If you need a larger than most bag that won't keep you checking it's position in your rearview, this is the bag for you! With so many mounting options, this bag isn't going anywhere. As a dry bag, it can be compressed down, but also includes a top flap to secure additional items on the exterior. We use this feature for securing tents, groceries, or even our extra layers without having to go though the hassle of making extra space in the main bag. Heavy duty construction means this bag will last even the most trying of riding conditions. A great travel bag, the only downside will be having to carry all your friends stuff that won't pack into their bags!
