Keep your motivation high when the temperatures really drop low. Thermal Weight is our warmest Merino baselayer. It's wonderfully soft, has a great warmth-to-weight ratio, breathes and resists odor, stretches and regulates body temperature across a wide range of conditions. Our fine merino wool is from the grasslands of Patagonia. We slow-wash it for softness and shrink resistance without the use of chlorine, then blend it with Capilene® recycled polyester for increased durability, dry times and moisture management. Features include a flat waistband with brushed inner elastic for next-to-skin softness, a gusseted crotch for mobility and low-bulk merrow seams to minimize chafing. Machine wash cold; machine dry at low temperatures.

bluesign® Approved Fabric

Patagonia has worked with bluesign technologies since 2000 to evaluate and reduce resource consumption in our materials supply chain, and to assist us with managing the chemicals, dyes and finishes used in the process. bluesign technologies, based in Switzerland, works at each step in the textile supply chain to approve chemicals, processes, materials, and products that are safe for the environment, safe for workers, and safe for the end customers.

In 2007, Patagonia became the first brand to officially join the network of bluesign® system partners.

Any fabric you see that’s bluesign® approved offers the highest level of consumer safety by employing methods and materials in their manufacture that conserve resources and minimize impacts on people and the environment.

Recycled Polyester

In 1993, we adopted fleece into our product line made from post consumer recycled (PCR) plastic soda bottles. We were the first outdoor clothing manufacturer to do so. PCR® clothing was a positive step towards a more sustainable system – one that uses fewer resources, discards less and better protects people’s health.

Today, we’re able to utilize more sources for recycled polyester and offer it on more garments such as Capilene® baselayers, shell jackets, board shorts, and fleece. We now recycle used soda bottles, unusable manufacturing waste, and worn out garments (including our own) into polyester fibers to produce many of our clothes.

Using recycled polyester lessens our dependence on petroleum as a raw material source, curbs discards and reduces toxic emissions from incinerators.

Rated 5 out of 5 by from Great Base Layer Bought this for a trip to Iceland. Kept me warm -- not too warm while out and about hiking etc. It did not get smelly even though I only had two sets of base layers for the 11 day trip. I would highly recommend this for any outdoor activity in the cold!

Rated 4 out of 5 by from Very Warm I bought these for snowboarding up in Vermont. They kept me nice and warm. I wish they were not see through! I couldve worn them for more things like fishing and commuting if they were not see through. I am 25 at 5'2. And i wear a 1-2 or 25w-26w in jeans. This baselayer fit me nice and snug. It did stop a couple inches above my ankle. Unlike the xs Capilene lightweight baselayer. Which fit but were more loose and went down all the way to my ankle.

Rated 5 out of 5 by from lovely leggings/baselayer These are lovely, the merino is soft and thick. They are warm and I wear them as a baselayer or just as leggings. I also have the thermal weight of the capilene version, and they are both great and very similar in terms of warmth. However, if you are looking for a baselayer that functions as a legging as well, then I recommend the merino over the capilene since the merino has a cleaner smoother look. The one minor complaint I would make about the merino is that the back of the waist is a little lower and sometimes I have to pull up the back of them, but this is minor. They also keep their shape well; I have a similar pair from another company that specializes in merino (and were just as expensive) and that pair stretches out during the day. Finally, I appreciate the length I'm a leggy 5'8" and a small is perfect, not short.

Rated 4 out of 5 by from Warm I bought these to replace my ancient and quite "holey" smartwool midweight merino bottoms. These are not as thick as I had hoped they would be but are warm indeed for cold winter days here in Washington state. I have worn them cross country skiing and was toasty. Next stop, alpine touring!

Rated 5 out of 5 by from Perfect cold weather performance layer! I bought this with the intention of wearing it rock climbing in the colder Fall weather and these bottoms were great! I used them as stand alone leggings when it wasn't too cold (high 50's and low 60's) and as a layering piece in the 40-50 degree weather. Super comfy, not itchy, warm, and did not constrict movement on the wall when I was wearing it as a layering piece.

Rated 4 out of 5 by from Solid leggings I've had them about a month. They haven't changed my life, but they do the job of keeping my legs warm perfectly well! I find that they slide down a bit, but that may just be me.

Rated 5 out of 5 by from Nice I love these. I bought them for backpacking as my base layer for sleeping in - I ended up wearing them when I was hiking too!! They're super warm and very comfortable. My only complaint is the same complaint I have with all wool-based products - it's very slightly itchy. 10/10, would recommend

Rated 5 out of 5 by from Comfortable and warm I purchased the Small Size. I am 5"3, 126 lbs, 27 in waist, 37 in hips. Fits snugly all over, but not tight at all. Bottom has about a 2 inch cuff when flipped up is the right length for me. If you are over 5"5, these may be too short, but again if you are wearing ski or hiking socks, a small gap won't matter. These were purchased for base layer skiing.
