i use scent killer when i cant find dead down wind. i like the fact it says it works for days after drying...i noticed my hunting clothes dont have that smell they usually carry...like wet, dirt, fall rotting leaves wierd kinda smell. this year i started carring about scent. dont know if scent away is diffrent or not. i rather use the scent removers then go out smelling like dirt, an acornor pine tree etc.....just my opinion...just seems that youll smell prettttty strong if you spray yourself down good
