The N-3B is a cold-weather parka that is designed to be used both for flying extremely cold transport aircraft and for outdoor work on base. The fur on the hood, which can be worn while wearing a large helmet, blocks out snow. A large wind flap is there to block wind from penetrating through the front zipper, and large buttons are used to allow fastening even while wearing gloves. There is no shortage of details designed for warmth, such as built-in ribbing on the cuffs and a waist cord that can be tightened for extra warmth. The functional beauty of flight jackets transcended the category of military equipment and began to spill over into civilian clothing before one becomes aware of. The shell of this N-3B is made of polyester blended cotton woven fabric, which has the characteristic of expanding when the cotton absorbs moisture, filling the gaps in the fabric and preventing rain and moisture from entering. It is also more breathable than cotton fabric and more resistant to abrasion than polyester fabric. When developing new flight jackets, the most advanced materials of the era have been adopted. And by using even more advanced materials, flight jackets gain even newer functionality.
