these are great. you can buy them in target, etc. look in the camping dept
or the place where they have lunch boxes/bags and thermos. you can get
them insulated, etc. and they come in various sizes. also, i've nice hand-made
(more expensive) ones in cutesy artisan shops. NOTE: if you freeze your
water bottle overnight and put it in the pouch, it will get the outside part
(which is against your body) wet, and therefore you and your clothes
will get wet. this is not necessarily a bad thing--just be aware of it.
