What more could I ask?
You may know of flasks as being heavy, inconvenient items that don't keep your drinks hot. However, I couldn't say more the opposite about this. It fits perfectly into an ammo pouch, and for more civilian use, is small enough to fit into any bag or coat pocket. It also keeps drinks at a good temperature for an exceptional length of time. Out in rough weather on a Fieldcraft Ex, 4 hours after brewing the drink was still at a morale boosting temperature, and around 8 hours later there was still and hint of warmth. I now take this everywhere, civilian or cadet, if I need a warm drink.
