Merino wool next to skin base layer
In the old days we called this layer "underwear", however, modern technology dictates a more scientific sounding title for the most essential layer to help regulate your body temperature.
A base layer is in direct contact with your skin, its primary role is to transport moisture away from your body and into the mid/outer layers for evaporation. Merino wool is an excellent material for a base layer, by absorbing moisture and retaining it in natural hollow fibres providing insulation against heat loss. This explains why merino wool keeps you warm even when it is wet.
Other materials like cotton and synthetics do not possess the ability to absorb moisture. Dampness sits on the surface and the wet garments will draw heat from your body causing rapid heat loss and a drop in your core body temperature making you feel cold and uncomfortable.
Merino wool creates a personal micro climate around your body keeping you warm when the ambient temperature is cool and cooling you down when the temperature is warm.
Merino' wool has a high warmth to weight ratio means you can wear a lightweight base layer even in the coldest conditions as long as you add suitable mid and third layers.
Our snug fitting Thermerino Base Layer performs in all conditions and are available in either navy or black.
Merino wool mid layer
A middle layer provides additional insulation and continues to transport moisture away from the base layer.
The addition of another merino wool layer increases insulation adding pockets of air space between the two layers. The middle layer once again absorbs moisture and performs the same as the base layer when regulating your body temperature.
The middle layer should still be a snug fit like the base layer but not so that it constricts body movement during manoeuvres. We designed our garment a longer arm and body so that it does not ride up during extreme stretching exposing skin to the elements.
Our Light Weight Zip includes a quarter zip that allows the collar to envelope your neck preventing heat loss. The zip can be opened to provide increased ventilation during rigorous activity.
Merino wool mid layer as a third layer
In extreme conditions you will need to add a third layer to provide maximum insulation and warmth. A looser fit than the other layers will compliment heat retention by contributing addition air space that will trap warm air.
Like the middle layer our Heavy Weight Zip has a quarter zip, a longer body and longer arms. Using a heavier merino wool knit makes it suitable for very low temperatures. Its ability to breathe regulates your core temperature and prevents you from getting too hot under exertion.
Finally, we recommend using a Gore-tex outer layer to protect you from wind, rain or snow and allow moisture to evaporate into the atmosphere.
