최고의 메리노 울 의류(2026): 베이스 레이어, 후드티, 재킷 등

Merino wool is a super fiber. The best merino wool clothing somehow manages to be comfortable in 95-degree heat, and merino base layers keep you warm well below freezing. Unlike synthetic fibers derived from petroleum, merino wool is natural and renewable. Merino wool’s versatility means there’s a bewildering array of blends and options. Here are our favorite merino wool products that we've tested by wearing and washing (usually in cold water, and hung to dry, although we do machine dry them just to see what happens) over the course of months and even years in some cases. Once you're done here, check out the rest of our apparel guides, like the Best Merino Wool T-Shirts, Best Base Layers, Best Puffer Jackets, Best Hoodies, and Best Hiking Boots. Updated April 2026: We've changed out top pick boxers to Wool&Prince, and added more hoodies and the Ibex women's Goat short sleeve. We also updated prices and links throughout. Why Is Merino Wool So Great? Merino wool is great because you're stealing a sheep's ability to keep itself warm or cool based on the temperatures it's in, a process often referred to as thermoregulation. If you've only ever worn the sort of itchy wool sweaters your proverbial grandmother supposedly made, you might wonder what all the fuss is. The answer is that Merino sheep have thinner, softer wool, which has evolved to keep them comfortable across a wide range of temperatures and is comfortable to wear next to your skin. Wool is sustainable, too. One sheep can produce 4 to 5 pounds of wool per year. That's because the sheep that make merino wool drink only the purest alpine waters and study the art of comfort under the tutelage of those stuck-up Pashmina goats, who, let's face it, might know a thing or two about wonderfully pillowy softness. Just kidding. Merino sheep do have that softer wool though, and merino wool is a remarkable fabric that's become the cornerstone of my wardrobe. What Does GSM Mean? Merino wool comes in different weights, which you will frequently see listed as “200 gsm” or something similar. (The “gsm” refers to grams per square meter, sometimes listed as g/m.) What's important is the scale and where your garment falls on it. At the low end, you have T-shirts and underwear, which are typically 150 gsm, though we have seen some as low as 120 gsm. Generally, anything below 200 gsm will be a good base layer or T-shirt. From 200 to 300 gsm are your mid layers, and anything above 300 is a heavier garment. If you're more familiar with synthetic ratings like those often used on fleece, know that, in my experience, about 120–160 gsm wool corresponds to 100-weight fleece, 160–200 gsm wool roughly matches 200-weight fleece and 200+ wool is like 300-weight fleece. In every instance, the wool is warmer because it's better at trapping heat, especially in the wind. (That said, there are reasons to go with fleece at times, like how incredibly lightweight it can be.) What Is Nuyarn? Nuyarn is a merino wool/synthetic hybrid weave, wherein merino wool is wrapped around a nylon core for warmth, lightness, and extra durability. The idea is to get the temperature regulation benefits of merino, but to add some of the longevity of nylon. In my experience, Nuyarn mostly works. It's our top pick for base layers, though I find it less necessary in more casual garments, where I prefer 100 percent wool. How to Care for Merino Wool Most merino products will have care instructions. Most likely it will be to wash cold and lay flat to dry. The latter is important, as hanging wool to dry will stretch it out (because of the water weight). While most merino labels say the garment can be machine washed, my experience has been that hand-washing merino will extend its life. This is particularly true of very lightweight (150 gsm) merino base layers and T-shirts. The exception is Minus33's Microweight Raglan short sleeve T-shirt, which is machine-washable and dryer-friendly. Having done both to mine for over a year, I can vouch that it does indeed hold up. I've never had a problem storing merino in my closet between wears, but for long-term storage, I recommend you take precautions against moths, which are notorious for eating holes in wool. I have lost merino garments to moths. If you don't want to smell like mothballs, there are better solutions. I make sure to wash and thoroughly dry whatever I am storing, then I seal it in a compression bag, like this. Another option is to put your merino garment in a cotton bag or otherwise wrap it in cotton and then put it in a plastic bin. It's very important to make sure that the garment is completely dry before using any of these storage methods, otherwise your wool will smell musty and moldy. Other options include storing your garment in a cedar chest, which is a good natural deterrent for moths, or use moth traps or lavender sachets, which will repel the moths. 100 Percent Merino vs. Blends Should you buy 100 percent merino or should you go for a blend?
