Rating: 5 / 5
Fit: This bag has a superb fit that places more pressure on your lower back, which distributes weight to the hips and keeps your upper back cool. I was impressed with how well this pack vented, even when I was climbing hard.
Durability: After an accidental foot placement had me skidding 30-40 feet down coarse rock, I was sure I'd cut a hole in the bottom section, but the tougher material in the base held up without a scratch. I expect the bag to last a long time, and Boreas backs repairs.
Function: The top-loading is something I'm comfortable with. I found the removable frame sheet to be a great feature. The front pocket swallows a lot of miscellaneous items, and the hip-belt pockets open wide to swallow cameras. The bag doesn't strap closed tightly unless it is completely full, but the included raincover should be enough to keep things generally dry. The top compression strap is useless unless you are at near-capacity, but the lower one works great. The stretch pockets all over the bag feel very durable.
Overall: The roll-top closure isn't perfect, but it's hard to find much of a flaw with it beyond the aesthetic. It's certainly a welcome change from heavy zippers and top lids. My number one concern with the pack before ordering was whether 40L would be enough for multi-day hikes, and with the cavernous main section, I'm delighted to say I'd thru-hike confidently with this pack.
I would be heartbroken if a mesh pocket ripped, since the material is so clean and nice-looking.
Would buy again? YES
