I've haven't really decided what to put in this, but I planning to keep it in my car. And already, it's organizing stuff that I already have in my vehicle: car wash change, lip balm, spare card wallet, flashlight, pens, and charging cords. Easy enough to take with me, as I traveled this past weekend and don't leave anything in the car for theft. Also have the altitude wallet that matches. I'm a little concern with the wallet since a few cards have slipped out, but this pouch kept everything secure. The xxy zipper puts this carry case to top notch. Definitely recommend if you get the wallet.
This is the best quality pouch I found online, just wish they had a larger size one. Maybe it will manifest in the next line ;)
I use this for charger cables, etc. Great size.
