Anyone who enjoys the outdoors in Canada and the northernmost U.S. states knows that the real enemy of the wilderness wanderer is the malevolent black fly. Most prominent beginning in about the middle of May, and continuing to make the outdoors a miserable place to be well into June, or even July. The repelling action of essential oils, combined with the moisturizing and protective properties of vegetable oils, our 100% natural pomade (NO DEET) will protect you from those annoying Black Flies and their bites! They may swarm but they won't land!
