Überfire is completely hydrophobic, which means it will not absorb water, so even if it gets wet, the user just needs to discard any standing water in the tin and then light it up. It is an excellent source of steady, intense heat that provides the user a means of drying out small tinder within his immediate proximity. The combustive materials in Überfire are specially formulated to assist in starting fires with whatever tinder is available, even wet tinder, and the more you fan Überfire, the hotter it gets. Überfire honors the three Ts of combustion, which are time, turbulence, and temperature. Überfire is made with all-natural, completely hydrophobic ingredients. The 2 oz. can will burn for approximately 20-30 minutes, depending on the conditions. There is a cotton pad saturated with petroleum jelly included in the tin as well. Überfire is designed to start from one spark. It will not evaporate even after partial use and can be lit multiple times. Although no synthetic materials were used in its creation, its not meant to be ingested or inhaled. Whether youre Special Forces, Military, SERE trained, Federal Agency Personnel, a pilot, an avid outdoorsman, or a hardcore bushcrafter or survivalist, Überfire is the ultimate last-resort fire option for you.
