I'm going to quote one of Scent-Lok G.Designer's posts from another thread. Hope it answers your question(s).
Scent-lok is going to seal everything off at the cuffs and ankles?
Well we are not in the business of "sealing off" scent. We adsorb scent to a point where, when taken care of, will make a person undetectable by scent wary animals. Cuffs and ankles are actually low scent emitting areas but Activated carbon gloves and Boots with GORE-TEX or Rubber boots shoulde be used in the system. Wrists, should be treated with carbon blast or some scent-eliminating spray.
Scent-lok is going to stop 100% of the odor coming off my body?
Again, we adsorb scent to a point where, when taken care of, will make a person undetectable by scent wary animals. Under no circumstances can ANY product make you completely scent free, but our system along with proper care, and the use of sprays will bring odor below a threshold that animale cannot smell.
Scent-lok is going to fully 100% "regenerate" and clean itself after throwing in a home dryer?
No we won't be 100% clean after a household drying cycle, but it frees enough carbon capicity to allow for another 40-50 hours of field use. Think of it like a sponge. You spill coffee on your counter, and begin to wipe it up until the sponge becomes full. You then go to the sink and wring out as much as you can. The sponge is NEVER fully dry, but you can soak up more coffee. This is the same thing that happens in a household dryer. You are right that it will never be able to totally regenerate it without heating it up and destroying the garment.
Scent-lok is a good solution for a week long backpack hunt?
Actually you can use it for a week by taking proper care of it. After hunting immediatly put into an airtight bag (read this as anything from a dryt bag to a garbage bag). Put it on just before hunting, and use BaseSlayers for extended hunts. If scouting wear it at the most critical points of a hunt like stalking and final approach. Lastly, and only as a last resort, put it in a black trashbag, seal it up and put it in direct sunlight for a couple of hours. Then open the bag and push any access air out and seal it back up until your hunt begins. This will allow for some extra time of activation, but should be use only as a last resort.
