Layers in clothing help keep you dry, which is crucial to staying warm. Cold and humidity put you at a higher risk of hypothermia, which can be life-threatening. And if you suffer from hyperhidrosis, layering is essential for comfort and safety in cold weather.
1.A Base Layer
Often referred to as the next-to-skin layer, the base layer is arguably the most important layer, as its purpose is to move moisture (like sweat) away from your body. If your sweat isn't being sucked away, you'll be getting colder.
For your base layer material, generally, you'll see one of two materials: natural fibers like wool and bamboo or synthetics like nylon and polyester. You can choose one of them. We prefer merino wool. It is lightweight, breathable and odorless, making it an ideal material for moisture management.
You want to make sure it fits snugly and comfortably. Try to avoid cotton material as it is actually hygroscopic and can leave you cold. We prefer to use natural fibers rather than synthetic fibers like polyester. They all work equally well, but we found that Merino worked a bit better.
2.A Mid-layer
The mid-layer is the second component of the mezzanine, located between the base layer and the shell, aptly named. The role of the middle layer is to retain heat. It does this by capturing all the body heat you lose while exercising outdoors. Therefore, the more efficient your mid-layer is, the warmer you will be. Most people think that you need to wear a huge parka to keep warm. But the key is actually layering for breathability.
Due to the material, the middle layer is usually fluffier or larger than the base layer. There are a variety of options, but most mid-layers are constructed of wool, fleece, down insulation, or synthetic insulation.
For mid-layer, we suggest wool or fleece. Wool insulates best, so that's what we like too. Although when it gets wet, it doesn't perform that well. You can pack heavier weights for very cold days, or lighter weights for days hovering around freezing.
3.A Outer Layer
The outer layer (or shell) is the third and final component of a layered three-piece, the garment that sits on top of the other two layers. The purpose of the outer shell is singular: to keep out wind, rain, and snow, and to keep your inner layers dry. Unfortunately, many people skip the first or second layer and jump straight to the outer layer, which is not the best defense against biting weather.
When choosing an outer layer, keep in mind that it will cover the other two layers. So make sure it's big enough to cover other clothes without being too tight.
