It's for backpacking - something a bit more ultralight than I had previously:
I absolutely LOVE it and it's so comfortable, but it was a bit of a hassle to order it from the U.S. I should have had it shipped to Michigan but I was eager to get it!
I did a fair bit of research and this one was the compromise between weight and durability I was looking for. And...do you remember when I met the PCT thru-hikers at WS100 last year? This was the pack they had and I was a bit starstruck by them so I am sure that factored into the decision. :-)
