RE: scent killer or cover scent.....
With so many products on the market any young novice would be confused on where to begin.
Wash your hunting clothes with a good sent killing soap like Wildlife Reserach or Dead DownWind , its up to you.
Dry outside then spray them with a UV killer , after that put them in a large garbage bag ( sent free ) but if you want your clothes smelling like the woods then put alittle dirt, maybe some pine cones ,needles and acorns that kinda thing ya know.
Like I said theres alot of sent products out there from cover to attractants, you don't need a Sent Blocker Suit but they do make'em light whight and in asst. camo patterens the choice is yours to make.
