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.



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.
