My first reaction on getting it out of the packaging, was what a lot of straps.
As a minimalist and extreme ultralighter, my initial thought was there will be alot of trimming going on.
This pack is designed to fit x-Large down to x-small torsos. I planned to check that theory out immediately. I'm up at Lake Yellowstone. When the superintendent came for lunch, I brought out the pack, asked him to be my guinea pig. He is 6 foot 3 inches tall, about 240 pounds of muscle. He was wearing a heavy sweatshirt. At first it was a hard fit because I had cinched everything up to fit me, at 5 foot 2 inches tall, 115 pounds. Once adjusted properly, he said it fit fine. It looked like a day pack on him, though. The carry capacity internally of this 3 pound pack is 3,000 cubic inches. It feels amazingly light.
