Lightweight insulation for demanding hiking trips. The Zeno track delivers warmth without weight. This is because the fill in this hybrid jacket is predominantly high-grade duck down with good lofting capability. For the shoulders, sleeves and hood we have opted for a less sensitive and more robust fiber cloud synthetic fill. It retains its insulation performance even when damp or when pressure is exerted on it. The Storm lock outer fabric also gives you good protection from the wind. The Zeno track is equipped with a system zip, so you can simply zip it into a compatible weatherproof shell jacket as a very warm liner. The jacket stows neatly inside its own hip pocket. Because it is made from lightweight materials, the Zeno takes up very little space in your pack, which makes it a practical insulation solution for all situations.
