Stonepeak Lightweight Performance Flannel Shirt – Men’s

What Our Gearhead® Experts Are Saying:

“I’ve been wearing the Stonepeak Lightweight Performance Flannel on fall hikes and travel days—it’s breathable, warm, and looks clean enough to wear straight into town. The hidden zip pocket is a nice bonus for stashing a card or key.”

We love a flannel that looks casual but performs like a technical layer, and the Marmot Stonepeak Lightweight Performance Flannel LS checks all the boxes. It combines the soft feel of brushed cotton with temperature-regulating THERMOLITE EcoMade fibers, giving us just the right warmth for active days in cooler weather.

The lightweight construction keeps it breathable when we’re moving, while the classic snap-closure design and shirttail hem maintain a clean silhouette. A single chest pocket features a hidden zip compartment—ideal for stashing a key, ID, or trail pass—making this flannel as functional as it is comfortable.
