Primus Winter Gas 230g Canister Vapor Mesh Cold Weather Butane Propane Blend

Are you planning to use your butane appliances in colder weather?  Primus Winter Gas is a great solution!  Designed for use in cold temperatures, it has technology that increases the liquid fuel vaporizing to a gas, which means higher pressure and a stronger flame.  Plus, the gas pressure in the canister increases as the fuel is used.  Primus butane canisters use an approximately 20% Propane and 80% Isobutane mix. IMPORTANT NOTE: Federal DOT and USPS regulations allow us to ship up to 1 liter (33.6 fl oz) of fuel per single package.  For example, you can purchase up to eight 110g canisters (8 x 3.9 oz = 31.2 oz), so 9 would be over the limit.  Yes, you can mix and match! So you could purchase one 450g (15.8 oz) canister, one 230g (8.1 oz), and two 110g (3.9 oz).  The math is 15.8 + 8.1 + 3.9 + 3.9 = 31.7 oz, which is under the 33.6 oz limit.
