Thank you for viewing the The North Face Cassius Triclimate Jacket NP61735. ◆◆◆Product Description◆◆◆ HYVENT: Waterproof, breathable, and windproof waterproof breathable material with excellent PU coating. It shuts out snow and rain, and exhausts water vapor inside the wear to maintain optimal humidity. ●PERTEX QUANTUM: Fabric with windproof, water-repellent, and durable properties. Because it is woven with ultra-fine yarns of 20 denier or less at high density, it is very light and achieves the highest level of tear strength and seam strength by weight. ●Waterproof function ●Ventilations: In conjunction with the PAC system (Physical Active Construction), it does not hinder movement, and all models are equipped with ventilation placed in a position that can be operated without stress during activity. Even if highly breathable materials such as GORE-TEX are used, it is difficult to sufficiently control the steam caused by sweating during hard hike-ups or when the outside temperature is high and the difference in water vapor pressure with the inside of the clothes is unlikely to occur. Ventilation is essential to maintain a constant environment inside the clothes by actively exhausting steam, preventing a drop in body temperature and the accompanying decline in physical strength. ●Triclimate: 1 + 1 = 3 This is a product that allows you to enjoy it. Because it is a combination sale of a shell and an inner jacket, there are three ways to wear it. You can enjoy it in 3 ways: [Shell only], [Inner only], and [Shell and inner ZIP IN ZIP]. Inner: 20D RipStop Nylon (100% nylon) Inner padding: PRIMALOFT Eco (100% polyester) ◆◆◆Condition◆◆◆ ※Based on personal subjectivity There is some feeling of use, but I think the condition is good as there are no noticeable stains or damage. Recommended for those who like outdoor brands such as The North Face, Columbia, and Chums (^_-)-☆
