Chest: Take measurement around the fullest part of the chest, just under your arms and across the shoulder blades.
Sleeve: With arm relaxed at your side and slightly bent, measure from centre back of neck, across shoulder, to your elbow and down to your wrist.
Waist: Measure around the smallest part of your waist (natural waistline).
Hip: Standing with feet hip width apart, measure around the widest part of the hips.
Next to Skin Fit: Designed to be worn next to skin. Body hugging fit for thermal and moisture management.
Active Fit: Trim fitting garments, ideal for active pursuits. Designed to fit over a base layer as required.
Regular Fit: A classic comfortable cut. Designed to fit over base and mid layers without restricting movement.
Relaxed Fit: A generous and relaxed fit. Cut loose enough for layering.
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.

The Helios Jacket is the result of years of design refinement with precision in every detail. Developed to meet the needs of alpine climbing, technical mountaineering and remote alpine camps, the Helios is engineered for high-altitude environments where warmth, protection and mobility are critical.
900+ loft RDS white goose down in a box-walled construction forms the thermal foundation, utilising our PFAS-free Hydronaute XT Mont’s most breathable and weather-resistant shell fabric. The interior features a recycled nylon ripstop lining treated with XReflex™ radiant barrier technology, which reflects body heat to improve thermal retention.
The 4-piece helmet-compatible hood has been shaped through extensive prototyping to maintain vision and mobility while wearing a helmet, even in exposed conditions.
The Helios keeps you warm through bitter wind chills, is tough enough for belays on wind-blasted ridgelines and refined for summit pushes high on technical terrain.
It is the most advanced technical insulated jacket Mont has ever created.
All Mont Down Sleeping Bags come filled with premium down with a water resistant treatment called DWR Loft.
DWR Loft protects down from moisture and maintains loft in wet conditions Retains loft and warmth, greatly reduces drying time, extends the life of down garments or sleeping bags & improves resistance to bacteria growth.
We are committed to removing all fluorocarbons (PFAS) from our Mont products. The construction of our shell wear membrane technology, Hydronaute, has never contained PFCs and our DWR coating that is applied to this shell wear is PFAS-free*.
This is just one of the many steps we have taken to care for our people and the planet.
*non-intentional PFAS
This product is filled with Premium White Down with a loft rating of at least 900 cubic inches per ounce.
Mont's down is selected for it's high quality, purity and the fact that it is not live plucked.
RDS is an independent, voluntary global standard that ensures down is not sourced via live plucking, that birds are not force fed & that a birds welfare is always upheld.

XReflex® mitigates the body’s natural heat loss by utilising our patented deposition process to apply ultra-thin, breathable radiant barrier surface coatings onto fabrics.
These radiant barrier surfaces reflect body heat, increasing heat retention to create thinner, lighter and warmer products.
Comfort in the Extreme: Using advanced monolithic PU membrane technology, Hydronaute XT fabric is completely waterproof, totally windproof & highly breathable. Guaranteed to maintain greater warmth & comfort than coated fabrics, Hydronaute XT is the best protection for down sleeping bags & clothing in cold to extreme conditions.
Keeping down dry is vital for optimal performance; wet down just won't keep you warm. Waterproof Hydronaute XT fabric provides exceptional moisture protection for down clothing & sleeping bags.
Highly Breathable: If not removed promptly, water vapour from your body will gather on down & reduce its ability to trap warmth.
Warmth Sealed In: With a 100% windproof rating, even Arctic blasts will not penetrate Hydronaute XT fabric, keeping warm air trapped inside.
Box Wall Baffles are the warmest type of baffle for down sleeping bags.
Box Wall Baffles are three dimensional chambers that create maximum loft of down and uniform distribution throughout the sleeping bag.
Box Wall Baffles are in contrast to sewn through baffles, where the outer fabric is sewn directly to the inner fabric. Sewn through baffles are lighter and more compact but provide significantly less insulation.
