The new single stove for mountaineering is lightweight and compact, building on the ST-310 and ST-340 models. It’s 59% lighter and 42% smaller than the ST-310, making it easier to carry and pack. It features a mortar-shaped fire mouth for wind resistance and a titanium trowel to reduce weight and the risk of burns. The stove includes a stainless steel ignition assist lever and a minimal heat shield for safety. The new three-stick design allows for slimmer storage, and the Tyvek pouch is durable, water-resistant, and safe. Made in Japan.
