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.

Repeat customer - big fan of WoolX clothing!

This was my 4th Woolx item. Excellent merino wool top. Very soft. Real good quality. Sizing runs a tad big. Please offer tops in XS. Outstanding product overall! Definitely recommend.

Another great shirt

Since discovering wool shirts for my everyday wear I was in the market for another long sleeve tee. This was on sale and shown as mid weight. Couldn't pass up the deal and the color was ok so I went for it. Very nice product, fit was as expected and shirt was smooth and soft. The torso length is pretty long from what I'm used to but tucked in it will not pull up. Cuffs are snug and overall I really like this shirt. Another excellent wool shirt. Definitely buy again....in a different color.
