When I got to the end of the trail I met a couple of hikers that worked for an agriculture dept in Tillamook and we talked about packs for a bit. I was humping my Osprey Atmos 65, loaded with about 25 pounds of gear. The guys oohed and ahhed about my pack, too polite to make any criticisms, but I’ll lay out a couple here.
First, I don’t like the bottom chamber. I bought it in a bit of a rush (on a lunch break) and hadn’t noticed that the bag wasn’t a single stuff pack. It has a bottom compartment that zips open for you to put your sleeping bag in. I’ve got an old sleeping back and it doesn’t fit. It probably means I need a new sleeping bag, but I still didn’t like it. The bag makes you pack the way it wants you to, and zippers leak.
Second, it rode a little high on my hips, seeming to move up as I walked. I did some adjusting to make it fit better, loosening the shoulder straps, tightening the sternum. There are probably some things I could do with the internal frame. I’ll have to check that out.
The mesh back panel design was meant to keep the pack off of my back, giving my skin some room to breathe, but I was still sweating even stripped down to my base layer. Still, I think it’s a cool idea and it’s really comfortable.
All in all I think it’s a good pack. But maybe that’s because I spent the cash already. Regardless, I did 5 miles with 25 pounds and had zero strain or pain. I need to spend more time learning how to pack it better.
