Follow these tips for the best perfomance and longest life for your garment:


Machine wash cold inside out and Tumble dry low.


Avoid fabric softener. Though it won't damage the clothing it does coat the fibers in a wax that neutralizes many benefits of Merino.

Extreme cold requires extreme insulation.

Our ultra-heavyweight Glacier top provides intense warmth in a dense, durable fabric that's soft enough to wear next to your most sensitive skin.

Engineered for full freedom of movement without any bunching or added bulk.

The Glacier locks in heat to keep out the deep freeze.

The ideal base layer for nature’s harshest conditions.

Style #X702

Snug baselayer fit. We recommend buying your normal size for maximum performance.

"I love everything I have purchased from Woolx: Socks, everyday leggings, the heavyweight top. In fact, I ordered one pair of the Stella Everyday leggings and then reordered in another color. I ordered two pairs of socks and then reordered two more pair. I did keep the heavyweight top to one top. The idea of being able to wear things multiple days without washing appeals to me, and it works. The merino wool is the best. I highly recommend the design and feel of Woolx clothes. Excellent choice."



"After owning Woolx items you’ll never want to wear anything else! It started with a pair of Stella leggings—they are the best fitting most versatile leggings I’ve ever had. I now own multiple items and they’re all super functional, wash well, and actually look cute for everyday wear. Their clothing is an investment but I know I’ll get a lot of wear out if every thing.Their customer service is also great, and they’re very responsive to emails and on social media."



"I love the quality of the garments, free shipping, the speed at which my purchase is shipped, and the excellent communication about order status. Woolx sells well-made products at a very fair price. I live in the Great Pacific Northwest, where I wear wool year round, and I have a lot of it. Since I discovered Woolx, I’ve acquired a lit more. All of my purchases from Woolx are, without a doubt, my favorites because they are silky, soft and easy care. Perfection."

Fantastic product

Have hiked in them every weekend since January 1st, Testing woolx vs smartwool vs minus 33 vs meriwool vs icebreaker…….nothing compares to the durability of this top and bottom… the woolx brand for the heavyweight sure holds up the best, dries quickly, and doesn’t need many overlays of extra clothing….coming in a tie for woolx is the brand kora….60%yak wool and 40% merino for my backup set to the heavyweight since im starting a January 1st attempt of the Appalachian trail….very pleased and will purchase again!!!

He wears it all the time

I bought this for my husband for our trip to Europe next winter. We are planning on taking a carry-on only, so I wanted super-warm, dressy-casual layers. Woolx is perfect. Thicker and warmer than the competitors, but without the bulk of a chunky sweater. I got him the Glacier in grey and black, and the Riley for myself. So. Good. Worth every penny.

Thickest wool baselayer I could find

Most wool baselayers are 150g or 250g, but this one is 400g. It's definitely warmer. Very well made, plus I like the thumbholes to keep the sleeves from riding up when putting on outer layers. It fits fairly tight, but I wanted that so it would trap heat better. It's hard to find 100% wool baselayers--most these days are a wool/poly blend. This one is really excellent.
