Are your wool items 50% nylon?

100% merino wool shrinks in the dryer, every brand. I thought I could dry my Icebreaker shirt half way in the dryer. I wore it a couple if times to see if it would stretch. I gave it to a skinny short girl, about half my weight.

78% wool socks can go in the dryer. Unless you enjoy giving away $80 shirts, keep them out of the dryer.


Do wear wool shirts on your bike tour. Do not wash them on a rainy day. The heat of your body will dry them as you cycle.

Try silk, it works, 1,000,000 chinese can not be wrong.
