Protection

Flexible or rigid protective garments, also called shells, protect you from the elements like wind, rain, and snow. They are lightweight, breathable, and tear resistant for long-lasting protection.

Lamination

The process of applying a protective membrane to the main fabric of a garment.

Windproof, waterproof and breathable pictograms

Two-Layer Membrane

The membrane is glued to the outer layer rather than the lining, protecting the membrane from wear.

Three-Layer Membrane

The outer layer, the membrane, and the lining are joined to form a single fabric. The three layers make the garment even stronger.

The garment repels water. Heavier rain will eventually get through. Water repellency fades over time, but can be maintained with the proper products.

The type of fabric or finish used on the garment completely prevents water from passing through.

This is measured in millimeters. If the water resistance level is less than 8,000 mm, the garment is water repellent. Anything above 8,000 mm is considered waterproof.

Breathability Index

Breathability is measured in grams per square metre and refers to a fabric's ability to wick away water vapour and moisture such as perspiration. A fabric with good breathability will considerably reduce the amount of moisture that accumulates in the garment. Wet skin cools down more quickly, so it's important to choose activewear with good breathability to prevent you from getting too cold or overheating.

Warmth

Figuring out the perfect combination of clothes to wear is the key to staying comfortable when practicing cold weather sports. What base layer do you choose? Which insulation? What weight? Your needs will change from fall to winter, skiing to running, morning to night.

Thermoregulation: Merino and Synthetic Knits

Merino Wool

This naturally technical fibre neutralizes odours and prevents bacteria from growing. Athletes love how soft and delicate it feels against their skin. It makes excellent outerwear because it keeps the wearer warm and wicks away moisture.

Polar Fleece and Synthetic Knits

In addition to being extremely comfortable, these fabrics dry very quickly. They are also generally affordably priced. The underwear, in-between layers, and fleece jackets come in various thicknesses, and can have antibacterial treatments applied to them to reduce odours.

Take a look at the weight listed on your merino undergarment.
It will likely be between 100 and 300 g/m².

The more it weighs, the denser and warmer the garment will be.
