Undershirt 100%

Undershirt 100%

We don’t make bold claims lightly, but you’re looking at the first ever thoughtfully designed undershirt made from 100% merino wool. Our undershirt has two critical improvements: a long, snug torso for best-in-class “stays-tucked-in” fit and a wider/longer v-neck opening to hide the undershirt from “peeking out”. Pair that with our super-soft, custom developed merino fabric, and you’ve got yourself—another bold claim coming at you—the best undershirt on the market. It’s so comfortable that you might just sleep in it.

Not an ordinary undershirt

Wool is always best next-to-skin, and now there’s another way to wear it. These pieces are specially designed to go unnoticed and stay tucked in all day. Get even more wears out of your button-down wearing an undershirt. Available in two distinct fabrics.

Power-up your other shirts

I got this undershirt because I have a number of non-merino world shirts (both cotton and synthetic). This shirt confers some of the advantages of wool to these shirts by having merino next to skin. It feels great and doesn’t show through. On trips, I’ve used for several days in a row and as a night shirt with no hint of smell. We’ll see how it works in summer as I’ve only had it for the winter so far.

Disappointing due to odor

There's a lot to like about this undershirt... it's soft, good fit, good length, I like the V-neck.

Unfortunately, I can only get one wear out of it before the pits smell. I have other merino wool garments (like Smartwool socks) that I can get several wears out of before they smell, and my W&P button down has been great for a dozen wears (over an undershirt), still very crisp looking.

But for 80$ I expected a merino wool undershirt I could wear at least a few times before it started to stink.

I don't wear deodorant so that could contribute, but it also means there should be no chemical build up around the pits preventing merino wool from doing its odor absorption.

Also, I once accidentally put the shirt in the dryer instead of air-drying...maybe that denatured something and ruined the odor eliminating properties?

Or maybe deodorant is the answer...idk. I don't put deodorant on my feet, and the smartwool socks don't seem to need anything to stop them from not smelling.

Started Strong

I bought one to try as a regular undershirt for when I wear a suit.

The good:

Feels great and does not stink due to the merino makeup of the shirt.

The Bad:

In less than a year it has developed 5 small holes in the front of the shirt just under the chest. The shirt has been washed one time folllowing the instructions.

Chemical smell

I washed my shirt three times already and they have a very strong chemical odor. I wish I never bought them. Very disappointed. They smell really bad.
