Patagonia R1 Air Men's Jacket

Knit from an airy, breathable fleece, the Patagonia R1 Air Men's Jacket is a technical midlayer that regulates temperature better than almost anything in its class. It is light and stretchy with a full-length zip, and the lofted knit traps warmth while still letting your body breathe when you push hard.

Why we like it:

The hollow-core yarns are the clever bit, creating tiny pockets of warm air that add heat without weight.

Features and Functions:

A 5.7 ounce recycled polyester jacquard fleece forms the body, its hollow-core yarns alternating thicker warm zones with breathable open ones so it sheds heat about as fast as it holds it. A full-length zipper with a chin garage, stretchy fabric that follows your movement, and Fair Trade Certified sewing round out a genuinely versatile piece.

Fit and Sizing:

This has a trim, active cut made to move and to layer under a shell, with a true-to-size fit.

Bottom Line:

It is best as an active midlayer for cold-weather touring, resort skiing and any stop-and-go effort where you swing between hot and cold. Ideal for skiers who hate overheating.
