DH & I have started walking in a nearby local park & take a water bottle with us. He has a little contraption that he put together to belt around his waist & holds 2 bottles. I looked online to see about making one for myself (as I've seen tutorials posted on how to make them) and ran across this brilliant idea. The only draw back is that it is not encased & would not stay cool but I could slip it into a little koozie that would help. I really like the one that clips to your belt loop.
For those who are looking for craft show items or stocking stuffers or really simple gifts, I think these would work wonderfully.
