Description

Cotopaxi's Men's Perenne Long-Sleeve Shirt is the baselayer that travels with you across seasons — "one baselayer to rule them all," as we tend to say. Simple, clean, everyday design makes it pair cleanly with anything, while a Polygiene® anti-odor treatment keeps it wearable on back-to-back days when you can't (or don't want to) wash. Made from a breathable recycled polyester and wool blend with natural temperature regulation and just-enough stretch. Wear it under a shell on cool mornings, on its own through summer evenings, or as a foundation layer under a sweater when the cold rolls in. Regular fit, soft hand feel, durable enough to take frequent wash cycles. Sized SM–2XL. Need help with sizing? Get in touch.
