In Australia, we are lucky to have such a sensational spread of winter sports - skiing, climbing, snowshoeing... just to name a few.

If winter sports are right up your alley, you're going to need a top-notch merino vest. The Helix Vest has been designed to deliver remarkable insulation in cold, alpine climates during high-output, fast-paced activities.

The vest combines sustainable materials with a technical design - for maximum performance in frigid temperatures. In the body, you will find Icebreaker's MerinoLOFT insulation which offers a warm, breathable & natural alternative to other synthetic insulations.

The polyester face fabric is 100% recycled and it has been treated with a DWR (durable water repellent) finish that helps fend off light precipitation. The side panels are built from a stretchy merino jersey that will help regulate your body temperature on active days, whilst the 100% woven merino lining ensures that you are cosy from the inside. You can stash your small essentials (money, phone & snacks - the important things, right?) in the zippered hand & chest pockets.

  • A 100% polyester face fabric houses the unique MerinoLOFT™ insulation.
  • The exterior is treated with a DWR (durable water repellent) finish for moisture-resistance.
  • Ideal for winter sports, hiking & travel.
  • Regular fit.
