FD,
Forget about the supposed "carbon-scent control" properties of the clothing and follow a logical scent reduction routine in the first place.
Specifically, that means that you wash the clothes regularly, (ideally after every single time you hunt). The clothes should be wached in scent free-uv free soap, (their are plenty of products that are sold just for this purpose). After you dry the clothes as you pull them out of the dryer they should go straight into a sealed plastic container, (there are plenty of air tight rollable bags made specifically for this purpose the best having an air vent that allows them to be compressed and sealed.) All of the garments that you are going to hunt in should be treated this way.
Once you reach your hunting site, pull the clothes out of the bags and get dressed....then spreay your shoes, equipment, and clothes etc with a scent redcution spray...
That is the gyst of it...
