Built for fast, high-output movement, the Women’s XT Series Octa Fleece Hooded Long Sleeve Top combines warmth, breathability, and packable performance in one lightweight layer. Part of our LayerOne™ Technology, it functions as a hybrid between a baselayer and midlayer — designed to sit close to the skin while wicking moisture, regulating warmth, and drying fast. The lightweight Octa® fleece structure traps air for superior warmth-to-weight efficiency without bulk, keeping you comfortable and dry when you’re working hard. A snug hood, thumbholes, and elastic-bound finishes ensure a streamlined fit for dynamic movement. XT Series is our most advanced hiking gear, taking you further, faster and lighter.
