I absolutely love the short-sleeve design of this jacket (warmer than a vest, lighter than full sleeves), unfortunately I've outgrown mine due to having bought right after a long hike.
Original Japanese unisex sizing from U.S. debut in '07 is XL, or U.S. Large per the label. However the fit is actually more of a Men's medium, 38-40" chest.
This jacket has been well cared for and has never been worn with a pack. Loft remains like new. Laundered just once, prior to sale, with detergent for down.
Includes jacket (6.8 oz) and original stuff sack (0.2 oz).
$65 with CONUS shipping included. PayPal preferred.
