Living in Guatemala this summer in a place with no, repeat no, hot water. Can't even get lukewarm in the tap. Interesting discovery that the 2 creams I have with me (T&H West Indian Limes and AOS Unscented) and the soap (Classic Shaving wool fat Tea Tree) do almost as well in cold water, using just a small travel brush and my palm. I am probably using a touch more product to compensate, but the lather is +/- 95% as good as with hot water. I always figured that cold water was the kiss of death for lathering and/or shaving, but it is really not that much different.
