Patagonia Men's R1 Air Fleece Vest

The Patagonia Men's R1 Air Vest offers exceptional warmth and breathability in a package so light, you'll forget you're wearing it. This technical fleece vest is engineered for high-exertion activities in cold conditions, utilizing a unique hollow-core fabric that traps heat while allowing moisture to escape. It provides crucial core warmth without the bulk or overheating potential of a full-sleeved fleece, making it an incredibly versatile layering piece.

What It's Best Used For

This vest excels during stop-and-go adventures where regulating temperature is critical. It is an ideal midlayer for ski touring, winter trail running, alpine climbing, and cool-weather hiking. Its minimalist design also makes it a perfect core insulator under a waterproof shell for any cold, wet-weather activity where you need to move freely.

Key Features

• 100% recycled polyester jacquard fleece with hollow-core yarns offers outstanding warmth and wicking performance.
• A unique zig-zag texture efficiently moves moisture away from the body for fast-drying comfort.
• HeiQ Fresh durable odor control keeps the garment fresh through extended use.
• A zippered left-chest pocket provides secure storage for small items like a key or card.
• Two zippered handwarmer pockets are positioned to remain accessible while wearing a pack or harness.
• Offset shoulder seams sit comfortably under backpack straps, preventing chafing.
• The slim-fit profile reduces bulk and layers easily under an outer shell.

Why We Like It

What truly sets the R1 Air Vest apart from other fleece vests is its remarkable warmth-to-weight ratio and unparalleled breathability. The hollow-core yarn construction creates a lofty, air-trapping structure that provides insulation without the density of traditional fleece. During intense output, this open, zig-zag knit works like a radiator, dumping excess heat and moisture to prevent that clammy feeling. This makes it a specialist tool for athletes who need insulation during rest periods but maximum ventilation when moving fast, a balance that conventional fleece often fails to achieve.

Fabric/Material Composition

The body is constructed from 5.7-oz 100% recycled polyester jacquard fleece with hollow-core yarns and treated with HeiQ Fresh durable odor control. The pocket bags are made from 2.3-oz 100% recycled polyester warp-knit mesh. The primary fabric is certified as bluesign approved.

How It Tends to Fit

This vest features a "Slim Fit" design. It is cut to sit close to the body over a baselayer, which enhances its moisture-wicking properties and allows it to layer smoothly under a jacket without adding unnecessary bulk. The fit is athletic and tailored but allows for a full range of motion.

Sizing Availability

This product is available in Men's sizes XS through XXL.

Care Instruction

Machine wash on a cold, gentle cycle with similar colors. Tumble dry on low heat. Do not use bleach or fabric softeners, as they can inhibit the fabric's wicking capabilities. Do not iron.
