I looked at the rynoskins website. They do not say what they are made of. I personally would not buy clothing without knowing what fibers they are made of.

Maybe a cheap pair of pantyhose would be as effective! And lighter weight.

I use knee high gaiters and put rubber bands over my long sleeved shirt cuffs and wear a head net. I still get ticks on me, so checking every night is really important.

Be sure to shake out your sleeping bag, or only take the sleeping bag out of the stuff sack just before bed.

Also, when squatting to pee or poo, ticks can jump up on your bare skin.

Luckily, only my coastal hiking areas have ticks. I rarely see a tick in the high mountains.
