LL Bean vs Insect Shield permethrin clothes - how many washes?
I’m a little confused because Insect Shields website says the permethrin lasts as long as the clothes, but LL Beans website says it lasts 70 washes.
But if you buy it yourself and spray your clothes it only lasts 20 washes?
I’m assuming they’re treated the same, and maybe only last around 20 washes?
