I'm wondering if anyone has come up with a simple effective way to carry and refill your daily water supply as you go. I'm not talking about what you might do when you stop at night or what have you. More what you do to keep a running water supply going, w/o having to say fill up a 70 liter bladder or whopping bottle at the start of the day and lug it around.
That sort of thing seems like such a waste when there's water all around to be had. I've been experimenting with keeping various wide mouthed containers half full of snow, with a bit of water, on my pack exposed to any sun at all times. If there's no sun or it's really cold I'll slap a hot hands type of product on the bottle to help melt the snow.
It mostly is working out okay, the part I'm unhappy with is what container to use and how to best fasten it to the pack so it's not in the way but still exposed to the sun and easy to grab. The damn naglene containers seem to be made to be in your way. I've found some bladder/canteens at REI that seem a bit better but am still fussing with some good way to fasten it to the pack as I desire.
Interested in your experiences with this or any ideas.
