mont-bell Waterproof and breathable material Storm Jacket W's S Features: This jacket is widely used for winter mountain climbing, snow mountain climbing, skiing, snowboarding, snowshoeing, and other winter mountain activities. It ensures warmth by enclosing Thinsulate, which exhibits outstanding heat retention even though it is thin, in a vest shape. Furthermore, the adoption of our unique waterproof and breathable material provides a comfortable fit with less stuffiness. A pocket is placed on the left sleeve for convenient storage of lift tickets and IC chips at ski resorts. Material Features: Super Hydro Breeze is a waterproof and breathable material independently developed by Montbell. It prevents the entry of rain particles while releasing water vapor from sweat at a very high level. Insulation: Thinsulate is a thin sheet-like batting material composed of 65% polypropylene microfibers with a diameter of 2 microns and 35% polyester yarn for maintaining strength. It retains a large amount of air between the fibers, achieving approximately twice the heat retention compared to general down or polyester cotton at the same thickness. The fiber density is high, and it also has excellent wind resistance. In addition, since the fibers themselves do not retain water, it has excellent quick-drying properties, and there is no unevenness in the batting, making maintenance such as washing easy. Notes: This product is designed to prevent water from entering the body by sealing all seams (seam tape) but due to the structure, the pockets cannot be sealed (seam tape) and water may enter the pockets through needle holes, etc. *One-owner item purchased new by myself. *All items in the first photo are included (excluding small items). *I have almost no memory of wearing it because I later purchased a Montbell Storm Cruiser Jacket M size, so it is quite clean among the outdoor gear I own, and I personally recommend it. *Cancellations, returns, and partial refunds due to buyer's circumstances such as mistakes are not possible. *Even though it is rain gear, it is not for summer mountain climbing, and it contains Thinsulate, so it has waterproof and breathable functions for winter snow and cold rain in autumn and spring, so please do not make a mistake. *It will be folded compactly, compressed, and packaged in waterproof vinyl, without bubble wrap. hokan clothing shelf
