The 8 Best Men’s Merino Wool T-Shirts for All Day Comfort

Best Merino Wool Shirts 00 Hero

Merino wool is a natural fiber sourced from Merino sheep. Both thinner and softer than regular wool, it’s a far cry from that itchy handmade sweater knitted by your grandmother. With a host of performance qualities — including temperature regulation, odor-resistance, and moisture-wicking — it’s actually quite the super fabric. Even still, merino wool is often second fiddle to its nylon counterpart.

With so many wool options out on the market, it can be tough to distinguish the winners from the washouts — especially when it comes to something as oft-overlooked as the humble t-shirt. But just because tees are simple doesn’t mean they can be haphazardly slapped together and brought to market. Rather, it’s precisely because of their simplicity that every thread counts. So instead of shelling out for a shirt that’ll end up in a wrinkled heap on the floor, have a look at our guide to the best merino wool shirts and grab one you’ll want to wear every day. Better yet, because it’s wool, you can — no one will notice.
