Made in the USA, the Filson Crewneck Guide sets the standard for what a sweater should be–non-bulky, with density that makes it exceptionally warm and durable. With ample stretch and outstanding breathability, this sweater would be unnoticeable to wear if not for its exceptional warmth. The rib-knit collar, cuffs and hem ensure a custom fit and retain their shape year after year. The USA-sourced wool comes from merino sheep prized for their long, fine fleece. Merino wool's wavy crimp yields a soft and sturdy fabric with natural memory and shape retention. Merino wool fibers consist of thousands of tiny filaments sheathed within overlapping scales that are naturally water-resistant, and any moisture that does penetrate the fiber is wicked to the tips for evaporation. This capillary action is what allows wool to absorb up to 30% of its own weight in water without feeling damp or clammy. The fine merino fleece is tightly spun into firm yarns before knitting, creating surprising density and a smooth, non-scratchy surface that resists pilling. Rib-knit cuffs, waist and collar provide durable shape retention for years of reliability. Sure, we could make it lighter and not so hardy, but then it wouldn’t be a Filson Crewneck Guide Sweater.
