Ideal for hunters, skiers and backcountry hikers traveling in the off-season or winter, the Winnerwell Fastfold Titanium Tent Stove is the first ultralight titanium tent stove with a total weight of only 4 pounds. Recommended for use in tents and shelters compatible with fire pits. Innovative Fastfold design eliminates hardware parts and parts that can be lost or searched by cold hands. Simply fold the legs, stove walls and lid and secure with the integrated clasps. The stove folds flat for compact storage and packaging while the chimney pipe rolls into a compact tube. The Winnerwell Fastfold Titanium Tent Stove includes a 3-inch diameter chimney pipe that measures 9 feet long when fully assembled. The chimney pipe consists of a single sheet of very thin titanium that rolls lengthwise for compact and widthwise storage in a pipe. The first time you put the pipe into shape can be tricky, we recommend using a PVC hose in length and asking someone to help you. However, after the first time you burn wood in the stove, the fire will heat the shape of the titanium pipe. In later uses, the fireplace will retain the memory of the shape and blend into the shape. The Winnerwell Fastfold Titanium stove also includes a damper in the door and in the lid to control air flow and combustion rate, as well as The spark arrester features connecting points for guy lines to stabilize the chimney in windy days. With the stove lid removed, this stove works great as an ultra-light titanium Firepan for river runners and backpackers traveling to wilderness areas where a firewall is required.
