Looks great, feels great
Reviewed by John R. - September 15, 2017

A Snazzy Backpacking Buddy!
Reviewed by Paul V. - April 9, 2017

Likes: An extremely comfortable and durable pack. The ventilation system looks like it should hold up well over time. I can my gear in the pack well, and not all of my equipment would be meet that vague standard of "ultralight." The frame also does a top-notch job of transferring weight to my hips.

Dislikes: Haven't found any so far. If someone can find a way to maintain all the features while making it a little lighter, well, I'd probably buy him or her a beer!
