Snow Peak's fire-resistant down jacket. The size is the smallest, 1 (equivalent to SS). I opened it once, but it's unused. - Color: Black - Size: 1 (equivalent to SS) Shoulder Width/Body Width/Sleeve Length/Length Shoulder Width: 50cm Body Width: 59cm Sleeve Length: 58cm Length: 70.5cm (Quoted from the manufacturer's website below) This high-spec down jacket uses 800 fill power down to handle extremely cold fields, and the water-repellent treatment maintains high heat retention even when wet. Furthermore, it is practical as it can be washed at home. The outer fabric uses a 2-layer original material that combines flame resistance and waterproofness. The base fabric uses a yarn that blends natural-textured polyester spun and high-strength aramid fiber "Kevlar," and recycled PET bottle yarn is used for the polyester part, considering the environment. Toray's "DERMIZAX," which has excellent moisture permeability and waterproofness, is used for the membrane, and a C0 water-repellent treatment with a low environmental impact is applied, making it comfortable even in bad weather. A lightweight and supple 20-denier material is used for the lining. It is flame-resistant, so it can be used for campfires, and it is also waterproof, making it a strong outer jacket against rain and wind. It is a versatile piece that can be used not only for winter camping and outdoor activities but also in everyday situations. *The seams are not waterproofed, so water may penetrate in heavy rain. The silhouette allows room for thick knitwear and mid-layers, and ease of movement is also considered. The three-dimensional design of the sleeves eliminates the difficulty of movement typical of down jackets and allows for smooth arm movement. The chest has large and small pockets arranged separately, one above the other. The side pockets have double zipper sliders for improved convenience, and the use of brushed material for the pocket bags also functions as warm pockets. A large pocket on the inside of the left body can store bulky items such as gloves. It is also ideal for storing items that are sensitive to cold, such as smartphones and camera batteries. The hem and hood have adjusters to prevent wind from entering. The cuffs are made of rubber and Velcro for easy sleeve rolling and can be adjusted to your liking. Furthermore, the design does not expose the stitching on the outer fabric, reducing water penetration from the seams and suppressing cold spots. It has a chin guard that is gentle on the face line, providing a comfortable fit. Thank you for viewing.
