Without a doubt the best purchase I have made on my bike since owning the bike. The bag stays in place when you're on the go, but it's just as easy to detach to carry around. I carry it on my bike almost every time I ride to hold my sunglasses, phone, insurance card, wallet, keys, etc. It actually holds up a lot more than it looks. I've even carried my iPad and accessories in this bag, along with everything I mentioned before. It doesn't damage the tank either. I just can't recommend this bag enough. Most of my buddies bought them too after seeing mine. I drive a Honda Shadow Cruiser, but it goes with almost everything.
