For anyone with prior service the canteen cup has a special place. I have used these to shave in the field, through to holding the only hot meal/drink of the week. Unlike the military issue these fit the Nalgene (which is my bottle of choice), are made of Titanium (nothing nasty here), and with the PAST logo it is sure to gain attention from others. Dave has thoroughly thought out the design with the handle actually working when the canteen is hot, unlike others on the market. I highly recommend this to others looking for a durable product that has so many uses.
