Some insects are extra persistent and try to bite you even through your clothes. For this we have the DEET-free Adventure Medical Bens Clothing & Gear Spray. It contains 0.5% permethrin to kill the little buggers on contact. The formula bonds with the fabric of your clothes and lasts for up to two weeks. So you only need to apply it to your clothes once before you leave - unless you-re off on an adventure that will take far longer than just a holiday. Each bottle contains enough for one set of gear or two outfits. Give your trip that extra bit of freedom from biting insects.
