It is big enough to fit all your gear but not so big that it can't fit in your front seat for example. It comes with lots of little pockets and a few velcro pockets to again, put extra gear. I personalized mine a little by purchasing some velcro and attaching patches and labels on it. A great and easy way to get your gear around and it's 5.11, so it's obviously dependable and sturdy. A patrol bag is a must have and this comes Highly Recommended.
