Importance of Base Layers
There is a phrase that has long been said amongst mountain climbers, “if you wear cotton on a mountain, you won’t survive” It is true that cotton has a pleasant feel and retains heat well, qualities which make cotton great for casual wear. But when climbing a mountain, cotton’s highly absorbent properties can be harmful and when large amounts of perspiration accumulate in your clothing, being unable to dry out becomes a problem. Normally, perspiration is one defense mechanism to the body which is to cool the body through evaporation. But if your clothing cannot dry out and remains wet for an extended period, the body begins to lose unnecessary amounts of heat by conduction through the damp clothing and evaporation. Gradually the body can lapse into hypothermia and if no action is taken, eventually death.
Hiking, trekking and climbing are all activities which involve swings in body temperature. When active, the body produces heat and perspires, and when finally emerging onto a ridge blasted by cold winds, the body temperature can drop to the point of shivering. Sudden rises or falls in body temperature can result in life-threatening issues such as hypothermia. It is therefore extremely important to consider the base layer. A base layer, which also known as underwear, is the layer closest to your skin and should act as a constant 'second skin' throughout your activities. Base layers provide a layer of warmth while absorbing and evaporating your sweat to keep you feeling warm and comfortable. Each material of base layer has its own unique characteristics; quick-drying properties, moisture absorbency, elasticity and heat retention. Choosing the material is essentially choosing how you plan on maintaining your body temperature. Let Montbell introduce you the materials of Montbell base layer, Super Merino Wool and Zeo-Line.
