Patagonia’s Isthmus earflap cap sits in that sweet spot between functional winter gear and slightly quirky outdoors style because it blends real use with a style that feels a bit unexpected. The earflaps, the short brim and the soft lining all come from practical cold‑weather design, but the shape has that off‑beat, retro‑outdoors look that’s resurfacing in winter accessories. 100% Recycled Nylon Ripstop, Fleece Lining, 5-Panel Cap, Snap-Secured Ear Flaps, Adjustable Back Strap, Woven Branding, Style Code: 33531-INBK, Patagonia, - Patagonia Men's Isthmus Earflap Cap Ink Black Colour: black
