A solid backpack. I needed a new everyday carry backpack. So far these are my impressions after about a month of use and some travel. First, I wish it came with a removable waist strap. When it's heavier or on long days, it would be nice to have one. For this I have it a 4 /5 for comfort. If Tortuga really wants to add extra comfort, I suggest them to add a removable waist strap. Regarding size as long as the bag is not stuffed, it fits inside Frontier airlines personal item size which I thought was awesome. This means it's good for my everyday use and even travel as a personal item. Now a couple design opinions. The zippers on the front face of the bag open upwards relative to the side handle. It's a minor point, but if I lay the bag on the side like a messenger bag, the front zipper needs to be opened upwards. Just seemed counterintuitive. My 15" laptop fits the slot, but when I put the laptop with the laptop cover, it won't fit the laptop slot. Also the tablet slot which is in front of the laptop, I wish it went down further, all the way to the bottom of the laptop slot, because then I could fit my 13 in laptop. All these are minor concerns. I don't really have the budget to compare to other backpacks, but it's nice and an upgrade from my old previous backpack. For now, I plan to use it all the time and keep it a long time.
