bottle of sawyers says it will treat 2 outfits. I used a whole bottle on one outfit, plus boots, seat cushion, and face mask, which didn't use much extra. I've worn the gear several times and only washed once. The clothes were put through a hot dryer - is that the problem? Last couple times in the woods I pulled quite a few ticks off me that had no problem getting past the clothes treated in sawyers.
