FLYLOW Sinclair Insulated Flannel 2026/2027

Smart, Weather-Resistant Insulated Flannel for Daily Mountain Living

The Flylow Sinclair Insulated Flannel combines timeless mountain-town styling with real technical performance. Lined with a diamond-quilted interior housing 40 grams of Spaceloft™ insulation, this piece functions as a warm shirt-jacket for chilly autumn mornings, après drinks, or casual winter layering. Equipped with heavy-duty Duraflex metal snaps and warm hand-warmer pockets, the Sinclair quickly becomes an everyday wardrobe essential.

• Best For: Après-ski, mountain town casual wear, autumn chores, and casual layering.
• Why We Love It: 
• 40g Spaceloft™ Insulation: Adds lightweight warmth without the bulk of a heavy jacket.
• Diamond-Quilted Interior: Keeps insulation evenly distributed and glides effortlessly over baselayers.
• Duraflex Metal Snaps: High-durability snap closures add rugged, classic Western-inspired style.
