This bag has great quality like all other Gregory bags. I use this bag as my main travel bag and it fits great as a carry on. The only down side to this bag is that when loaded heavily it sits kind of funny. Overall a great bag.
"Great, solidly constructed bag - perfect for gym or travel!"
I bought this bag for two purposes: to replace my cheap gym bag and also to use as a carry on for traveling. This bag is amazing for both.For the gym, I will admit this is probably a bit bigger than I'd need. The only thing I wish this bag had was a couple of inner pockets in the main bag area so I could stash some little things that tend to float around (my GPS watch, chapstick, deodorant, etc). The interior is *quite* roomy and will definitely have enough to hold all my running gear as well as a towel and change of clothes. For traveling, this bag is excellent. It converts to a backpack which is awesome and it's super roomy, so you could definitely pack a lot into this thing. It is very solidly constructed and it can be compressed down a bit which is nice. I definitely feel like I could throw this bag around and not worry about it getting trashed. It could definitely work as a checked bag as well.
Bought it in a 45l as a gym bag and light travel bag. The shoulder straps are great although the addition of a chest strap would have been killer. When worn as a backpack, a half filled bag sits kind of weird on the back. Definitely comfortable on a short (15-30 min) approach to the climbing/camping area or a quick jaunt through the airport, but not great for an extended walk. Perfect for light travel, tons of features for the price and absolutely fantastic construction. Only had it for a little while but already put it through the ringer on my daily gym bike commute and it has held up fantastically both strapped to my front rack and strapped to my back. Will recommend!
So I've only had this bag for a little bit but I'm totally in love with it. I've used it on 2 trips plus everyday use and it really comes in handy. I bought the 45 and it works great as an additional carry-on / under the seat bag. Pretty much exactly what you'd expect from Gregory.
