dont see how you can fit DIVING gear in it?!
for spearfishing you need only fins, mask and wet suit. there is no space for BCD and regs in this bag.
You can absolutely fit diving gear in it. The fins have their own pockets in the outside, and the rest of the bag has lots of space. I don’t have the Mako one, I have a Cressi one, and I can fit a full set of dive gear in it no problem. it’s more like a giant dry bag as opposed to the Mako.
