I have this bag in grey and love it. It is extremely well made. Feels like it will last forever. I use it several times a week. It's got one small internal zipped compartment, one small external zipped compartment, and a long zipper on one side that lets you access the main compartment. Is it huge? No. I have managed to fit a water bottle, keys, wallet, chapstick, clean clothes and a gi in it, but that's maxed out and only works when you pack very efficiently...and you'll have to unpack everything to find anything. So I only use it for nogi, or a regular gym bag, or anytime I go anywhere for the day. It's a fantastic bag.
