When I bowhunt I wear a scent-vent, it secures to anything cloth or nylon straps with a safety pin type of retainer. It screws open and closed to vary the amount of scent it omits. I use skunk, mule deer and elk depending upon what the quary is.
The skunk oil provides a good mask and I can get javelina called in pretty close, after a while you don't personally notice the skunk. So far, close but no cigar this year, poor shooting with my recurve at 3 pigs yesterday and called in a 4th, but he was too wary.
They cost about $5 and have a circular felt button inside that is replaceable with just about any type of cloth.
