How to stay warm
Warmer hands layer by layer

You can keep your hands dry and warm by combining gloves with different features. This is how you can layer and vary your gloves to adjust to changing temperatures and your activity levels.
Hestra glove system
The Hestra glove system is based on the layering principle - the idea of wearing many different functional pieces of clothing. By using layers of gloves, you can regulate the temperature according to the weather conditions and your activity level.
Inner layer
Liner
Closest to your skin, wear a liner that carries away moisture and creates a thin, warming layer. You should keep it on to avoid contact with cold surfaces when performing tasks that require finger dexterity.
A thin liner worn inside a glove increases heat by about 20 percent.
Second layer
Base glove
The base glove is the one you use most frequently. It keeps your hands warm in normal cold conditions, wicks away the moisture and provides protection against windy and wet weather conditions. The base glove is available with a fixed or removable liner. A removable liner makes it easier to regulate the temperature.
Outer Layer
Shell Gloves
Shell gloves are a layer of added protection that you pull on when it's biting cold, wet or if you're standing still for prolonged periods. This creates another layer of air that insulates against the cold. Adding a liner and shell glove increases heat by approximately 50 percent compared to only wearing a base glove.
A shell glove doesn't take up much space and can easily be rolled up for easy storage and access.
Combination based on your needs
There are many combinations – select models based on your needs and the activities and weather conditions you expect to encounter.
Use thin liners when better dexterity is needed. During activity your body temperature rises, but the wind can still chill your hands. Use a windproof base glove that is highly breathable. Remember, gloves with waterproof inserts like GORE-TEX and CZone may limit the ventilation. When you stop to rest you need more insulation then when you are moving - add a shell glove on top of your base glove.
Heart before hands
Hands and feet are the first body parts to suffer when you are out in the cold. They are furthest from the vitals in the core of your body - your heart, brain spinal cord and gastrointestinal tract. The fine mesh of capillaries in the fingers and toes is shut off when it gets too cold and the tips of your fingers turn white. You could say that the body "sacrifices" less important parts in an attempt to save the organs that are essential for survival.
The point is that your hands and feet need extra protection when it's cold to compensate for the body's natural function. Remember that even if your body is warm in general, your hands can still get frostbite.
