A decent snorkeling bag for the price, BUT certainly not a snorkeling "backpack"! It has only one shoulder strap. This strap is centered in the middle, resulting in not very well balanced carrying, neither when carrying on one shoulder nor crossed around the neck (two D-rings at the bottom corners and a snap on the strap would have solved the issue… well, or actually adding a second strap…). Also, the strap is not padded (which I actually kind of like, because of weight issues). Carrying the bag for short distances is not a problem, but I was looking for an actual backpack comfortable enough for longer hikes and/or difficult terrain. So, I was pretty disappointed at first. However, there is a quick fix to the problem: A strap (or belt) around the waist plus the lower part of the bag stabilizes it quite well; that way I can also comfortably carry two of these bags (for gf and myself) with one on each shoulder. So, while "backpack" is a bit of false advertising, in the end, I was still happy with the buy.
Other than that: The construction overall seems to be a very good compromise between light weight and sturdy (time will tell about the latter, as the emphasis is certainly on the former). The bag should hold fins up to ~27 inch long. It comfortably holds my pair of regular size Aeris Mako fins (24 in) with 3 mm ankle booties in their foot pockets. There seems to be just enough room for an additional regular sized towel (not for a large beach towel), a book (again, not oversized), your mask/snorkel, and maybe a small/medium water bottle (and these items would need to be distributed between the fin compartment and the smaller additional compartment; note that both compartments include mesh for drying, and that there is no "dry compartment"). This is probably all the weight you would want to carry in this light bag anyway. Size and weight seem ideal for my needs of a snorkeling bag (if I need to carry more stuff than indicated above, I use a larger mesh backpack for scuba gear).
