## Our verdict

### Reasons to buy

-   Great construction and quality materials are used.
-   Remarkably lightweight but highly reliable.
-   The clamshell opening makes packing and unpacking easy.
-   Highly flexible because of the "Three ways to carry" design (shoulder bag, briefcase, and backpack)
-   Features a lot of organization plus there's an attachment option on the outside of the bag in which you can attach smaller topo bags.

### Things to consider

-   The laptop compartment can be too tight.
-   No pocket for your water bottle.
-   When overpacked, the bag's dimensions don’t align with most airline carry-on size restrictions.

## What reviewers said

-   "It obvious that a lot of time and attention was given to the design and construction of this bag. Perfect for taking on a trip where air travel, public transportation, and walking are required. Easy to carry, plus the interior is broken up into easy to pack sections that keeps gear and clothes organized."
-   "This bag is everything that I expected it to be, and that's a great thing to be able to say. The overall look has visual impact, not only because of the color blocking, but the style just screams adventure."
-   "For me, this one was a perfect size and quality. Very well made. The material feels great, there are plenty of pockets and room for everything I need. I wouldn't change anything with this one."
