100% nylon. 95% down, 5% feather insulation. Full press stud fastening. Chest pocket. Press- stud adjustable cuffs. Curved hem. Packable. Regular fit. Taion’s Basic Down Shirt is indeed a stripped-back shirt that’s been stuffed to the gizzards with exceptionally toasty down. Thanks to that low-profile design, this is down garb that doesn’t have to be worn when squaring up with elements up some perilous peak – it’s equally as apt for civilian sojourns too.
