The road-trip essential: warm, stuffable, resistant to odor and soft enough to sleep in. 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 long center-front zipper for venting, self-fabric backing on the collar with internal neck tape for chafe-free comfort, full underarm gussets for unhindered shoulder mobility, elastic thumb loops for secure hand coverage, low-bulk merrow seams to minimize chafing, offset shoulder and side seams to lie smoothly beneath pack straps, and a drop tail for additional coverage. 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 Love it I have worn lots of zip neck tops like this and this is by far the best. While it is designed for base layer I find it is great to put over the top of a T or the like.

Rated 5 out of 5 by from Best Base Layer Ever I've been buying Patagonia base layer garments for years and I practically live in them, but you've gotten them to a whole new level with merino wool. I've worn my old capilene stuff down to rags. I'll be replacing and filling in with merino from now on. And I love what you're doing to promote and foster sustainable grazing at the base of all this. Thumbs up on all fronts and thanks.

Rated 2 out of 5 by from Good but sleeves suffer from shrinkage This is a great zip T-neck, and merino is an excellent fabric for this weight. I would rate this a five star, but there is a shrinkage factor that I noticed in the sleeves. The shirt fits true to the Patagonia sizing chart, but it does not fit quite so well after a couple washings, despite following instructions for washing.

Rated 5 out of 5 by from Excellent Base Layer! This Merino is the perfect base layer. I use it under a nano-puff vest and ski shell. Warm, dry, and comfortable. Perfect base-layer!

Rated 4 out of 5 by from Great shirt but be careful... I've had a Merino 3 top like this in the past and now have one of these newer thermal weight merinos, and I can't speak highly enough about how great this material is. This weight is great for everyday use in the winter, and its the first baselayer I reach for when gearing up for a day of backcountry skiing or resort laps. That being said, despite that care label icons saying this can be tumble dried on a low heat setting, I suspect doing that led to my shirt shrinking a bit. I'm by no means a large guy, but have to wear large in these slim fit baselayers to cover my broad shoulders and less than perfect physique, but after a few wears it suddenly went from a comfortable everyday wear to a George Costanza fresh out of the pool "Do women know about shrikage?" kind of deal. So, buyer beware and just hang dry these. I should have know better with a wool product anyway. Thankfully, the staff at Patagonia were more than happy to replace my shirt so I have a properly fitting shirt and I learned my lesson the hard way to keep the drying au naturale.
