An old friend in UK recently sent me a British Forces-issue field shirt in MTP Pattern. It's nice. Tags attached say it's treated with Permethrin and not to wash it with other clothing. Concerning.

I asked a colleague here who hikes the mountains regularly about Permethrin and told him about said garment. "Effective against mosquitoes," he told me, "but bear in mind it's a neurotoxin. I wouldn't have it next to my skin if I didn't have to."

Since my active duty days are 20 years behind me and I just wander about the hills and woods appreciating nature, now, there's no work requirement for me to wear treated clothing. Mosquitoes are here but malaria is long gone, and I'm not headed to the Middle East, ever.

Is this shirt safe to use and wear, regularly? Or is the safer bet to simply hang it up as a collectible and use something else? Thanks in advance for any guidance.
