Patagonia's warmest synthetic baselayer keeps you dry and warm in cold conditions.

Weather deteriorating fast and the pitch ahead looking dubious? At least you can take solace in the warmth of this zip-neck. Soft, stretchy and compressible, our Capilene® 4 Expedition Weight baselayers are the warmest in the Capilene family. They have a smooth jersey face that glides beneath layers, and a brushed fleece interior that retains warmth, wicks perspiration and feels soft against the skin. Features include a deep zipper, a snug-fitting collar, offset shoulder seams and yoke, a zipper garage and a draft flap to help block cold. Made of 5.9-oz Polartec® Power Dry® polyester with Gladiodor® odor control for the garment.

Technology

POLARTEC® : THERMAL FABRICS The primary insulation layer among experienced outdoor enthusiasts for nearly two decades, Polartec® fabrics are available in a variety of unique textures and weights designed specifically to enhance performance in a variety of environs.

Polartec® Power Dry® Moisture and high relative humidity next to the skin cause discomfort. Polartec® Power Dry® keeps the skin dry through three complementary mechanisms:       1)  The fabric is highly breathable and does not restrict the movement of moisture vapor.       2)  "Touch points" on the fabric inner surface draw moisture. Sweat is wicked off the skin to the outside of the fabric where it spreads rapidly for evaporation. Polartec® Power Dry® fabrics move at least 30% more moisture away from the skin than single-component fabrics.       3)  When the sweat reaches the outside of the fabric, it spreads out on the outer surface of the fabric, enabling it to dry at least 2 times faster than cotton. Benefits Superior wicking action Keeps your skin dry when you sweat Highly breathable Dries quickly Comfortable next-to-skin Machine washable

Recycled Polyester: To Patagonia, quality means more than how a garment looks or functions: It also includes the way it affects the environment and quality of life. This means working to source materials and develop processes that minimize damage to the environment. In 1993, we adopted fleece into our product line made from post consumer recycled 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. Over the course of 13 years, we saved some 86 million soda bottles from the trash heap. That’s enough oil to fill the 40-gallon gas tank of the diminutive Chevy Suburban 20,000 times. Today, we're able to utilize more sources for recycled polyester and offer it on more garments such as Capilene baselayers, shell jackets and board shorts, as well as fleece. We now recycle used soda bottles, unusable second quality fabrics and worn out garments into polyester fibers to produce many of our clothes. We've also started the world's first garment recycling program – bring us your old, worn-out Capilene baselayer, Patagonia fleece or Polartec® fleece (from any maker) and we'll make a new polyester garment from it using an innovative process developed by our friends at TEJIN. Benefits of recycled polyester: Lessens dependence on oil Curbs discards, thereby prolonging landfill life and reducing toxic emissions from incinerators Helps to promote a new recycling stream for polyester clothing that is no longer wearable Creates less air, water and soil contamination
