100% Wool Undershirt Bundle - 3 pack

100% Wool Undershirt Bundle - 3 pack

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. Includes three undershirts, all in Natural White.

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.

Great quality, weird design

Wool & Prince use fabric that feels great and holds up well.

I ordered these undershirts thinking that they were going to be more or less t-shirts. They're not. The neckline goes down to mid-chest and the shirt goes down to mid-thigh, making it more of a tunic.

I initially ordered a M (my typical size), then sized down to a S thinking that would fix the problem. It didn't. The description says "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." and _they mean it_.

Oh no, we're so sorry that the new fit of the undershirt isn't working for you! We'll be glad to take this feedback for improvement and are hopeful that you'll stick with us.

Cozy T-shirts

I am a convert to merino wool T-shirts. These shirts are very thin and fine and yet very cozy and warm. I wear one shirt for an entire week. Never smells like my armpits!

Overall length quite long, for a short man like me, a bit too long, but this garment was designed to fit a range of heights. Also a bit tight over my barrel shaped body.

This brand is the best I have purchased of the three brands I have bought and wear.

I hope you not running out

Best undershirt money can buy. Five days wearing it and no smell. Comfort that cotton cannot provide and smell free in five days is impressive. I hope you guys have enough of them because I am doing 100 day challenge.
Cotton is no longer on my list after trying wool.

Perfect

Amazing fit. Deep V’s are comfortable and allow your body to breathe. Not too heavy, just the right thinness. Wear it with or without an over shirt. This sucker pulls down nice and long if you want to tuck it. If you carry that’s a plus. It stacks nice too, for an above or over your belt fit. Sleeves are sized nice. Use this as a travel shirt or your everyday wear. Wash it in the shower while wearing it and air dry overnight, it’s so easy. The color is so much better than white— less stains, fades cool, and it’s 100% wool so you won’t get that nasty stank from plastic poly nylon. If you like animals you should love wearing the color of sheep wool. Can’t speak on longevity yet but I hope it holds up. Feel weird sending 100 pictures of myself to get a free shirt, however, traveling with only two shirts, this being one and the other an unbound merino, I will definitely have no problem passing that mark in this. It’s a very light comfortable shirt. Don’t worry about the negative reviews, you’ll probably like it.
