This is a STATIC Adrift Crew. Color: Mineral Size: S (UNISEX) This item is new, only tried on. The following is quoted from the web page: ■ In recent years, the outdoor wear and active insulation categories have expanded rapidly. Mainly overseas brands have been leading the product development. Among the active insulation materials, TEIJIN Octa®CPCP® is one, known for its lightweight and high heat retention. STATIC chose to use Octa®CPCP®, which is usually used as the lining material for padded products, as a single layer. This is because products from brands that develop in high-altitude and dry climates combine Octa®CPCP® with a nylon shell material, making them heavy and difficult to layer in Japan, where they are often carried as insulation. Due to its special mesh structure, it is overwhelmingly lighter than the generally thin 300g fleece, and has a very high heat retention-to-weight ratio, making it excellent for portability and useful in all seasons. ■ PRODUCT FEATURE - A minimal fleece weighing only 110 g, eliminating unnecessary features such as zippers and hoods - Lightweight, highly breathable due to the mesh fabric, yet with high heat retention - Less likely to get stuffy even when worn during activity, reducing the number of times you need to take it on and off - Lightweight and compact, making it useful not only for the three seasons of spring, autumn, and winter, but also as a spare insulation layer for summer mountain trekking ■ PRODUCT SPEC - Fabric: Octa®CPCP® 100% polyester (53% recycled polyester) - Fit: Relaxed - Weight: 110 g (size M) - Fiber/Fabric Origin: Japan - Dyeing: Japan - Manufacturing Country: Japan ■ PRODUCT CARE - Do not use fabric softener or bleach - Hand wash or wash in a laundry net using a delicate cycle or hand wash mode - Do not tumble dry or dry clean - The fabric is weak against snags from sharp objects, so be careful when bushwhacking
