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.

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.

Had an issue with this order never reaching us, but Drake helped us get a replacement order issued and delivered very quickly.

Quality is top notch, and saves a ton on laundry to keep your nice clothes clean. Thank you!

warm, yet silky, soft merino wool men's undershirts

I just received my second three pack order for my tall, thin husband who needs to keep his core warm to be comfortable.. He wears them from early fall to late spring and loves the warm, yet silky, merino wool. The v-neck is perfectly cut not to show under a button-down shirt . The undershirts wash beautifully in my washing machine with warm water setting. I partially dry them on medium heat in the dryer and then lay them on a flat surface to block them while still damp. Like nearly all men's undershirts I have washed over the years, the seam at the bottom right of the shirt twists a little after washing. By blocking the shirts in order to square up the seams, the shirts dry perfectly flat and fold to look like they just came out of the original packaging. (BTW, I put my partially dry linen sheets on the bed and smooth them our as well and they look ironed once dry.) Definitely worth the price and the minimal extra effort to block.

Too Large

I wear medium everything, but this is too long and tight.
