📌Hiking Basics (Everything about Winter Hiking) 1. Tips for checking the weather (Naver Weather Search: Korea Meteorological Administration, AccuWeather, Weather Channel, Weather News 4 channels) Check the temperature: The temperature drops by 0.6 degrees per 100m in altitude. In other words, assuming a flat surface temperature of 10 degrees, it is approximately 5 degrees at 835m above sea level on the summit of Bukhansan. If the wind speed is affected, the perceived temperature will be even lower. Wind speed and gusts: I personally check the wind most sensitively. Wind speed is divided into ① average wind speed per hour and ② maximum instantaneous gust based on Windy. Personally, in the case of ① in winter and spring and autumn, if it is 3m/s or more and in the case of ②, if it is 10m/s or more, I detect it as dangerous, so I avoid hiking on mountains with open peaks. Rain forecast: Based on 5mm of precipitation, it is enough to wet your shoes even with an umbrella. 10mm is a level of rain that makes conversation difficult. Please keep this in mind when planning a hike in the rain. For reference, I tend to avoid rain of more than 5mm. Check humidity: I usually check the daily temperature range and humidity to observe the sea of ​​clouds. 2. Clothing (Overall line introduction) ① Base layer: The most basic T-shirt concept (wool or polyester recommended) ② Mid layer 1 (soft shell): Fleece made of wool or polyester Fleece: Wool or polyester material (focus on breathability) Synthetic filling (cotton jacket): Material that focuses a little more on warmth than breathability (material developed to replace down) ③ Mid layer 2 (hard shell): Gore-Tex jacket (Hard shells made of self-developed materials other than Gore-Tex material also fall into this category.) ④ Lightweight padding: Bring this optionally. (Recommended for friends who are easy to pack) ⑤ Down padding: A must-have item in your bag as a down padding with good fill power. ↪️Depending on the weather, ①~③ are generally recommended for driving (when moving). ↪️People who feel cold easily wear up to ④ for driving. +Alpha: Hiking boots and wool socks (2 layers) 3. Essential items for winter hiking Gloves: Bring 2 pairs. 1 fleece glove and 1 thick winter glove (100,000 won thick glove). Crampons: I always bring 2, but I always have at least 1 in my bag. Spats: Even if your pants can be used as spats, I think this is an essential item for Russell. Lantern: The days are short in winter. It's good to have one for emergencies. Hot pack: Bring both a regular hot pack and an attachable hot pack. You need an attachable hot pack to prevent your cell phone from dying in temperatures below -10 degrees Celsius. (Phone death within 2 hours) Cushion: You can buy a butt-sized cushion for 1,000 won at Daiso. This is a must-have item for sitting down, even for a moment. Balaclava: Search on Naver and buy Knit material hat: Any item that will keep your head warm is essential Socks: I layer 2 layers of toe socks and wool socks, and up to 3 layers in extreme winter. Hiking sticks: Hiking sticks are especially useful in winter. Gloves (2 layers): 1 base glove - 1 Reki Hikin Pro windproof glove Hot pack: Open before starting the hike and put it in the padded pocket in case your hands get cold.
