Ok here is the question I posed to Sawyer and the response!
Question to them from me;
I have another question for you regarding the product SP602 Permethrin spray:
If I was to treat my Buff or Bandanna with the spray and allow it to dry to the recommended time and then when I wear it, and sweat in it, is there a possibility that when the sweat comes down my face and run's into my eyes, face, and the like it will cause the harmful effect's as if I was to get the product from the spray can into those regions? I ask only because I am unsure if when the product is dry will it be inert enough that if reconstituted by sweat, rain, water, or the like, will it cause or pose any problems for the wearer of the treated garment?
Thank you for your time and have a great day,
Their response to me;
You will be fine. Just to set the record straight there is no danger posed to the human body due to direct contact with Permethrin. Even if you did contact wet Permethrin your body would break it down very quickly into harmless amino acids. The same product is used in lice shampoo at 20 times the concentration so that even when the skin disperses it there is enough left to reach the lice eggs.
All those scary warning you read on the label relate to a small amount of mineral spirits we put in the formula to get an even spread. The spirits flash off quickly but it is good not to inhale all of it. There are no warning relating to the Permethrin itself nor any concerns about skin contact wet or dry.

I sprayed pants shirt and a head net worn over an untreated Boonie. The head net provides a near heavenly respite from swarms of mosquitoes
While ticks usually find you at the ankle level (be sure to treat the socks and pants) they can also climb bushes and find you at a higher level so be sure to treat your shirt as well if you are around bushes and concerned about ticks.
I haven't done this yet
If your outdoor experience calls for you to camp out-of-doors in a nylon (synthetic) tent or under mosquito netting, be sure to treat bedding or tent netting, flaps and zippers with a Sawyer Permethrin spray to keep flying and crawling insects away at night.
Q. Is Permethrin dangerous to my skin?
A. The warning labels on the cans or bottles are often misunderstood. Your skin metabolizes, or breaks down Permethrin within fifteen minutes of contact with skin. Therefore, it is of no value to you as a personal protection insect repellent when applied to the skin. In addition, the EPA precautionary statement, "Do Not Apply to Skin" indicates that Permethrin is ineffective when applied to skin; therefore, do not apply to skin
Q. Does Permethrin work against mosquitoes?
A. Yes. Permethrin clothing treatments, when applied following Directions for Use, have been determined to have "spatial repellency" against mosquitoes. This means that mosquitoes will swarm around you, but not light on your treated clothing and bite.
Also use an EPA registered repellent, such as the Sawyer® microencapsulated Controlled Release 20% DEET, on all exposed skin for further protection from biting and blood sucking mosquitoes.

I treat everything from my shoes to my hat and everything in between and underneath. And I've not noticed any ill effects from such practice thus far, but I have noticed fewer things trying to crawl around on me, including fewer ticks in the nether regions. (Not some place you want to find a tick, believe you me.)
Before you all get your warm fuzzies and start spraying it all over your reproductive organs, remember that permethrin is a neurotoxin that kills fish and cats.
According to the Connecticut Department of Public Health, "Excessive exposure to permethrin can cause nausea, headache, muscle weakness, excessive salivation, shortness of breath, and seizures. Worker exposure to the chemical can be monitored by measurement of the urinary metabolites, while severe overdosage may be confirmed by measurement of permethrin in serum or blood plasma.
Permethrin does not present any notable genotoxicity or immunotoxicity in humans and farm animals, but is classified by the United States Environmental Protection Agency (EPA) as a likely human carcinogen, based on reproducible studies in which mice fed permethrin developed liver and lung tumors. Carcinogenic action in nasal mucosal cells due to inhalation exposure is suspected, due to observed genotoxicity in human tissue samples, and in rat livers the evidence of increased pre-neoplastic lesions raises concern over oral exposure."
Spray it all over your nether regions if you want, but I'm not gonna!
