We began making recycled polyester from plastic soda bottles in 1993–the first outdoor clothing manufacturer to transform trash into fleece. It was a positive step toward a more sustainable system–one that uses fewer resources, discards less and better protects people’s health.
WINDSTOPPER® Fabric provides total windproofness while maintaining maximum breathability to keep you comfortable in a wide range of weather conditions and activities.
WINDSTOPPER fabrics are soft and lightweight to provide insulating warmth without added weight. They allow perspiration to easily escape, which keeps you warm and dry from the inside, even when you're working hard. They’re also water resistant, and shed snow and water. Finally, they dry quickly.
WINDSTOPPER® high-performance fabrics are made by laminating a windproof membrane to the inside of a functional fabric to prevent windchill while protecting the warm yet highly sensitive microclimate that surrounds your skin. The WINDSTOPPER membrane has 1.4 billion micropores in every square inch to let water vapor from perspiration escape virtually unhindered, even when you're working at maximum intensity.
How does it work?
The WINDSTOPPER membrane is an ultrathin protective layer that is laminated to a lightweight fabric, making the fabric package totally windproof. WINDSTOPPER membrane is made from the versatile polymer PTFE (polytetrafluorethylene) which is expanded to create a microporous structure. These micropores are 900 times larger than water vapor molecules, allowing perspiration to pass through unhindered. This means that the WINDSTOPPER membrane adds total windproofness to any textile without perceivably restricting its initial breathability or weight.
Polartec® Windbloc® fabrics block 100% of the wind and provides maximum protection from the elements. The soft hand, stretch, and DWR (durable water repellent) finish combine to make this the highest quality, most comfortable windproof fleece product on the market.
Polartec Windbloc fabrics incorporate a polyurethane barrier membrane that allows moisture vapor transmission while completely blocking wind and water, eliminating the need for an additional shell. This reduces the weight and number of layers needed to protect and insulate.
Polartec Windbloc is durable, quiet, and non-pilling, and has enhanced stretch and recovery, making it ideal for activities when movement is intermittent, and when cold and inclement weather demands high-performance outer protection.
When we started making wetsuits, we quickly identified neoprene as a material that needed improvements to lessen its environment impact. So we met with the folks from Yulex who wanted to leverage the unique properties of the guayule plant, a hearty desert shrub native to the southwestern United States. Thus began a collaborative long-term project to develop a wetsuit material from guayule rubber.
Compared to traditional neoprene made from petroleum (or limestone), guayule rubber is a renewable resource that provides improved elasticity and softness and can be replaced faster than the product wears out. The agriculture is low-impact and the extraction and processing uses little energy and few chemicals.
Overall, from the crops to the rubber manufacturing, Yulex® guayule rubber has a lower environmental impact than the polychloroprene that it replaces.
Lacking fur, feathers or scales, we humans have to think up clever ways to protect ourselves from the sun. Products with the UPF designation provide built-in sun protection that won’t wear off.
To achieve sun protection, Patagonia takes a varied approach, depending on the degree of protection desired and the fabric used. Elements of the strategy can range from yarn selection to fabric construction to the use of special finishes (especially for light colors which generally provide less protection).
We use PrimaLoft® insulation inside insulated garments for its warmth, compressibility, and soft comfort. While the human body uses energy to stay warm, PrimaLoft insulation uses a patented microfiber structure to help the body retain warmth and conserve energy.
The proprietary ultra-fine fibers of PrimaLoft insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth-to-weight ratio. When insulation gets wet, it loses these air pockets and consequently, its insulating properties. PrimaLoft ultra-fine fibers were developed to be water resistant so your insulation stays drier and maintains its insulating properties even when wet.
