Are you going to move around a lot with a good chance of getting too warm and sweaty, or will you be standing still for a long time risking to be really cold during the time? A good way to stay warm and dry is to follow the layering principle. Even if you don’t wear all layers it’s a good idea to take base, mid and outer layers with you on all adventures.
Base layer – wicks sweat off your skin (moving perspiration), keep your skin dry.
Mid layer – (insulating layer), retains body heat to protect you from cold, In general thicker equals warmer though the efficiency of the insulating material is also important. transport moisture.
Outer layer– shields you from wind & rain, release moisture. Often lumped into waterproof/breathable shells, water-resistant/breathable shells and waterproof/non breathable shells.
Reinforcement – insulating layer. Hat, mittens, shoes.
In addition to the layers you also want to consider the type of fabrics you are wearing. A garment with a weave of wicking or wicking treatment may do wonders pulling perspiration off your skin while still keeping warm.
Wool – odorless, itchy for some, keeps you warm even if wet, best warmth, wicks away moisture, don’t need to be washed so often.
Cotton – binds a lot of water, conducts heat away from the body, heavy, dries slowly.
Synthetic – dries the fastest, warms well in relation to weight, begins to smell quickly.
Down – retains heat best in relation to weight, airs well, compressible, moisture-sensitive fillpower.
- Whole, clean and well-kept clothes work best.
- Drying clothes in front of the fire can be a good alternative. Wear your pants, mittens or shoes as you dry them by the fire. If it gets too hot for you, then it is too hot for the material as well. When you wear the garment you also dry them from the inside at the same time. Socks on your hands in front of the fire or on a warm Nalgene bottle in the sleeping bag during the night is also a good alternative.
- Flat knitted wool is less airy and have more contact to the body and therefore leads better while circular knitted or terry-knitted wool traps more air and is really warm in comparison. There is also woolnet, doublewool and so on for different activities and weather.
- You want the base layer to be snug so that comes in contact with your skin so it can wick moisture, but it should never be uncomfortable or restrictive.
- Your middle layer and outer layer can really fit however you prefer, but most people want them to be neither loose nor tight. One way to think about it is that a proper fitting middle layer or outer layer should almost be unnoticeable. It shouldn’t get in your way or be too tight that it restricts movements.
- There is a difference between theoretical knowledge and practical knowledge. Use your clothes, get to know them, what do you need, when do you need it and why? Do lists before going out. Take notes during. Follow-up afterwards.
- When you try out new clothes make it as real as possible.
- Try the hood. Does it follow you as you turn your head in different directions? There are often zippers in the armpits to extract excess heat. They are available in different lengths and angles, do these ones fits you? Does the fabric go down over your back? Are the arms of the jacket long enough if you crouch down and pretend to put down the tent pegs, are the jacket sleeves long enough if you lean forward from the hip and pretend to hold a bicycle handlebar? Things like that can make all the difference later!
- Stretch in your trousers could be nice. While walking you sometimes lift you knees up high to get up on things. Stretch makes it so much easier. Try a pair of pants with stretch and put your cellphone and wallet in the pockets. Get up on a pallet or chair (90 degrees in your knee). Then try a pair without stretch. Difference? Does it matter? When windy, areas with stretch gets much colder buts it’s really nice while walking. Some trousers have zippers along the thighs so you can vent out excess heat. Would it be nice for you?
- There are many different hard shell jackets on the market. To keep it simple a shell jacket can be made of 2, 2.5 or 3 layers, and they all have the same intention — keeping you protected from the elements. A 3 layer jacket has higher water column and is more durable compared to a 2 layer jacket. Sometimes a 2-layer piece will include a third moisture-wicking layer, but it is not bonded and hangs loose within the garment. This “2.5” layer protects the membrane as body oils and moisture can contaminate it and degrade performance. For most people a 2 layer jacket is a good balance in being a
- Softshell fabric is different in that it is often more stretchy and breathable but not water or windproof. The flip side of breathability though is that winds blow right through and can steal warmth.
- DWR. Durable water-repellent is a chemical application to the face fabric of any outerwear piece. DWR enables water to bead on your jacket and roll off. It can be reactivated or reapplied when you’ll see dark spots on your jacket where water is soaking in.
If you are into wearing heavy backpacks then the 3 layer variant is sturdier, but in some 3 layer jackets you could sound “crunchy” as you move around because of the fabric. Especially in older models.
