I've been using this backpack for a few days now and so far I don't have any major complaints. TIme will obviously tell. I've been using shoulder bags for most of my adult life and while I do like them for meeting clients and/or an office setting, they're just not practical for travel and being out working on projects in the field. I started researching backpack, specifically roll top because I like the look and I like that they’re expandable to accommodate more gear.What I like about this backpack:1. Modern, sleek, sustainable, and durable design.2. Ample room for gear, clothes, and other necessities. Especially when rolled all the way up. Nice padded protective pockets for both a laptop and tablet, and slots for additional gear/tech.3. Water resistant materials and waterproofed front pocket and back access zippers.Expandable side pockets that can easily accommodate larger water bottles.4. Quick access back zipper for laptop/tablet pockets, luggage strap on back, and a nice key hook/strap inside front side pocket.5. Comfortable back padding and padded shoulder straps (no sternum strap, which I don’t mind) with three carabiner loops on each side.6. Price points that are much less than what companies like Timbuk2, Stubble&Co, and Wandrd are charging.My wishlist for Tomtoc:1. Side mount/compression straps to secure a longer umbrella, taller water bottle/thermos, and/or tripod would be nice. The backpack does have two top loops on both sides of bag that a carabiner paracord (which I was able to do, see above photo) or something like a Think Tank Photo Disguise Strap could be attached to.2. I would have liked the inner lining to be orange, bright yellow, or lime green for visibility when searching for things inside.3. I would have liked the bag to be a little larger at least aesthetically. I’m taller/larger (6’ 1” over 200lbs) so when not fully rolled up it looks a little small on me. Not an issue when the backpacks fully packed and rolled up (expands from 17 to 20L) though. However, I can see the size being a benefit when traveling by plane or when getting around in a city environment.4. Though not that big of a deal, waterproofing the top and front side zippers like the front pocket and back access ones would be a smart move going forward.5. Along with the carabiner loops, I wouldn’t mind seeing a D ring on one of the shoulder straps in the future. But, nothing that a carabiner paracord (see above photo) wouldn’t solve.I still rate this packback high despite it lacking a few things I would have liked it to have. These things weren’t deal breakers for me as most (listed above) have work arounds. However, from what I’ve seen it actually offers a few features the more expensive Timbuk2 roll top doesn’t.
