they're a great deal,
they feel thick and strong, to me. for example if I bought a Jansport daypack backpack, I would call that material thin.
this material is thick. it is like two jansports, maybe three.
noticably thicker.
thick zippers, like not on a backpack but on a super duty duffle bag. I don't know. just really thick fat zippers, too. I've used mine since I bought it, for about three months now,
superior all the way around, great utilization of light.
