The Heavy Mirage Jacket is not an illusion, but given that it weighs only 115 grams, you may forget you have it on. Constructed from polyamide ripstop, the fabric has a dry, crinkled handle and feels fantastic. Details-wise, the smooth running YKK zip goes into a protective garage at the neckline for comfort, while the low-profile hood is shaped to not impinge upon peripheral vision. A single zipped pocket for accessories also acts as the Mirage's pack sack. Rounded out with elasticated bound cuffs, plus a vented yoke to the upper back and bound vents at the underarms for breathability.
