Evidence indicates too much concentration obtains if it enters the blood stream and ends up in the liver or spleen to process into harmless metabolites.
A sleeping bag could enable permethrin liberated from its bonds to the fabric by saliva, mucous, sweat and the like to enter the body.
Do not apply to inner socks, underwear, buffs, headnets, or bags that hold food, medicine, water, utensils, inner clothing and the like.
Permethrin is awesome stuff and generally safe if used properly. This means don't apply it inside unventilated spaces or touch soaked clothing items without wearing protective gloves until dry, at which point it stays bonded to the fabric unless introduced to a solvent.
It's toxic to fish, birds and other animals.
