Whether I'm in the mountains or in the city, I feel depressed when it's cold. Enduring the cold often reduces the enjoyment of the experience by half. That's why I felt the need for a vest that would keep me comfortable.\u003cbr\u003e \u003cbr\u003eWe wanted to create something that was not only warm, but also lightweight and had excellent breathability. We chose Polartec® Alpha® Direct as the material that would meet this requirement. This material is popular among many outdoor enthusiasts and professionals. We chose a slightly thicker type with a thickness of 136g\/m². This thickness provides excellent insulation even in cold environments.\u003cbr\u003e\u003cbr\u003e The moment you put this vest on over a T-shirt, you will feel your body gradually warm up. Once you experience that instant comfort, you will never want to let it go. It also has excellent breathability and moisture permeability, so it efficiently releases heat while you are active. This allows you to stay comfortable even during long periods of exercise or hiking.\u003cbr\u003e \u003cbr\u003eHowever, when you are stationary or exposed to strong winds, the breathability and moisture permeability can backfire. In such cases, you can shut out the wind by putting on a shirt or shell over the vest, and stay warmer. In this way, the ability to flexibly respond to different situations is another major attraction of this vest.\u003cbr\u003e\u003cbr\u003e The vest I am aiming for is designed to reduce stress caused by the cold and keep you as comfortable as possible in any environment.\u003cbr\u003e We hope as many people as possible will get the chance to experience this vest, which takes full advantage of the excellent performance of Polartec® Alpha® Direct, providing lightweight insulation and breathability at the same time. \u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/baseec-img-mng.akamaized.net\/apps\/item_layout\/images\/origin\/86818862\/img_cffcafeb67a591e51acc65afca0d23ca.jpg?imformat=generic\u0026amp;q=90\u0026amp;im=Resize,width=900,type=normal\" class=\"appsItemDetailCustomTag_image\"\u003e\u003c\/p\u003e\n\n\u003cp class=\"appsItemDetailCustomTag_heading\"\u003e Spec\u003c\/p\u003e\n\n\u003cp class=\"appsItemDetailCustomTag_description\"\u003e Material: Polartec® Alpha® Direct 100% polyester (136g\/m²)\u003cbr\u003e Sizes: (Men) S, M, L, XL (Women) S, M, L\u003cbr\u003e Weight: Men\/M approx. 114g \u003cbr\u003eCountry of origin: Japan Producer: Tokyo Pio Aomori Factory Co., Ltd., Tsugaru City, Aomori Prefecture \u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/baseec-img-mng.akamaized.net\/apps\/item_layout\/images\/origin\/81935218\/img_52a97cc0a5cb9b149087413aa15f0805.jpg?imformat=generic\u0026amp;q=90\u0026amp;im=Resize,width=900,type=normal\" class=\"appsItemDetailCustomTag_image\"\u003e\u003c\/p\u003e\n\n\u003cp class=\"appsItemDetailCustomTag_heading\"\u003e Material \u003c\/p\u003e\n\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/baseec-img-mng.akamaized.net\/apps\/item_layout\/images\/origin\/81935218\/img_95303775c4b2c1f613290729fc6ff815.jpg?imformat=generic\u0026amp;q=90\u0026amp;im=Resize,width=900,type=normal\" class=\"appsItemDetailCustomTag_image\"\u003e\u003cimg alt=\"\" src=\"https:\/\/base-ec2.akamaized.net\/apps\/item_layout\/images\/tmp\/img_d9df443af31d104bd6843eb3c103ef7b.jpg\" class=\"appsItemDetailCustomTag_image\"\u003e\u003c\/p\u003e\n\n\u003cp class=\"appsItemDetailCustomTag_description\"\u003e This product uses Polartec® Alpha® Direct (136g\/m²).\u003cbr\u003e\u003cbr\u003e Developed because US Special Forces needed an insulation system that could adapt to extreme temperature fluctuations and cycles of movement and rest, Polartec Alpha® was designed to provide consistent warmth while being highly breathable even when active.\u003cbr\u003e\u003cbr\u003e Polartec Alpha® Direct is an evolution of Polartec Alpha® insulation technology.
