Do you mean picaridin?

I am talking about permethrin, but maybe the GP made a typo?

Here is the product that I use on my livestock:

You and GP are probably referring to the same thing. Hikers sometimes use permethrin is on clothing, not on their bodies. No clue if what you linked would be appropriate on clothes. https://en.wikipedia.org/wiki/Permethrin#Insect_repellent

Permethrin applications last multiple washings; this is also why its use can be problematic environmentally, it sticks around a long time and can hurt aquatic life. I stick to DEET on my hikes, on account of it being less damaging environmentally, but I also don't live in an especially bad area for ticks.

Permethrin for treating clothes (apply thinly and let dry for 12 hours) is usually 0.5% strength, not the 10%+ used for livestock.
