The Men's Patagonia Synchilla Fleece Jacket features a regular fit and is constructed from 100% recycled polyester double-sided fleece with an anti-pilling finish for lasting wear and comfort. This full-zip jacket includes a zip-through, stand-up collar lined with 100% recycled polyester fleece on the inside and finished with 100% recycled nylon faille on the outside for added warmth and structure. It offers practical storage with one left-chest patch pocket and two front welt pockets, all equipped with zippers and webbing zipper pulls, and trimmed with recycled nylon faille fabric. The collar, center-front zipper, cuffs, and hem are reinforced with shape-holding, abrasion-resistant nylon binding. Set-in sleeves provide comfort when wearing a pack and contribute to the jackets overall durability.
