I ordered two of these in black. One for myself and one for my wife. Their size and look made for the perfect to-go session Bag. The back and grey happened to match with my wife's purse, a bonus. The bag itself is unassuming and the Grav logo is hard to read from a distance, which I appreciate. I happened to leave them both in my car on a hot day, and they were full. I came back to my car after an hour and there was absolutely no odor. These bags are truly smell proof. I love them.
