The Picture Organic Weavy 1/4 Grid Fleece Pullover is a quarter-zip fleece pullover with a reverse-grid structure, made from stretchy recycled polyester with a touch of spandex. A YKK zipper opens the front, and elastic binding finishes the collar and cuffs for a snug fit under a technical jacket. What Our Gearhead(R) Experts Are Saying:"On a long uphill hike the grid structure keeps air moving against my base layer, so I stay dry instead of clammy. The fleece still holds warmth when I stop at the top."
