Cool Backpack

Was on two bigger hikes with this already, and I quite like it, the removeable hip belts are wonderful, so I can use one backpack for everyday stuff as well as hiking. Also really love the quality of the zippers, especially at the hip belt, just so great to have it running that smooth :)

Easy access to everything without any futzing

I bought this last month and I am thoroughly impressed. I've taken it backpacking, rock climbing, and two business trips. For all uses, it was so easy to access every part of it quickly and efficiently, much better than every other bag I have ever owned. Got a rope hanging over the top of the bag? It stays secure throughout the hike, and stays in place when accessing the main part of the bag whether through top or the back panel, or even when getting into the center pocket. Backpacking? I put my foam folding pad on top, and for every other bag I've ever had, that involved taking the padd off to get into the rest of the bag, but for this bag, it stayed in place while I accessed the center pocket for snacks, or the main compartment though the top or back panel. The trip was a basic overnighter so I was not packed to the gills, but I felt like I had plenty of room even with a 20 degree bag, two days of food, a tent strapped to the bottom, and other essentials. Business trip? The bag fit a full suit with shoes, a PD wash pouch, a change of regular clothes, with a sweater over the top of the bag. Catching a flight? The shoulder straps and waist belt had so much storage I was able to quickly stow my cell, wallet, earbuds, and sunglasses. I had my computer stowed in the center pocket, making it easy to put into a separate bin for TSA, as well as grab just before tossing the bag in the overhead compartment on the flight (which it fit splendidly). I was so impressed with this bag that it prompted me to buy the 7l sling. I've only walked around with the sling for a day or so, but it seems very well designed and comfortable, especially since it attaches to the 45l bag's shoulder straps; I even fashioned it to the top of the bag like a "brain" for other backpacking bags, and excited to see how they perform when fully loaded.
