A bit more gentle than the full strength Ben's 100, the Adventure Medical Kits Ben's 30 Home and Field Pack offers up to 8 hours of protection in a water based formula that, unlike alcohol based products, doesn't open up the pores to absorption of harsh chemicals. It's also less likely to dry out your skin yet still offers effective protection from ticks, mosquitoes, deer flies, and other annoying bugs. This kit contains a 4 oz. bottle for backyard, picnics, or camping, and a refillable1.25 oz. pump spray bottle for hiking.
