The NXG Gas Canister Cover is designed to house and provide thermal protection to standard screw-top 450g gas canisters, enhancing performance all-year round. The heavy-duty lower zip provides easy access when swapping out canisters. The internal lining helps insulate the canister in cold weather and maintain a better flow of gas to your stove. Two elastic loops are positioned on the side to keep a lighter and all-important teaspoon handy when needed.
