The brain is one of the most metabolically active parts of our bodies, generating and losing heat continually, it is important that it is kept at normal body temperature for correct function. The head acts like a radiator that can't be turned down.

Features to look for in a hat for extreme cold conditions

---

Wearing a hat is one of the quickest and easiest ways of keeping warm with the advantage that hats are relatively cheap and light to carry. However you are dressed putting on a hat is a simple and very effective way of warming up.

We don't really feel the cold in our head like the rest of our body (when was the last time you had a cold head?) so it doesn't always seem a particularly obvious thing to do. Getting into the habit of putting on a hat when you stop for a break and so stop generating heat by movement is a good one to develop for your comfort and safety.

A variety of materials are available, my personal preferences are:

1- A synthetic fleece wind stopper hat - small enough to take up very little room in a pocket with a warmth far beyond what should be reasonable for its size and weight, the flaps can be pulled down when it gets colder or folded up when not so cold. It has a layer to stop the wind in its tracks and the clean smooth shape means that a hood fits neatly over the top with no chilly gaps.

2 - A shearling trapper or aviator style hat this is bulkier than my other choices and it's for those times when you know it's really cold and you're going to have it on the whole time. Genuine shearling is far more effective than faux, there is no comparison in softness, comfort and warmth. Again a clean shape makes a hood fit neatly over the top, I look forwards to wearing mine when winter gets cold enough..

3 - A balaclava can be worn rolled up as a hat or rolled down as an almost full face covering under your hood. If they cover the mouth and nose, they have the advantage of keeping that area warm, so decreasing the chances of picking up colds and flu which can get a better foot-hold in a chilled upper respiratory tract. You'll need another hat or hood too when it gets really cold, but they aren't so expensive.

In extremely cold weather you will have a shell-garment with an attached and probably insulated hood. Hoods limit visibility and awareness of the world around you and can be quite noisy as they move against your ears. A hat allows you to keep warm with greater freedom of movement without the hood being raised they provide extra insulation when you do raise the hood in response to increasing wind speed and dropping temperatures.

There are an almost endless variety of hats available, all of which will help to keep you warm to some degree. The most effective are close fitting, cover the ears and preferably are without external additions such as pom-poms that prevent a close fit when a hood is pulled over them.

Materials - polyester fleece or natural materials such as wool (merino wool is premium), shearling (sheepskin) or fur are very effective and should be chosen for maximum performance.

Thinsulate - a brand name of synthetic insulation that is often found in hats and gloves. Thinsulate is effective and usually fairly inexpensive, preferable to acrylic for a similar price though less hard wearing.

Cheaper hats are often made from acrylic which provides less warmth than those materials already listed and are more bulky when stored in a pocket or backpack. This might however be an advantage if you are wearing the hat for fashion purposes as you can still wear it even though it is not so cold without over heating.
