As I said before, the front pocket zips are waterproof and, very importantly in my opinion, you can easily grab them. Their size is #10, and a small braided zipper makes them easier to open and close. It may seem like a detail to you, but waterproof zips are often more difficult to slide than traditional zips. Are these zippers welcome? . I did not open the bag to check, but I feel that a rigid foam is integrated into the back. Thus, the bag remains straight and the weight of the bag remains pressed against me when I carry it. On the other hand, this bag has 4 compression straps. For a 32L it is, in my opinion, essential. Their buckle system is clever because it allows the straps not to drag anywhere. It's a detail, but when I'm cycling with a bag on my back, I like that its volume remains compact.

The sternum strap moves easily over the shoulder straps and, like the compression straps, adjusts very easily. North St. has found the right compromise between the plastic buckles and the straps used, making them easy to grip and easy to adjust.
Despite the fact that the back is straight, it is made of thick foam and a mesh that allows a certain breathability. To understand the importance of back shape, compression straps and sternal strap, take a look at this article? . The lifting handle is made of a strap sewn on foam a few centimeters thick. Its touch is very soft, almost fluffy (which will please the most fetishists among you ^^). Inside are female scratch strips in 50 mm. North St. offers additional pockets to attach to these bands. Personally, I'm not a big fan of modular bags. I prefer to have a solution imposed on me. But, if you wish, you can even customize the interior and take advantage of these strips to attach whatever you want. Against the back is a computer compartment, in which I easily slide my 15 inch (with its cover). The elastic strap is nice because it presses your computer well against your back and it's easier to use than a strap with a scratch.
