Designed to strike the optimal balance between weather protection and breathability, Power Shield Pro offers the best soft-shell weather resistance without compromise to breathability. We specifically designed these shells to meet the needs of our athlete team and our most technical core customers. Polartec Power Shield Pro combines never before seen levels of air permeability with durable hydrostatic resistance to keep you dry both from within and from out.
How does it work?
Polartec Power Shield Pro fabrics feature a smooth, tightly woven face for great abrasion resistance, and a polyester back for a high warmth-to-weight ratio. The membrane in the middle enables the fabric to block 99% of the wind. The remaining 1% circulates within the fabric which greatly enhances moisture vapor transmission, improving breathability and reducing the risk of heat stress buildup. Polartec Power Shield fabrics have the best breathability in the soft shell market. In fact, Polartec Power Shield Pro fabrics are 30-50% more breathable than windproof soft shells in dynamic or active conditions.
Highly Breathable and Highly Water-Resistant
The biggest advance of the new Polartec Power Shield Pro membrane is the addition of real water resistance, measured through a hydrostatic head. Polartec Power Shield Pro delivers an initial 5,000mm hydrohead (ISO 811, AATCC 127) and remains durably water resistant to a minimum of 3,000mm for life. This level of water resistance exceeds the requirement for seam sealing on a waterproof breathable shell (3psi or 2100mm) so you can be assured of its performance. The combination of water resistance and breathability of Polartec Power Shield Pro offers a great advance in soft shell comfort.
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.
