The Ultimate Challenge: The Invisible Wall
In extreme mountain environments, climbers often face an “invisible wall.” Traditional waterproof fabrics can block wind and rain, but their lack of breathability often leads to internal condensation, causing moisture buildup against the skin. This is not just about discomfort; it is a critical safety concern for high-altitude endurance.
YJ-Shield™ TECH: Beyond the Surface
At YarnJazz, we do not just manufacture fabric; we engineer dynamic defense systems. YJ-Shield™ TECH was developed to break the compromise between protection and breathability through these core technological pillars:
Weather-Ready 2L, 3L and Beyond Engineered for the most unpredictable environments, our 2-Layer and 3-Layer Weather-Ready functional fabrics provide a versatile defense system. By integrating high-tenacity outer shells with proprietary membranes, we ensure maximum shielding without compromising on weight or agility.
Smart MVTR (Moisture Vapor Transmission Rate)
Powered by our proprietary micro-porous membrane technology, YJ-Shield™ TECH captures body heat and sweat vapor while maintaining a complete barrier against external moisture.
Eco Protection (PFAS-Free DWR) Sustainability meets performance. We utilize advanced PFAS-free DWR (Durable Water Repellent) treatments, achieving a high-grade “lotus effect” that repels water and stains while honoring our commitment to a non-toxic planet.
Precision Performance (Lamination & Coating) Achieve the ultimate balance of waterproofness and superior breathability. Through specialized precision lamination and breathable coating processes, YJ-Shield™ TECH ensures you stay dry from the inside out, even during high-intensity alpine ascents.
Data-Driven Reliability: From Lab to Peak
Every YJ-Shield™ TECH product undergoes simulations test in the Lab. From verifying 30K/30K (Waterproof/MVTR) ratings to testing performance retention after multiple washes, we provide the data to back your trust.
Future-Ready Tech
Through YJ-Shield™ TECH, we are collaborating with our global strategic partners to redefine the next generation of performance apparel, empowering explorers to focus on the summit.
YJ-Shield™ TECH：打造巔峰機能的未來
極限挑戰：那道「隱形的牆」
在極端山域環境中，攀登者常面臨一道「隱形的牆」。傳統的防水面料雖然能阻擋風雨，卻常因為透氣性不足而導致體溫調節失衡，進而造成體表汗水冷凝。 這並不只是舒適度的問題；在挑戰高海拔耐力時，這更是一個至關重要的安全疑慮。
YJ-Shield™ TECH：超越表面
在 YarnJazz，我們並不只是生產布料；我們致力於工程化出一套動態氣候防禦系統。
YJ-Shield™ TECH 技術的開發，旨在透過以下核心技術支柱，打破「防護」與「透氣」之間的矛盾：
全氣候2L 與 3L 專為變幻莫測的環境而設計，我們的2 層與3 層 全天候機能面料提供了一套全方位的防禦系統。透過將高強度表布與獨家機能薄膜結合，我們在確保極致防禦力的同時，並不犧牲服裝的輕量化與靈活性。
智慧透濕技術 (Smart MVTR) 搭載獨家微孔膜技術，YJ-Shield™ TECH 在阻絕外部水分進入的同時，能主動捕捉並排出體內的熱氣與汗水蒸汽。
永續防護科技 (PFAS-Free DWR) 性能與永續的完美交集 我們採用先進的 PFAS-free (不含氟) 持久撥水處理 (DWR)，在布料表面實現卓越的「荷葉效應」以阻隔雨水與髒汙，同時實踐我們對地球無毒永續的承諾。
精密性能工藝 (專業貼合與塗佈) 實現防水性與卓越透氣性的極致平衡。透過精密的機能貼合與透氣塗佈製程，
YJ-Shield™ TECH 確保使用者即使在高強度的登山活動中，依然能維持由內而外的絕對乾爽。
數據驅動的可靠性：從實驗室到巔峰
每一款 YJ-Shield™ TECH 產品，都必須在實驗室經歷環境模擬測試。 從 30K/30K (防水/透濕度) 的精確驗證，到多次洗滌後的性能持久性測試，我們提供完整的數據，作為您信任的基石。
預見未來科技
透過 YJ-Shield™ TECH，我們正與全球戰略夥伴共同定義次世代的機能服飾標準賦，予探險者更強大的能力，使其能夠專注於登頂的每一刻。
