Reviews

Love these things.

"I’ve been wearing under some Attack pants for a week in Alaska. Also in waders chasing salmon in the Kenai. I was suspect of efficacy due to super thin, but they really perform and make noticeable difference."

James F. (5/5)

Merino is forgiving.

"I have only tried these on, but my experience with merino wool says they will best if I didn’t dress warm enough. If it’s too warm, I won’t melt. Merino wool is forgiving."

Q&A

Are these meant to be worn as underwear or over underwear?
They are designed to go over underwear, but you technically could use them in place of them
