Merino Wool Tops are the warmest, best looking thermal underwear on the market today.

Our Woolx X502 merino wool thermal underwear top is the perfect thermal top to wear while you are active outside. Made from a heavier fabric than our Woolx lightweight merino wool tops, this is the perfect base layer piece to wear under a snowmobile jacket or a ski jacket. When you are heading down the Black Diamond Ski Slope out in Park City, UT you will have the range of motion you need because this is not a heavy material, but it will keep you extremely warm.

Our merino wool tops feels just like cashmere and are completely itch free, guaranteed. If for any reason you can't wear our wool because you think it itches, just return it with no issues.

The stylish look of our merino wool top means it can be worn as a regular shirt or a thermal piece. Unlike many other thermal wear brands Woolx apparel is designed with looks and performance in mind.

Comfort, warmth, style and functionality are the properties that go into every one of our garments making Woolx the obvious choice for thermal wear.

I recommend this product

Men's Explorer Long Sleeve Crew

I am an Ibex fan in slow recovery from their demise, and looking for new sources. Wool X might be it. The days of domestically made clothing of this kind may be gone, and Wool X is no exception. that aside I love the fit, the feel, and the price is reasonable, and i sense the organization has healthy work standards and practices. This shirt works if i am working on my woodpile or going to my office. Hopefully it will stand a test of time

Game changer

I was recently introduced to Woolx by a friend. I've had an amazing, non-bulky winter and didn't sacrifice any warmth. I love this brand!!!

Merino Love!

So far, I'm am super happy with this item. It keeps me warm yet dry so my body temp stays more stable and comfortable. I've worn it winter cycling and for work too. I definitely think there will be more merino in my future!

High Quality and Value

The WoolX brand promotes itself as functional gear for backpacking and hiking, so you'll hear its name uttered in the same breath as Kelty, Condor and 5.11. They don't present it as a fashion or luxury item, but there are some things that make this high-end. It has that streamlined modern fit that I'm a fan of, hugging the body. It has a bit of stretch and I don't recommend sizing up. It has narrow openings for the sleeves, waist and collar. I often find crew necks uncomfortable but this one sits just right. The fabric has a pretty good weight to it. It doesn't feel cheap or fragile. As for the value, between getting this in a clearance color and using a coupon, it was a steal. I don't know why Iceberg Navy's a clearance color. It looks good. After this experience, I'll be considering WoolX for further wool items.
