I purchased the 15-inch ECO model with the upgraded (padded buckskin) shoulder straps from Frost River's distributor in Perth, Australia. I used it for about two years before making a birthday gift of it, and subsequently replacing it with the Sojourn pack with padded sleeve. The Sojourn pack's cotton webbing shoulder straps answered a long-standing question for me with regard to their comfortableness. Fortunately, I find them plenty comfortable! That said, given the option, the more cushy buckskin shoulder straps offered on the Arrowhead roll-top win out, and I wish Frost River would offer such an upgrade on more pack designs. In hindsight, I cherished the Arrowhead pack for several other reasons as well. First of all, although a wide model, it never felt too bulky or cumbersome to carry as a day pack. The ability to adjust the roll (and size) of the pack made carrying enough for three-day trips possible too. I appreciated the roll-closure because of how well it kept the rain and elements out of the pack. On balmier days, the long straps that run over the top of the roll secured my jacket or sweater. I miss having that feature too. The double-canvas bottom and the interior padded slip-pocket, similar to the Sojourn pack I carry now, kept devices safe and sound, and added structure to the pack, which helped it to ride comfortably against the back. Lastly, although I appreciated having side-pockets on the ECO model, I didn't find their design all that appealing. Perhaps if the side pockets featured a different closure-design--roll-top closures, lapped/covered zipper-closures, or buckled top-closures (similar to the Summit Expedition model)--I might have appreciated them more. However, all things considered, this pack served me well, and I recommend it to anyone looking for a strong roll-top day pack in premium canvas, leather and brass. From what I hear, it makes a great gift as well.
