Carrying a roll of leather might be the only convient way to do boil water...
You're kidding right? Why would you carry a role of leather rather than a pot or a Nalgene cup or a bucket? Until recently my town had a tannery. It wasn't a place to go to buy an appliance to boil water in. Talk about leaching poisons have you ever worn new leather boots in the rain and found your socks and even your feet have turned the color of your boots. Come on, just carry a small pot. It will weigh a heck of alot less than a roll of leather and it won't poison you.
