I know there's plenty of tech that's gone into creating these "hydration storage devices" but there remains a major problem with them. BOILING WATER! As you all know, boiling hot water (or nearly boiling) will distort plastic. Yeah, you can wait.. wait.. wait for it to cool off enough before you fill your plastic water bottles or packs or (like Patrick Haynes mentioned a Mt. Dew Bottle), but by then your nice bed of coals is in need of tending.
Usually I go with an old kettle, my Nalgene, an accordion thingy (2 ltr.) and an aluminum 4 qt. canteen. Sadly, the big ol' canteen is gone now and I've been searching for a replacement to my old Palco 4 qt. with no success.
Short of getting someone to custom weld one up for me, does anybody have any idea where to get a canteen larger than 2 qt. and not made out of plastic?
