The Patagonia Classic Microdini Jacket pairs a brushed fleece body with a mock neck, raglan sleeves, and a curved hip-length hem so drafts stay out and movement stays unrestricted across a full day of hiking or casual wear. Every fiber in the build is recycled polyester, with no virgin material in the construction. What Our Gearhead(R) Experts Are Saying:"This is the fleece I layer under a shell on cool-morning hikes and wear solo when the afternoon warms up. The relaxed fit gives enough room to move without feeling boxy over a baselayer."
