No Roll Waistband

Perfect comfort! Just the right stretch and stays put, never rolls over, and never stretches out.

Fly Front

Convinent fly front opens when you need it and stays closed when you don't.

17.5 Micron merino

Our Merino fabric is made from Australian Merino wool that is 17.5 microns. This is 1/4th the width of a human hair!

This results in the softest, most comfortable, merino wool you will ever wear! Cotton feels down right rough compared to this!

SEE WHAT OUR CUSTOMERS HAVE TO SAY

PERFECT PAIR OF UNDERWEAR

"My husband says these are the most comfortable and best underwear ever. He even asked for more. They prevent all the funk and allow all the freedom of movement. 100% recommended to anyone."

Jaime

PURE COMFORT

"I ordered two of these a few months ago and loved them so much I ordered two more pairs. This past week we had temps in the upper 90s, and yes I was wearing this wool underwear? Was I hot and sweaty? Nope! This lightweight, Merino wool breathes well and wicks away any moisture while staying dry. Stay comfy in sweltering weather! It also makes a good under layer in cool weather. It's the magic of Merino!"

Nick

ROOM TO GROW

"The comfort level of these underwear is unmatched. Enough for the crew to feel great stretch. The moisture wicking and temperature regulating qualities have the crew mission ready. Excellent product."

EASY CARE

First off, you don't need to wash your Woolx merino clothes anywhere as much as you wash cotton or synthetics.

You can wear this weeks at a time without smelling reducing waste of water and detergents not to mention time!

When you are ready to freshen up your garment just toss it in the wash on cold and tumble dry low. That's it! You'll be back in your Woolx in no time!

Can't Be Beat For Travel!

Once you travel with Merino you'll never go back. Read on to see why...

Pack less and travel light! One bag in the overhead and one under the seat. Freedom!

Avoid the lines. Once you travel without having to check luggage you'll never want to go back!

Wear weeks without laundering. Merino wool doesn't retain odors so you can wear your items weeks without laundering.

Always look sharp. Merino fabric resists wrinkles like no other fabric so take that nap on the plane.

Briefs.

I love the fabric. The medium was a bit too snug around my waist (34”). Jess very promptly helped me out with large which are much better.
