>>1916144>Even those cheap butane canisters do a better job at 223 grams of gas for 330g total weight.I actually buy those cheapo butane canisters to refill a 4oz isopro canister for summer use. The 4oz's is good enough for 2-3 day trips, and and since you're refilling it, you never have to carry a half-empty canister
