Comfort is everything!

Comfort is a very vague word. By definition it means comfort is the absence of discomfort. A functional garment can help you to stay comfortable even in changing outdoor environments by providing the right level of comfort and protection, thereby preventing you from overheating or cooling down.

Your microclimate

Our feet perspire a lot considering their size in comparison to the rest of our body - roughly one quarter of a cup of moisture a day per foot while at rest and up to one full cup during activity and/or in hot weather. So you need your shoes to be able to keep your feet comfortable, whether you are at rest all day or active and in motion.
Our legs make up about 30% of our entire body. That’s too much surface to ignore when you’re trying stay comfortable. We use the same pair of trousers for out on the ski slopes and in the hot ski lodge, so make sure the pair you choose can deal with all the different environments during your day.
Our torso is like one big land mass. Cold and wet in one spot, warm and dry in another. Your shoulder and lower-back regions are particularly sensitive to excessive cooling and require extra protection from the wind and cold. If you want to stay comfortable, your clothing should take these "zones" into account.
When it comes to your arms, freedom of movement is more important than warmth. Your arms can actually be up to 45ºF/ 7ºC colder than your torso – without you even noticing it. But ever try skiing or golfing in clothes that don’t allow your arms a full range of motion? Forget it.
Our hands have it rough. They perspire a lot, they’re exposed to all sorts of extreme conditions and they have to endure reduced blood circulation in cold weather. No wonder they are so prone to freezing. How your hands feel, the rest of you will feel. So keep your hands warm and dry at all times.
Sometimes you can forget how little fat or tissue there is between the warmth of your brain and the cold environment, and when you leave your head unprotected you can lose more heat just from there than your entire body can produce. That's why wearing a hat can be essential in cold conditions.

The thin layer of air that surrounds your body, known as your microclimate, is essentially what keeps you comfortable. The ideal microclimate is around 90°F/32°C and humidity of less than 30% - this is the temperature that we, as humans, are most comfortable at. But what's good for your hands isn't always good for your shoulders. Or your legs, for that matter. In cold weather, our arms and legs can be up to 45°F/7ºC colder than the rest of our body - without any perceived discomfort.

Climate control

Moisture Management

You can't control the conditions you're in but you can control the microclimate around our body. The clothing you choose controls heat transfer, moisture, and protects us from the weather. This is how our clothing keeps us comfortable.

Heat balance

To be comfortable the amount of heat your body produces must balance with the amount of heat it loses. Get too hot and you’ll sweat. Get too cold and you’ll start to shiver to ward off hypothermia. The best way to stay comfortable is by wearing clothing that offers total windproofness and maximum breathability. The wind won’t reach your skin to cool you down and perspiration will easily escape instead of sticking to your skin, leaving you all wet. For more intense activities and heat, wearing garments fitted with ventilation zips will allow you to easily release extra body heat as needed.

Weather protection

Your clothing must protect you from the elements. If it can't do that, then it can't keep you comfortable. Wind, cold, snow, rain… outdoor gear must create a protective barrier between you and whatever forces of nature have been unleashed upon you. The best defense is a clothing system made up of functional layers that work together to ensure an optimal combination of windproofness, breathability and water protection so that you stay dry and warm.

Clothing systems

High muscle mass plus constant movement equals lots of opportunity for creating heat. Just like the rest of your body, your legs need to stay comfortably warm and dry if you want to perform at your best. But since you can’t always dress your legs according to the layering system, you need trousers that offer effective wicking, insulating and weather protection abilities - all in a single fabric. Equally important, trousers must allow your legs total freedom of movement.
Gloves have a very complex role to fill as they must be completely windproof, waterproof and offer maximum breathablilty to keep hands warm and dry. They also need to be made of durable fabrics tough enough to withstand wear and tear - and include extra layers of protection on the palm and finger areas to resist abrasion and provide a sure grip. Equally important, they must not interfere with dexterity.
A good hat has to keep your head warm and dry. How? By slamming the door on windchill, keeping the weather at bay, and letting perspiration escape.

If you want to be able to bare the most extreme weather conditions and intensive activities, you need to wear the right equipment. 
When running 15 kilometers under the hot sun, or carving up the slopes in biting winds, you have to select the right clothing systems.
