XM-45

Product Review (submitted on May 6, 2010):

I've been using my XM-45s for touring and and commuting for a couple years now and I love the build quality and how flexible the volume is. It expands enough that I was able to pack for a 4 day camping tour with two of these and a trunk with space left over, but I can still tighten it enough to keep from flopping even when it's practically empty.
