Why did the Free Arm Jacket change its name from 'Rain Jacket' to 'Layer Jacket'?
It is difficult to tell from the product description alone whether it was originally designed as rainwear or as an everyday outerwear garment. I would like to know what differences arose in the garment's use or functionality when the name changed.
POSTALCO explains that it uses an in-house fabric that combines water-repellent performance to bounce off rain with UV protection, making it an outer garment for layering regardless of the season.
It was originally a rain jacket worn to avoid the rain, but starting in autumn/winter 2022, its name was changed to layer jacket, meaning a garment for layering[1]. Looking at the properties of the fabric used in the jacket provides clues as to why the name changed. The Shear Dry Nylon used in the garment is an original water-repellent fabric developed in-house by POSTALCO[2]. In addition to water-repellent processing that bounces off water droplets, it also features 95% UV protection performance[3][4].
It is not a garment solely for keeping out rain. It can be thrown on effortlessly not only on pouring rainy days, but also on days when the sun beats down or a chilly wind blows. Generally, thin nylon outerwear that combines both water repellency and UV protection is widely used as a layering outer garment to maintain body temperature during seasons with frequent weather changes.
hmmm, removing 'Rain', which tied the garment's use to specific weather, and adding 'Layer' highlights its role as an outer layer that can be worn over other clothes at any time in daily life, regardless of bad weather.
The specific reason or official explanation from the brand for changing the name has not yet been confirmed.
