Your Guide to Coats & Thermal Layers

Being active in the winter can be intimidating unless you know your gear. What kind of clothing is warmest? Which fabrics are the most breathable? What material should you choose for a specific activity?

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.

Water Repellent, Waterproof, and Water Resistant

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

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

Water resistance index: 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.

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.

How to Care for a Down and Feather Coat?

Wash your garment at home if you can. Professional cleaning products are too strong and pungent.

Wash your coat separately in cold water, by hand or on the gentle cycle.

Only use mild liquid soap.
Do not use fabric softeners, bleach, or products with chlorine in them.

Rinse your garment at least two or three times. Doing so should remove any soap residue. It will also make the down and feathers fluffier.

Dry your garment in the dryer on a low temperature. Add a few tennis balls to the dryer to speed up the process and give the coat more volume. Do not air dry your garment: it takes a lot longer to dry, which could give mould time to develop.
