I love these bags!  This is the 2nd pack I bought for myself and I've bought a few others as gifts.  They fold up into a convenient roll and I always have one in my bag.  They're surprisingly strong, light and roomy for how tiny they appear when they are rolled up.  I regularly use them for grocery shopping and hauling practically everything else and they've never disappointed me.  They also wash well (hang dry).  I hope people stop stealing mine bc I hate having to keep re-order them!
