straps is fraying. The straps are narrower and thinner throughout, and the buckles are not bulletproof. I would be concerned taking it mountaineering. The pack material is not built to last. The cynic would call that planned obsolescence. (2) Too busy -- Osprey could shave substantial weight that could be invested back into durability (while saving manufacturing costs). For example, the bottom access zipper, seen on most packs these days just adds weight and expense with very little payoff -- 99% of the time, one takes out one's bag at the end of the day anyway and the access area is difficulty to stuff a larger bag into anyway. Similarly, there are two outside zip pockets that, if you've filled the pack, you can't really use for much anyway. Ditch those and save some weight. I'm not a big fan of the little pockets on the belt (I know many folks are), which are not very durable -- ditch those and save a couple more ounces. I would love to see Osprey simplify this pack and invest the savings back into toughness.

Rated 5 out of 5 by from GERA REVIEW: Xenith 75 from Osprey This was my first experience with Osprey's all-new Xenith line of packs. I tested it over many miles and it has become one of my favorites. Check out my full review in my video.

Rated 3 out of 5 by from Didn't fit me well I really wanted to like this pack. It has all the features I want including multiple pockets, easy access to the inside and good useability. But, I just couldn't get it to fit well. I compared it to the osprey aether and the aether seems to keep the load closer to your back and feels more balanced. The aether does not have as cushy a waist belt, but carries better for me. The aether also has a better ventilated back panel. It would be an great pack for someone it fits.

Rated 1 out of 5 by from wanted to like this pack, but ... GOOD: best hip belt pockets I have seen on any pack. 2 zippered pockets on either side of front work well, even when pack is stuffed full. Seems well-built. Buckles are sturdier and easier to use than those on Gregory packs. POOR: zippers on brain are on the back, just like most other pack brands, so things fall out too easily. these should be either on top or in front, but most pack designers just don't seem to get it. BAD: mesh side pockets have large holes allowing you to stash and access water bottle horizontally, but these holes cannot be sealed limiting the use of these pockets for anything else. And, even when using them as intended for a water bottle, the bottle drops out too easily and cannot be fastened in. TERRIBLE: this pack leaves less room in the back of the head than any other pack I have ever tried. As a result, you cannot bend your head backward to look up. Maybe your head shape is different than mine, but I tried two different sizes and every adjustment I could find and this is a show-stopper for me. Gregory and REI packs I tried do not have this problem. Returning to REI.

Is there enough room in the main compartment for a large bear canister, for examp a Bear Vault BV500 or a Bearikade Expedition? Could the bear canister be carried sideways (that is, with the long axis of the bear canister horizontal rather than vertical)?

Asked by: BSquared04
A bear canister will fit into the Osprey Xenith 75 Pack vertically, but not horizontally.

If I order an Osprey pack from REI.com and have it shipped to my home, can I bring it to a store to have the custom molding done?

Asked by: Texas Ed
Most of our stores have the capability of molding your Osprey hipbelt. We would recommend giving the store a call to make sure that they have the proper oven.

Hi im 13 and I'm looking for a backpack to do a 300 plus mile backpacking trip will this fit a smaller waist?

Asked by: Nathanwin
The medium hipbelt will fit a waist measuring 30 to 34 inches. If your waist is smaller than that, you can order the small Osprey BioForm4 Custom Moldable Hipbelt in addition to the pack. Once you receive both items, you can swap out the hipbelts and return the belt that came with the pack for a full refund. https://www.rei.com/product/846417/osprey-bioform4-custom-moldable-hipbelt-mens

Looking at the Osprey lines they offer two 75 packs the Xenith and the Volt. What makes the Xenith 75 so much more expensive then the Volt and how does that difference make it worth the extra money?

Asked by: LCKerr
The Osprey Xenith is a deluxe pack designed for anyone carrying large loads on extended trips. It offers great features like a suspension system designed for comfort even with heavy loads, and great organization with pockets and multiple zip access points into the main compartment. All the while, Osprey has managed to keep the weight down, compared to other packs in this category. The Volt is meant for the hiker who likes simplicity. This packs offers value-conscious users the chance to buy a quality pack that truly fits and carries well. It has all the essential features, but is light on bells and whistles making this pack lighter weight and great for weekend and multiday trips.
