Patagonia Men's R1 Air Vest is a lightweight, technical fleece vest for men, developed for high-intensity activities in cool conditions. It provides extra warmth around the core without restricting mobility in the shoulders and arms, and works well as a mid-layer for mountain hikes, climbing, ski touring and other active outdoor pursuits.

The vest is made from 100% recycled polyester fleece with hollow fibres that wick moisture, dry quickly and offer excellent breathability. The distinctive zigzag structure increases air circulation while reducing bulk, giving a strong combination of insulation, low weight and packability.

The close-fitting cut and full zip allow freedom of movement and make it easy to regulate temperature during activity. Offset shoulder seams are strategically positioned to reduce friction and improve comfort under backpack shoulder straps.

A zip chest pocket and two front pockets provide practical storage without unnecessary bulk. Quick-drying, elastic binding around the armholes and along the lower back contributes to a comfortable and stable fit. The vest is produced at a Fair Trade Certified™ factory.
