The key to its core-warming performance is 40-gram PeakFill® Active insulation—a highly breathable, quick recovery, spiral filament synthetic fill. Easily compressible into small spaces like a ski pack or running vest, it lofts back promptly when called on for treeline, ridgeline or rest-break warmth. Mechanical stretch and side-seamless construction enhance mobility and reduce layering friction. A single zip chest pocket secures a wallet and keys, while a rear drop tail and reverse coil YKK® zipper complete the fast, streamlined aesthetic.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFabric Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePeakFill™ Active Insulation\u003c\/li\u003e\n\u003cli\u003eMicrofiber with soft hand and mechanical stretch offers comfort and range of motion\u003c\/li\u003e\n\u003cli\u003eWater-repellent finish resists water and reduces dry time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStructured self collar provides additional, no-fuss coverage\u003c\/li\u003e\n\u003cli\u003eHanger loop on center back neck\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eZippers\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYKK® center front zipper with custom Stio® zipper puller\u003c\/li\u003e\n\u003cli\u003eZippered chest pocket\u003c\/li\u003e\n\u003cli\u003eZippered handwarmer pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWeight and Measurements\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRegular Fit: A casually shaped design that’s not too tight and not too baggy\u003c\/li\u003e\n\u003cli\u003eCenter Back Length: 27 1\/4\" (Size M)\u003c\/li\u003e\n\u003cli\u003eWeight: 10 oz.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOther Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHeat Transfer Stio® and Pinecone logos\u003c\/li\u003e\n\u003cli\u003eHeat transfer interior labels for comfort\u003c\/li\u003e\n\u003cli\u003eMade in Vietnam\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eShell and Lining\u003cbr\u003eRelance™ Primeflex, 50 Denier Microfiber Mechanical Stretch Plainweave, 100% Polyester,  94g\/m2 with a PFAS-Free DWR Finish\u003cbr\u003e\u003c\/strong\u003e\u003cspan\u003eRelance™, 100% polyester Primeflex™ microfibers offer improved drape, stretch and wicking properties compared to regular polyester fibers.
