These unique drop in liners are the same shape and size as those that may have come with your bike or those you have seen for sale but with one very important difference. Our liners unzip around three sides with opposing zippers, just like a suitcase, making packing (and unpacking) a breeze. You can see just what you have and get to it without having to drag out everything else. No more digging around in the bottom of your bag and hoping you are pulling out the item you need. Once installed in your saddlebags, top access is also easier because of the two opposing zippers. Our bags are made right here in the USA from water resistant, marine grade fabric. Our zippers are heavy duty marine grade.
