Filson Insulated Flannel Shirt Warm Khaki

FILSON INSULATED FLANNEL SHIRT WARM KHAKI
The Ultimate Warm, Sustainable Outdoor Layer That Doubles as a Jacket

THE LEGACY OF FILSON CRAFTSMANSHIP

For over a century, Filson has built a reputation for rugged reliability and purposeful design. The Filson Insulated Flannel Shirt continues that tradition—crafted for modern adventurers who demand comfort, warmth, and durability in one package.

This flannel isn’t just another cold-weather shirt—it’s engineered to perform like a lightweight jacket while retaining the softness and flexibility of traditional cotton flannel. Whether you’re chopping wood, hiking mountain trails, or enjoying a chilly evening outdoors, this shirt has you covered.

A FLANNEL THAT FEELS LIKE A JACKET

Unmatched Warmth and Comfort

The Filson Insulated Flannel Shirt is designed to deliver warmth without the weight. Thanks to its 6-oz. midweight cotton flannel, it provides the right balance of breathability and insulation. You’ll stay toasty on cold mornings without overheating during active use.

Durable Basketweave Design

Its basketweave construction sets it apart from typical flannels. This technique strengthens the fabric while maintaining a soft, brushed texture that feels great against the skin. Over time, it develops a worn-in character that looks better with every season.

SUSTAINABILITY AT ITS CORE: 100% RECYCLED INSULATION

Eco-Friendly Warmth

Inside, the shirt features 100% recycled polyester insulation—a high-performance material that traps body heat efficiently while staying lightweight. This insulation isn’t just warm—it’s sustainable, reducing environmental impact by repurposing post-consumer materials.

Fast-Drying and Low Maintenance

The insulation also dries quickly and resists moisture buildup, making it perfect for damp outdoor conditions. Whether you’re caught in drizzle or working up a sweat, the Filson Insulated Flannel Shirt keeps you dry and comfortable.

CLASSIC DESIGN MEETS MODERN FUNCTION

Authentic 1970s-Inspired Pattern

Modeled after the tough, outdoor shirts of the 1970s, this flannel embraces vintage style with modern materials. It’s the ideal fusion of retro design and contemporary engineering, suitable for both the trail and the town.

Functional Details Built to Last

Every button, seam, and stitch is made with purpose. The sturdy button-front closure, button-flap chest pockets, and adjustable cuffs provide practical features for daily wear. The through-quilted construction ensures even insulation distribution, preventing cold spots and maximizing comfort.

DESIGNED FOR COMFORT FROM DAY ONE

Garment-Washed Perfection

Each Filson Insulated Flannel Shirt undergoes a garment-washing process that pre-shrinks the fabric and enhances softness. The result? A shirt that feels broken-in the moment you put it on.

All-Day Comfort and Flexibility

With its relaxed fit and breathable construction, this flannel moves with you. It’s as suitable for a day on the job site as it is for lounging around the cabin.

REAL-WORLD PERFORMANCE: FIELD-TESTED RELIABILITY

Whether you’re layering it over a t-shirt or wearing it solo, the Filson Insulated Flannel Shirt adapts effortlessly to changing conditions. It performs exceptionally as:

• A work shirt on cold job sites
• A mid-layer under a waxed jacket or parka
• A casual outer layer for everyday wear

Outdoorsmen praise its rugged construction, while travelers love its lightweight packability—the perfect combination for those who live life on the go.

STYLE AND VERSATILITY

The Insulated Flannel Shirt pairs easily with jeans, canvas pants, or work trousers, making it both functional and fashionable. Its timeless plaid patterns and earthy color options suit every season, blending seamlessly into outdoor and urban wardrobes alike.

Filson Fit General: Filson clothing is known for its roomy fit, designed for maximum freedom of movement and comfort during outdoor activities. Also, the often classic, loose fit allows room to wear multiple layers, such as thermal clothing, shirts and jumpers, underneath. In addition, Filson sizes are based on US sizes, which are often slightly larger for European builds. From experience, we therefore recommend choosing Filson clothing 1 size smaller than your normal size for a better fit.

On our special FILSON FIT GUIDE page, you will find all sizes: chest, waist, hip, neck and sleeve length.
