Tough
Does what it is supposed to. Zipper is tough and tight which makes it waterproof. Large enough to store items, and compact enough to mount any where.

Wish this product came out sooner
It’s a new model and I prefer it to many if my edc pouches as it’s got more water resistance and the green/black styling makes it look less mall ninja but stuff solid functional for people who buy for use in the field. Only complaint is the yellow pull cord… replacing that with a darker color asap.

Look and feel awesome!
Size: 11.5, Color: Optic White/Opti
These are awesome shoes - look great really, really white and clean! Love how comfortable they are - and soooo light. I was a little worried they'd get dirty easily, but I've been able to keep them clean. Fit as expected. If you're looking for a great, comfortable, and affordable shoe, check these out!

Great shoe, comfort
Size: 11.5, Color: British Tan/Ivry
Love these shoes, they're super comfy. Laces stayed tied all day. I wear them in a business casual environment, or if I'm going out for a nice meal with my wife. They look good, the color is unassuming and neutral. they also elevate my height, I feel like it gives me an inch or so more versus regular shoes. This is my second pair!
