Polartec® Power Shield® Pro – These fabrics are the most weather resistant soft shell fabrics in Patagonia's alpine line. The stretchy, single layered construction is designed for the mountain enthusiast who wants a highly breathable shell with superior weather protection.

Smooth, tightly woven face for great abrasion resistance

94% polyester / 6% spandex

The membrane in the middle enables the fabric to block 99% of the wind. The remaining 1% circulates within the fabric, greatly enhancing moisture transmission and improving breathability.

Regulator Insulation – Provides phenomenal compressibility, lightweight warmth and moisture transport. This garment can be used alone or as part of a layering system.

Tricot

Regular fit – Ideal for layering underneath

Modified Y-Joint™ – This sleeve construction allows for overhead mobility without jacket ride-up. Y Joint™ sleeve construction under the arms prevents binding at the wrist or rising at the waist when the arms are extended.

Harness and pack-compatible chest pocket configuration with moisture-shedding DWR (durable water repellent) reverse-coil zippers

Pullover silhouette reduces weight and bulk for use with a climbing harness or pack waist belt.

Cuffs have low-profile closure with pleated gusset

Touch Point System™ – Embedded cord locks in the hood and hem allow for quick adjustments to seal out rain and snow.

This jacket has a helmet-compatible, 2-way-adjustable hood with a laminated visor for optimal visibility in bad conditions.

Welded Composite Seams – Patagonia's advanced stitch-free construction (patent pending) for hard shells uses a form of sonic welding, reinforced with mesh and backed by thin tape. This unique design minimizes weight and speeds dry time. Stitch free, welded seems improve the shell's performance by eliminating needle holes.
