These bags are a nice addition to the panniers from TraX. They snug down well and seem secure. I don't expect they can handle a great deal of weight but are nice for easy access lighter weight items. My only concern is the material used for the bag. I have several Kriega bags and I wish the TraX construction was similar. Although the TraX bags come with a nice liner, a more robust waterproof zipper would be a welcomed feature. In addition, the fabric is somewhat then and although I don't have a hole in either bag, it suspect it is only a matter of time. Overall, they are a nice addition to the panniers and add convenient space. Knowing the cost would likely increase, I wish they were built from a more sturdy fabric and zipper. (Posted on 11/17/14)

i bought these bags for my sw motech side case and love them. they strap right on with little effort and stay put. the best part is they fit the 1 gallon roto pax gas cans just perfect in fact they will fix 2 in each bag stacked. even full they don't move around. they are super clean looking and the bungies on top are really useful. very impressed with them and would defiantly recommend them to any one who wants accessories but doesn't wanna drill holes in their side cases for brackets (Posted on 9/18/14)
