Bamboo or wool in the winter cold
Short answer: Wool is warmer and better for very cold days and long spells outdoors, while viscose from bamboo is soft, thin and good as a layer close to the skin. Choose by the strength of the cold, activity and how sensitive your skin is.
Two materials with different strengths
Wool and viscose from bamboo are very different, and that is why the answer is not either or. Wool insulates well, because the fibres trap air, and it can hold warmth even when damp. Viscose from bamboo is soft, smooth and thin and feels cool, but does not give the same warmth on its own. Choose by how cold it is and how long you are outside.
Wool: the warm classic
Wool is a naturally insulating material that is hard to beat when the temperature drops. It suits long days outdoors, hikes in frost and cold, unheated rooms. The drawback is that wool can itch against the skin for some people and requires careful washing. If you are sensitive, choose a fine, soft quality or wear a thin layer next to the skin under the wool.
Bamboo: a soft base close to the skin
Viscose from bamboo is soft and smooth against the skin and absorbs moisture, so it works well as the layer closest to the body. It adds little bulk and can be worn under other layers without rubbing. For everyday winter in heated rooms and on short trips, bamboo is often enough. In hard cold it needs a warmer layer over it. See bamboo bodysuit for a thin layer that sits close.
The layers make the difference
The best winter solution is rarely a single material. Use a thin, soft layer next to the skin, a warm middle layer and a wind and waterproof layer outside. Here bamboo can be the base and wool the middle layer. That way you get both softness and warmth. It is also easy to take off a layer when you get warm. See bamboo trousers for women for a soft layer for everyday.
Activity and sweat
If you are active, the layer next to the skin must be able to absorb moisture, or you will get cold when you stop. Viscose from bamboo absorbs moisture but does not dry quickly, so for longer activity in frost you may need an extra layer to change into. Wool keeps its warmth even when damp. See bamboo sports bra for active days, and remember to change if you get wet.
Care and fit
Wool often needs gentle washing, and viscose from bamboo should be washed at 30 to 40 degrees without fabric softener. Always read the care label. Both can wear if rubbed a lot. The fit should be close enough to hold warmth but not so close that it restricts movement or circulation. If you have persistently cold hands or feet, talk to your doctor.
Our recommendation by situation
Choose wool for long spells outdoors, hard cold and as a middle layer. Choose bamboo for layers next to the skin, for heated rooms and if you are sensitive to wool. Combine them if you want both softness and warmth. Always choose by how long you are out and how active you are. Take an extra layer so you can adapt when the weather changes.
