I purchased this at a THE NORTH FACE directly-managed store and have kept it as part of my collection, so I've only worn it to try it on at home. The condition is almost new, so if you're looking for one, please consider it. It is definitely authentic, and I will also include an authenticity check. Brand: THE NORTH FACE Product Name: Trans Antarctica Parka Color: Black Size: M (It has a large fit.) Retail Price: ¥79,200 Shoulder Width/Body Width/Sleeve Length/Length Shoulder Width: 58cm Body Width: 58cm Sleeve Length: 78cm Length: 82cm ■Material ＜Outer Fabric＞200D Recycled Nylon Tussah GORE-TEX (2 layers) (Outer: 100% nylon, Inner: ePTFE) ＜Lining＞TNF Embossed Taffeta (100% polyester) GORE-TEX PRODUCTS 【Ventilation】 In conjunction with the PAC system (Physical Active Construction), ventilation is placed in a position that does not hinder movement and can be operated without stress during activity, and is equipped on all models. Even when using GORE-TEX, it is difficult to sufficiently control the steam caused by perspiration during hard hikes or when the outside temperature is high and the difference in water vapor pressure inside the clothing is small. Ventilation is essential to maintain a constant environment inside the clothing and prevent a drop in body temperature and the accompanying decrease in physical strength by actively releasing steam. In 1989, an international team composed of members from six countries, including Japanese adventurer Keizo Funatsu, challenged a trans-Antarctic crossing to appeal for the importance of the environment and peace, and in March 1990, all members successfully reached the goal. This is a hooded waterproof shell jacket designed based on the wear worn by the members of the Antarctic crossing team at the time. It uses a GORE-TEX PRODUCTS 2-layer structure and a durable 200-denier recycled nylon outer fabric. The front has a double-flap design to improve waterproofness. Ventilation is provided under the arms to efficiently release stuffiness inside the clothing. The flags of the countries that participated in the trans-Antarctic crossing are placed on the left chest and back, and a "TransAntarctica Expedition" silicone patch is placed on the left arm. It has a long length that covers the hips.
