I like that it's all cotton.  Easy to throw in the wash along with my laundry, so that the bag too gets washed (I honestly don't understand how some people use bags like this to hold dirty laundry, and then put the CLEAN laundry right back in this same bag without washing the bag itself?!) ... anyway, if you attempt to use the strap around your shoulder to support the weight of the laundry, the strap WILL eventually rip away from the bag fabric itself.  (It happened to me...the strap eventually tore away from the bag, resulting in a big hole which then rendered further use of the strap pointless.)  The trick is that if you DO want to use the strap around your shoulder, that it's there as a GUIDE only, but that you still support the overall weight of the bag with your hands....
