The national standard 90 down material meets the requirements! The highest quality across the network—distinct from market-standard products! Any inspection: if not up to standard, full refund. Welcome to request samples! #ARC’TERYX# Arcteryx System_A4.0 【Yue Dong Lan Shi】 collection KOBAH PARKA with patch logo hard shell down jacket for skiing, gender-neutral, endorsed by Wu Jianhao/Liu Wen/Liu Yuxin. “Walking Down Quilt” specialty store, large carry-on gift box, full set version, mixed-selling version. Birdia is getting smarter—last year they successfully collaborated with JILSANDER and benefited from a hunger marketing strategy. This Yue Dong Lan Shi down jacket is even more popular this year; it isn’t available in physical stores but is only sold slightly on the official website, and buyers must draw lots to get a chance to purchase! They perfectly exploit consumers’ belief that “what they can’t have always excites them.” This 【Yue Dong Lan Shi】 collection represents the fourth installment of the System series, redefining mountain-inspired aesthetics. It is also one of Birdia’s most important products for this autumn/winter season. The fluffiness level is astonishing—800! It’s called “Walking Down Quilt”. ✅ Outer fabric: 2L and 40D GORE-TEX fabrics are standard choices. But Birdia uses advanced materials like Coreloft and Polartec Power Air, creating a luxurious, windproof, waterproof, and breathable experience with optimal comfort. ✅ Craftsmanship: The Yue Dong Lan Shi series uses Birdia’s latest seamless thermal pressing technology, achieving seamless waterproofing throughout the body. Three-dimensional cutting technique ensures high fabric usage. ✅ Tags: The Gortex TEX tags for this System Yue Dong Lan Shi series use blue-tagged tags. Blue-tagged tags differ from other colors because the fabric uses a three-layer composite structure—an extra layer of warmth between layers—which is crucial for combining waterproofing with warmth and resistance to cold. ✅ Accessories: The zippers in this Yue Dong Lan Shi series use waterproof YKK5VST or YKK-grade components. The pull-tie buckles are also a highlight: they require specialized laser cutting, and the cost per pair is over 2K! Very challenging. ✅ Down: This season uses 850FP white down filling, with an astonishing 450g amount of down. The fluffiness reaches 800 level—superior to other down products like Mongolian down! It can truly be called “Walking Down Quilt”—a major competitor this year! ✅ Fit: The design features a relaxed OS fit, slightly larger than standard sizes. No restrictions during wearing. Perfect for outdoor activities without being bulky, while offering excellent warmth. Closer to the specialty store version than lower-market versions! Colors/Colour: Black, Jupiter Purple, Crystal Stone Gray, Polar White Sizes/Size: S/M/L/XL/XXL
