NOT YOUR GRANDMA'S WOOL SWEATER

"FEELS LIKE WEARING NOTHING"

We know what you’re thinking… How can wool underwear possibly be comfortable? It's because it is merino wool underwear!  “Itchy” wool has a course texture and 1 to 2 crimps per fiber.  Merino wool is very fine and has up to 100 crimps per a fiber, making it soft and silky against your skin.  

We use “superfine” merino in all of our products measuring 17 microns in thickness. To put that in perspective, a strand of human hair is between 60 and 180 microns thick, so BRANWYN merino is up to 10x finer than your hair! 

Combine those  facts with merino’s unparalleled strength and elasticity, anti moisture and anti microbial properties, and you have the best women's active underwear ever.

Testimonials

I wore these undies for the MS150 ride and I am so glad I did. Zero chaffing after 162  miles in the Colorado heat!

Melissa

They make me realize how important a great pair of underwear is to staying true to myself. No more getting my “granny” panties all in a bunch over uncomfortable underwear!

Mary

Most comfortable bra I've ever worn! I've tried other wool bras and this one is my favorite by far.
