Flylow Irwin Men's Fleece Shirt

The Flylow Irwin Fleece Shirt blends mountain function with everyday wearability. Built with soft, midweight fleece and a button-up silhouette, it transitions seamlessly from the resort to the street.

Why we like it:

We like the Irwin for its versatility—it’s warm enough for layering under a shell, yet stylish enough for après. The classic snap-front design feels rugged but refined, making it a true four-season essential.

Features and Functions:

Midweight fleece construction traps warmth without bulk. Snap-button closure and chest pockets offer utility and everyday style. Breathable, quick-drying fabric manages moisture during active use.

Fit and Sizing:

Standard fit; designed for layering over a base or under a shell.

Bottom Line:

A dependable midlayer that looks as good off-mountain as it performs on it.
