With room for the camera, memory cards, filters, brush blowers, this is why they called it a GEM.
Very well made with lots of space, its saved me taking my bum bag out for days, room for keys and phone and mesh pockets come in handy for carrying cash.
It comes with a belt to make it into a bum bag, a shoulder strap to hang it over your head and a carry handle on the top of the bag.
I find hanging it over my head and shoulder and then fastening the bum bag belt makes climbing stiles and going through tight tracks easy, the camera and case are not flying everywhere and my stuff is secure.
There are so many hidden/mesh pockets, this company should get into rucksacks.
I love it, don't think about it, buy it.
