Thank you for viewing. It boasts exceptional warmth as an inner down layer. This item is in very good condition. I think it will be useful for winter camping, etc. DESCENTE ALLTERRAIN DESCENTE ALLTERRAIN H.C.S. DOWN PULLOVER SHIRT Down Pullover Shirt DIA3476 (JP) Navy [Model Number] DIA3476 [Size] L (JP) [Color] Navy [Material] Outer fabric: Nylon: 100% Lining: Polyester Filling: Main body down: 90% Feather: 10% Underarms/Sleeves: Polyester: 100% Inspired by the structure of a sleeping bag, this lightweight and thin down shirt was developed to pursue heat retention and wearing comfort, and is extremely heat-retaining. HEAT NAVI, a heat-generating and heat-retaining material developed by Descente, is used for the lining. The side parazip allows the side of the shirt to be easily opened with one hand, making it very easy to put on and take off, despite being a pullover shirt.
