Fathom Tech Flannel - Men's Long Sleeve Shirt

The Fathom LS Tech Flannel is a men’s technical shirt that reworks the traditional plaid shirt with a design built for the outdoors and fishing. Its Black Grey pattern gives it a clean, versatile style that’s easy to wear both by the water and day to day.

Made from a 165g/m² twill fabric blending polyester and elastane, it offers a solid balance of durability, comfort, and freedom of movement. Its DWR water-repellent treatment helps handle light moisture, while the two-way stretch fabric moves naturally with you.

An outdoor shirt that’s as functional as it is versatile

With the Fathom LS Tech Flannel, the classic look of a plaid shirt meets a more technical build. Its stretch fabric gives you the ease you need when you’re on the move, while the DWR treatment is a real plus when conditions get slightly damp.

Originally designed as a technical fishing shirt, it easily fits into an outdoor outfit, travel kit, or everyday rotation. Worn on its own or layered up when temperatures drop, the Fathom offers a more functional alternative to a traditional flannel shirt.
