Cirrus Shirtjac

(No reviews yet) Write a Review


When you come across a fabric as ridiculously soft, stretchy and breathable as this micro–nylon weave, you generally want to keep it near you at all times. Our Cirrus Shirtjac is an easy, versatile and reliable throw–on piece that’ll serve you well season after season. The mechanical stretch shell and coiled yarn stretch insulation provide four–way movement for active exploring, yet the shirtjac doesn’t look or feel like a “techy” performance piece. DWR–treated for weather resistance and it packs down into its own pocket, handy when you step off the tarmac and into the tavern.
