【High-Function Material】 This jacket is made of "H2No," a material developed by Patagonia that offers high breathability and waterproof performance, comparable to GORE-TEX, while being lightweight and durable. It's the perfect material for outdoor activities. 【Design】 The hooded design provides excellent protection from wind and rain. It's a simple yet functional style. 【Size and Fit】 The manufacturer's size is M, but it runs slightly large, so it likely corresponds to a Japanese size L to XL. You can wear fleece or a sweatshirt underneath without feeling constricted, allowing for a stylish fit. It generally offers a fit designed for men. The design also accommodates active movement. - Brand: Patagonia - Material: 100% Nylon - Size: M - Features: The inner hem has a function to prevent cold wind from entering. - A "RECCO" avalanche rescue system is embedded in the back of the neck. → RECCO is a rescue system created to search for people buried in the snow by an avalanche. A board weighing about 4g is sewn into the garment. It seems to use ultra-high frequency radio waves, which are relatively directional. The frequencies used are 915MHz to 917MHz and double that, 1834MHz. It searches around 915MHz, and if there's a response, it comes back doubled. The fact that it's directional means it's easy to determine the direction, and the 915MHz frequency has the characteristic of easily penetrating snow. It can reach about 5 meters in dry snow. It's said to reach up to 10 meters in snow. RECCO-equipped wear and boots are mostly top-of-the-line or flagship models, and high-end products, but RECCO itself is just a "reflector," and a dedicated radio wave transmitter is required. The searchers use a director, which uses harmonic radar to search. - Size: M - Color: Light Blue - Design: Hooded - Usage: Mountain Parka Thank you for viewing.
