Why These Granite Spire Fleece Pants

The Filson Granite Spire Fleece Pants are engineered for uncompromising warmth and mobility in harsh environments. Unlike traditional fluffy fleece that wind easily cuts right through, these technical pants are built with a durable, tightly-knit exterior that actively blocks biting winds and resists abrasion on the trail.

Finished in a classic Field Olive, they are highly breathable and remarkably quick-drying, making them the ultimate active layer for cold-weather hiking, setting up camp, or wearing under waders. The soft, brushed interior provides exceptional next-to-skin comfort and thermal retention, ensuring you stay warm and dry no matter where the expedition takes you.
