Rib racer tanks are so versatile-workouts, hot day, hot date, business wear under a jacket, etc. I love the colours black, dark olive, merlot, and habour grey. All amazing.
Either stick to your original Unbound size or go up one for a looser fit. Please make this in larger sizes for those of us who aren’t thin. These tanks are for my daughters and I would love to wear a few myself.

I bought the black racer tank in L. I usually buy M in Unbound Merino but sized up as I knew it would be quite fitted. It fits perfectly without being too tight. Very comfortable. I am 5’ 5” and 140 lb. Will buy another.

Super comfortable on its own or underneath a shirt or sweater. Feels lightweight but at the same time gave a bit of extra warmth underneath a sweater in a cold rainy Pacific Northwest November day.

The Softness of Merino, Measured in Microns
The quality of Merino wool is defined by fiber diameter, measured in microns, where smaller means softer.
Unlike many Merino brands, we focus on finer Merino wool, prioritizing the softest, most refined fibers to create an experience of comfort that lasts.
Timeless Tank.
Extraordinary Performance.
- Modern neckline and flattering racerback cut made for complete ease of wear.
- Designed with added stretch for a fit that’s close to the body.
- Slim silhouette with plenty of layering potential.
- Dries fast, keeping you comfortable.
- Lightweight and packable for easy travel.
As featured in
Nature’s Miracle Fabric
Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body and acts as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

Softer Than Cotton
This wool isn’t like your typical itchy sweater. We only use superfine (17.5 micron) Merino wool, resulting in a luxuriously silky soft feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.
Natural Airflow
With Merino wool, body heat can pass through the space between its superfine, woven fibers, regulating your body temperature while keeping you cool and comfortable.
Ready-to-Go Wrinkle Resistance
A Merino wool fiber resembles a tight coiled spring, also called a crimp. Pull it and it will recoil back into shape every single time, meaning you’ll never need to iron this shirt.
EASY CARE
You won’t have to wash this item much at all. However, when it comes time for a refresh, simply add it to your load on a cold, gentle setting, then lay flat to dry.
ABOUT OUR WOOL
- Sustainably sourced from independent, cruelty-free wool farms.
- Woolmark® certified Merino wool means you can expect the highest standards related to fiber content, performance, color fastness, and dimensional stability.

The material is the best Merino wool I have owned to date. Couldn’t be happier.

Can wear a dozen times without washing. Just hang on a hook to let sweat dry and it’s as good as new. This thing is magic.

Perfect for Travel
YOU’LL PACK LIGHTER
With clothing that doesn’t smell after every use, you can pack less, allowing you to ditch the suitcase and travel with just a small backpack.
YOU’LL SAVE MONEY
These days, most airlines are going to charge you for anything other than a carry-on. Start packing lighter and doing less laundry, and save your money for the real experiences.
YOU’LL SAVE TIME
Never check luggage or worry about airports losing your stuff. With fewer but better clothes you’ll blaze through airports like a seasoned pro.
