A big backpack is a big investment that you live with for a long time. The Osprey Argon 110 (113 liters, 6900 cu. in.) is huge, extremely well made, and expensive.

Even unloaded, this Osprey pack is impressive. The suspension system and bag are both thoughtfully designed with lots of attention paid to details and quality construction. And it’s lighter than some other packs this size

Being the gearheads we are, The EasternSlopes.com team recently decided to see how much weight we could carry in the Argon 110 before it got seriously uncomfortable.

We still don’t have an answer. We’ve overloaded it with ridiculous weights: 80-plus pounds for a smaller tester, 90-plus pounds for or strongest, and we both had exactly the same reaction: No matter how heavy we load it, the pack itself never gets uncomfortable—it just gets too heavy to carry.

We can easily see using the Argon 110 to do a week-long winter trip (or a two-week summer trip) without re-supply. And if it will carry 80 pounds comfortably, imagine how comfortable it would be with a more-normal load? Great piece of equipment!

Update: Since we wrote this original review, We’ve used the Argon 110 in both winter and summer on more dozens of backpacking trips. We get  more impressed with it every time we use it. It’s one of our go-to packs whenever there’s a bulky, heavy load to be carried.
