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.
