Patagonia M's R1 Air Vest
Because sometimes you need your core warm and your cast unimpeded. The Patagonia M's R1® Air Vest was basically designed with anglers in mind — even if Patagonia won't admit it outright.
Lightweight, highly breathable, and quick-drying, this technical fleece core-warmer is built for cool conditions where you need to keep moving. The slim-fit, full-zip design gives you a full range of motion, while offset shoulder seams mean it plays nicely under a pack or a wading jacket. Made from 100% recycled polyester in a Fair Trade Certified™ factory.
What Makes It Work
- 100% Recycled Polyester Jacquard Fleece — Hollow-core yarns wick moisture, dry fast, and breathe exceptionally well. Warm without the sauna effect.
- Zigzag-Knit Construction — Increases airflow and minimizes bulk. It looks technical because it is.
- Slim Fit, Full Zip — Mobility-first design that layers cleanly under a shell or over a base layer.
- Offset Shoulder Seams — Sit comfortably under pack straps. No hot spots, no excuses.
- Pockets — One zippered left-chest pocket for the essentials; two front pockets with minimal zippers to keep bulk down.
- Woven Binding at Back Hem & Armholes — Quick-drying, stretchy, and fitted where it counts.
- Fair Trade Certified™ — Made in Sri Lanka by people who earned a fair premium for their work.
- Weight: 241 g (8.5 oz)
Layer it. Fish in it. Forget you’re wearing it. That’s the point.
