If you bought what I think you did then you got "charcoaled" by a MIL issue MOPP suit designed for NBC warfare zones .
They make an excellent disposable form of scent containing clothing , and they work better than any commercial product that I've ever seen since they have more carbon than many of them . The ones I have , which I get from Sportsman's Guide for $15 for both jacket and pants , say that they have an average of 60 grams of unbonded activated carbon per square foot .
Basically , you wear it for up to 2 weeks when it gets cool enough to wear one and then toss it or use for insulated outerwear for awhile longer . They aren't washable , and don't really last long without frequent repair anyway since they were designed to be disposable .
