On a recent trip to Ontario during the height of the mosquito season, four of us agreed Insect Shield kept the bugs at bay. Treated with Permethrin, a natural insect repellant, Insect Shield's wide array of garments repel ticks, mosquitos and flies. The treatment lasts through 70 launderings and is safe for all ages to wear. Be aware that you should use a traditional insect repellant to protect areas of exposed skin.—Amber Pratt
