Merino wool is nature’s finest performance fabric, able to fight odor, wick moisture, regulate body temperature, and protect you from the sun’s UV rays from sunrise to sunset.

We’re not saying merino wool is magic. But we’re not saying it isn’t, because when you weave merino wool into a t-shirt, it’s a magical experience.

Merino wool t-shirts are incredibly versatile, equally comfortable in cool and warm weather. The surface repels water while simultaneously pulling moisture into its core, creating a dry body climate that cools you down in the heat and insulates you in the cold.

Merino wool is also naturally antimicrobial. Combined with its moisture-wicking properties, that means merino wool t-shirts resist odors.

There are stories of people wearing their merino t-shirt for a week without washing it, claiming it smelled just as fresh on day one as it did on day seven.

I know — magic, right?

We’re not even finished. Merino wool is naturally springy and luxuriously soft. The fabric is renewable, biodegradable, fire resistant, and hypoallergenic.

Merino t-shirts also hold their shape better and don’t stretch out, so they’re built to last longer than a cotton shirt.

In short, everyone should have a merino wool t-shirt in their wardrobe.

Here’s a list of the best merino wool t-shirts on the market, from budget-friendly buys to luxury upgrades and everything in between.

Editor’s Choice: Icebreaker Tech Lite T-Shirt

Icebreaker Merino Tech Lite

The Icebreaker Tech Lite is the perfect merino wool t-shirt for outdoor adventures. Whether you’re backpacking, mountaineering, climbing, or skiing, this premium t-shirt delivers the breathability, odor resistance, and quick-drying performance you need for a comfortable base layer.

The Tech Lite t-Shirt features Icebreaker’s core-spun fibers — nylon fibers wrapped in merino wool for optimal durability, strength, and softness. Backpackers will especially appreciate the offset shoulder seams that reduce chafing when carrying a pack.

In addition to the standard crew neck, the Tech Lite t-Shirt is also available in V-neck, patterned, and graphic print styles. We’re fans of the Tech Lite Crewe Canoe Companions T-Shirt, a fun graphic print that’s sure to get a few laughs on the trail.

Editor’s Choice: Black Diamond Rhythm Tee

Black Diamond Rhythm Tee

Wait, two Editor’s Choice awards? That’s right — both of these shirts deserve a place in your closet, because they each shine in different areas.

The Icebreaker Tech Lite T-Shirt is our favorite all-around merino wool shirt for style and versatility. But when it comes to high-output, sweaty outdoor activities, nothing beats the Black Diamond Rhythm Tee.

Built for freedom and mobility, the Rhythm Tee is the lightest technical merino wool t-shirt on the market. Thanks to Black Diamond’s NuYarn merino wool fabric, the shirt breathes better, dries 5x faster, and has 35% more stretch than your average merino shirt. So, if you’re looking for optimal sport performance while you’re sweating it out on the trail, this is it.

The Rhythm Tee was actually designed with the help of ultra athlete Joe Grant. Of the Rhythm Tee, Grant says, “I always try to choose gear that I can forget about when I’m out in the elements and that doesn’t hinder the experience. The Rhythm Tee is soft to the touch, very light and breathable, and has plenty of stretch.”

Upgrade Pick: Outlier Ultrafine Merino T-Shirt


If you’re going to splurge on a merino wool shirt, make it the Outlier Ultrafine Merino T-Shirt. Simply put, this is the finest merino wool t-shirt that money can buy.

What does this shirt offer to justify its premium price tag? For starters, the wool comes from the Mackenzie Basin in New Zealand, an area with a rich history in wool dating back two centuries. The shirts are audited and certified by AsureQuality to ensure a pristine supply chain, so you know you’re getting a pure product from the farm to the factory.

Speaking of the factory, the Ultrafine Merino T-Shirt is manufactured in the San Francisco Bay area, so you’re getting American-made quality.

The Ultrafine Merino T-Shirt features 17.5 micron merino fibers that are finer, softer, and more beautiful to the touch than standard merino. Outlier uses 195 gsm fabric instead of the standard 150-160 gsm fabric so that the shirt is more durable, drapes better, and feels more luxurious.

This shirt is geared for the fashion-conscious, featuring a moderately lean cut that’s long enough to keep you covered while you’re moving. This would be our go-to shirt for the airport and casual Fridays at the office, especially if you bike to work.

Merino 365 Short Sleeve T

Merino 365 Short Sleeve T

Most of the time, merino wool comes from a foreign commodity market. There’s nothing inherently wrong with that, but it makes it pretty unique that Merino 365 sources their merino wool directly from the farm. It’s not exactly farm to table — perhaps farm to closet?

Try on the Merino 365 Short Sleeve T and you’ll quickly notice that it’s an upgrade from your average 100% merino wool shirt. It’s made with ultrasoft New Zealand merino wool that’s noticeably more comfortable than typical merino. It also sports a trendier cut with a modern fit that looks great when you wear it.

In addition to the standard crew neck, the Merino 365 Short Sleeve T is also available in a V-neck.

Wool & Prince 100% Merino T-Shirt

Wool & Prince 100% Merino T-Shirt

The Wool & Prince 100% Merino T-Shirt was designed for wool purists who roll their eyes at the mention of synthetic blends. It features a heavier jersey fabric than the average 100% merino wool shirt, and a finer fiber size of 17.5 microns. The result is a better drape, luxurious hand feel, and improved durability.

The Wool & Prince 100% Merino T-Shirt is built for traveling, commuting, and casual Fridays at the office.

If you’re looking for a merino shirt for outdoor adventures, we’d recommend going with the standard Wool & Prince T-shirt instead. It features a merino wool blend that’s a little more durable, and it’s machine-washable (whereas the 100% Merino T-Shirt is hand wash only).
