Biting bugs can ruin a backcountry trip. Since most of our hunting occurs after the frosts of fall, insects are rarely a nuisance. But when training in the off-season or even hunting in early-season those bugs can be absolutely maddening. I was one of the original testers of the Thermacell Backpacker at high elevation. The feature I like best is that it uses the same fuel canisters as our back country cook-stove so no extra weight is needed to carry this featherweight (4 oz) vampire repeller – $42 with two 24-hour mosquito repellant refills, click here to learn more.
