Active insulation that has been popular in recent years I will explore the reasons for being chosen
The meaning of active insulation is"Dynamic heat retention"。 Mountain climbing, trail running, etc.Heating during actionIt will be the purpose of the purpose. It is an item with a well -balanced and breathability balance that does not become too hot during action.
Characteristics of active insulation
･ ・ ・ ・ ・ ・ ・ ・ ・ It is resistant to wet, easy to dry ·lightweight ・Use synthetic fiber material
Since it is assumed to be worn during action, it is made of lightweight, resistant to sweat and wet, and is easy to dry. Even if the amount of exercise is high and the amount of exercise increases, the high breathability does not sweat at once, and it is possible to prevent sweating afterwards. Also, even when sweating or getting wet due to rain, it uses a synthetic fiber material, so it is easy to dry, and even if it gets wet, the heat retention will not be extremely reduced.
Difference from fleece and down
Many fleece are conscious of wearing while acting like active insulation, but they are easily stuffy or hard to dry.
The down is lightweight and compact and warm, but vulnerable to wet. If you wear it while sweating, the loft will collapse (the fluffy feeling will be lost), the heat retention will be lost, and it will not dry, so it will lead to cold.
