Customer Reviews
“It is solid for an introduction frame bag. Does everything a frame bag should do. I was going to give it 4 stars because it does not have loops at the top for securing long things like tent poles or a pump but then I remembered that is is only $40! For the price, you can’t beat this one!”
“Seems to be well built! I have it mounted on a size medium Trek 1120 Backpacking bike and it fits perfectly. About a third of the cost of other competitors and seems just fine. Zippers seem decent and the material is good.”
