Title: VERY Impressive Heat Capacity!
Review: Wow! BOILING hot water first, then poured in as much steaming tea as I could... Stayed hot all day at work, and even into the night once I got home. We are talking a period of over twelve hours. Color me absolutely impressed, floored even. Amazing thermos.Note that this thing is about a foot tall, so don't expect it to tuck into the side of your hiking pack... but should fit into the main compartment of most 24 hour packs just fine.
