Undershirt 100%

$74.00

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 it.

Between sizes? Go larger.

I bought a size small and it felt a smidge large. So I bought extra small and it was, in fact, too small so I took a chance and washed the size small in my machine and dried it. Now it’s prefect.

Wore 6 weeks straight. 5 days a week! And didn’t wash once. Crazy.

Holes

Arrived with 4 holes in the T shirt, so will be returning. Poor quality control.

Andre, we're so sorry to hear this! This is not the quality we'd expect from one of our shirts. Please email help@woolandprince.com so we can send out a replacement right away. Please accept our apology that your experience was less than perfect. We look forward to making it right for you.

How did I ever live without this undershirt?

Probably your worldview right now is just like mine was merely twenty-fours ago: reluctant to embrace the idea that an undershirt can change your sartorial life.

Even to those of you who are some of the new acolytes of wool, as I am, it will come as a delight to realize how revolutionary and indispensable this undershirt will prove to be for you.

What makes it so great?

First of all:

The length.

There are lots of long undershirts out there but none stay tucked with the same clam-tight resoluteness of these Wool & Prince ones.

If you stretch, it stays tucked in; if you lie down extravagantly like the dissipated monarch you feel like while wearing merino wool, it stays tucked in; if you upraise raise your arms in a stick-em-up fashion in order to demonstrate the odorless of your pits despite weeks of wear in your merino tee, it stays tucked in.

Obviously they won't shrink like dumb cotton ones, but it's more than that:

They are the exact right stretchiness.

The neck is generously open so as not to intrude clumsily into the view of an open-necked dress shirt (or even a polo or V-neck sweater or etc).

So it's the final word in undershirt style and discretion and---more than anything---totally unspoilable comfort.

It's like being encased in a layer of hygge.

If your challenging life is like mine, when you get home (and if you're lucky: when you're at work) you put on as much merino as possible. Picasso had the good sense to wear cotton-soled kung-fu slippers around his studio; add to that supreme coziness the snug warmth of merino socks [speaking of which: your'e still late with my order, W&P!] and merino underwear and merino undershirt and merino mid layer and merino sweater [how about a cardigan?] and then, when fully attired, you have got most of the more excruciating agonies of existential reality snugged out of mind.

I just got done reading THE SNOW LEOPARD, and I'm pretty sure that somewhere In those mountains is a lama who knows the ancient word for "the corporeal and spiritual comfort and joy that accrue from swathing yourself head-to-toe in Wool and Prince merino."

I don't know the word, but I know you can get it in this undershirt.

Adam, we love this review! 'It's like being encased in a layer of hygge.' High praise indeed. Thanks for sharing!

Quality, but runs large.

As my title says, sizing is my issue.
