This insulation is designed to provide continuous warmth. It's likely named "37.5" because it aims to maintain an ideal core body temperature of 37.5 degrees Celsius for the wearer. Provides Continuous Warmth and Good Air Conditioning: This means that the insulation in the jacket is engineered to keep you warm in cold conditions by trapping your body heat, while also allowing for effective moisture management. This prevents you from getting too hot and sweaty inside the jacket. Water-Repellent Outer Layer: The outer layer of the jacket is treated to be water-repellent. This means it can withstand light rain or moisture without getting soaked. This feature makes the jacket versatile for outdoor use. Can Be Worn Outside or as a Middle Layer: Because of its water-repellent feature and insulation, this jacket can be worn as an outer layer in mild weather conditions. In colder or wetter conditions, it can serve as a middle layer under a waterproof shell jacket for added protection. Long Arm Cuffs with Thumb Grip: The jacket has long cuffs on the sleeves. These cuffs can be extended to cover your hands and include thumb grips. This design provides extra warmth and comfort, as well as keeps the sleeves in place. High Collar for Additional Wind Protection: The jacket has a high collar, which means it covers more of your neck and chin area. This is useful for protecting you from the wind, especially in cold or windy conditions.
