This mug fits perfectly in the bottom of a 1 liter round Nalgene bottle and a 40 oz Klean Kanteen, saving valuable space in your bag. The wire handles make for easy, safe handling and keep your hands from getting burned too quickly when you stumble around camp. Stainless steel is naturally rust resistant and will withstand years of heavy use. Graduated markings help measure precise amounts of water for cooking. The mug is large enough to boil water for freeze-dried meals but small enough to drink comfortably, making it your ideal pot for quick and light travel.
