Whatever your alpine pursuit, be it skiing, snowshoeing, climbing, the Mont Supersonic Jacket with an athletic hip length cut, ventilation, adjustable hood and durable 3-layer Hydronaute Pro fabric, ticks all the boxes.
Alpine adventures demand waterproof, windproof and breathable outerwear that allows complete movement without restraint. Whatever your alpine pursuit, be it skiing, snowshoeing, climbing, the Mont Supersonic Jacket with an athletic hip length cut, ventilation, adjustable hood and durable 3-layer Hydronaute Pro fabric, ticks all the boxes.
Inside you will notice micro-tape factory sealed seams that are 100% waterproof while being significantly less bulky than standard seam tape. This new 14mm seam tape tests successfully at 3psi for 3minutes just as the previously used 22mm seam tape; waterproof seams with reduced weight and bulk.
Spacious enough to fit over a climbing helmet the 3-piece hood has adjustment points around the crown and face for maximum protection and comfort. Combined with Mont's signature wired-brim the Supersonic hood can be shaped and fitted for any condition.
By constructing the Supersonic Jacket with a curved zip finishing to the side of your chin we have drastically reduced abrasion caused by zipper hardware. Underneath is a laminated flap with a soft face fabric and smooth seams.

Using a combination of different layers is the best system for staying dry and keeping warm in winter, or comfortable in summer. Below is a simple guide to the different layers and garment types that can build a great layering system for a wide range of adventures.
Base layers and Next to Skin: This is your first layer and it should be a layer that wicks moisture away from the skin and drys quickly. Polartec Power Dry® garments are the perfect first layer, keeping you dry and comfortable in a wide range of conditions. We do not recommend merino as a base layer as it will absorb up to 30% of its weight in sweat, will become heavy and is very slow to dry.
Fleece & mid layers: A perfect second layer should be a warm, mid weight fleece garment or similar. Something with good stretch and moisture management is ideal.
Insulation layers: In colder conditions and for snow and alpine sports, a warm insulation layer is a great idea. Depending on conditions and how much you feel the cold, consider another fleece layer or a synthetic or down insulated garment. Garments in this category may have a hood, and also be wind & water resistant to delay the need to put on your shell jacket in cold windy conditions. When purchasing insulation layers ensure the sizing and fit allows for a base layer and lightweight mid layer underneath.
Shell Jackets: This waterproof, windproof and breathable layer is your essential piece of gear. It will keep you dry when the heavens open up, or shield you from blizzards in alpine winter conditions. Wear it over a single layer in mild weather or layer up in extreme cold, this garment should always find a place in your backpack. When choosing a shell jacket for bushwalking, trekking, ski or alpine climbing always ensure the fit and sizing allows for a base layer and some mid layers underneath, this way you can use it on adventures all year round.
Insulated Shell & Belay Jackets: If you're heading to Antarctica or have an alpine climb in mind, then it is common to have a very warm insulated outer layer. You can wear it at a high camp or over your shell jacket and other layers whilst on a frigid belay or an unexpected bivy. This is a specialist piece of gear for those who feel the cold or are heading to the high mountains. Ensure the fit allows for multiple layers to be worn underneath.
