At 6.5 ounces (186 g, as verified on our scales) the Patagonia Specter pullover is one of the lightest woven fabric waterproof/breathable shells we’ve tested. The only same-category shell we’re aware of that may be a shade lighter is the Montane 180 Smock (manufacturer specification is 6.3 ounces, 180 g).

This article describes the Patagonia Specter's fit and styling, hood functionality and helmet compatibility, ability to layer over insulating garments, features including waterproof zipper operation and access to the kangaroo pocket, and a comprehensive description and assessment of Patagonia's new Composite Seam System, a seam construction technology based on ultrasonic seam welding. Special attention is paid to assessing and validating Patagonia's claims that the new technology is lighter, more compressible, more waterproof, and more durable, than conventionally sewn and glue laminated seams.
