Features To Consider Before Buying
We will now discuss the four types of base layers, the various weights of them, and will help you learn how to choose the right base layers for the weather you have, among other factors to consider.
Types Of Base Layers
Synthetic: The majority if base layers are synthetic or wool, which also include polyester and other material to help keep your base layer flexible and warm. However, synthetic base layers do not breathe well and are not quite as warm as other material. Plus, it will hold in odors more than others.
Merino Wool: This is good for cool or cold weather and allows you to exercise easily and stay warm. Even on warmer days, this material is great to wear. Base layers made from wool with fleece keeps skin protected from the cold conditions as well as the sun.
Silk: This is a great material for colder climates and for those who enjoy winter activities and exercises that do not involve a lot of movement. Silk base layers wick away sweat and moisture and keeps it away from the skin. Silk can get smelly, so wash it after each time you wear it, and it cannot protect your skin from sun damage.
Bamboo: Using bamboo as a base layer is a fairly new idea, but when it is joined with cotton, fleece or even Lycra, it can be just as good as a wool base layer, and it will keep its shape over time. Using a bamboo base layer is better for people who dislike the feeling of wool.
Weights Of Base Layers
Light weight: When choosing a light weight base layer, know that these are more for higher impact workouts and activities in warmer temperatures. They are generally cheaper in price and easier to put in your backpack than something bulkier.
Mid weight: This the most used type of weight for base layers and are generally used in the autumn or spring times. This is just a little bulkier than a light weight and just less bulky than an expedition weight base layer and it weighs twice as much as a lightweight base layer.
Expedition Weight: This type of base layer is the thickest and is used in cold and frigid weather and for more difficult activities in the winter. This type of the protective layer is way higher in price, but can keep you warmer than other types of base layers.
Warmth is the most important factor when choosing a base layer. Your base layer should provide warmth, but not allow you to sweat too much. You need to find balance. Use a less warm base layer if you are going to do a lot of exercise or if you find yourself in warmer temperatures.
While keeping warm is a must, your base layer should breathe, so that you do not build up a sweat.
Your base layer should allow some water vapor to pass through it, which means it will go back into the air and your body will not be too affected by it.
Nobody wants to be wet when they are outdoors, especially in cold weather. Your base layer will no doubt get wet at some point and knowing the time it will take to dry can help you in purchasing a new base layer. Do not forget, a wet base layer can make you feel really uncomfortable.
Because some base layers can be quite pricey, you will want to make sure the product you are purchasing will be durable, which means it will last a long time.
Synthetic base layers will be very durable, whereas a wool base layer may not last as long.
Being comfortable and having the right fit of a base layer will ensure you have a great time outdoors. If it retains static, you can get shocked. Try on your base layer if possible, before you purchase it, so you can make sure it not only fits right, but will be comfortable when you are enjoying outdoor activities.
