Thermal underwear does provide some insulation but its main role is minimising evaporative cooling by ‘wicking‘ or drawing sweat away from your skin.
An example of evaporative cooling would be as follows: –
Blow on the back of your hand and imagine how that feels. Now wet the back of your hand and blow on it again, and you will notice that when your hand is wet it feels much cooler. This is because as the water starts to evaporate it draws heat energy away from your skin.
This is the same principle when you wear thermal underwear against your skin.
What are the best materials for thermal underwear
Wool is a natural fibre that has excellent insulation properties which is ideal to use for any type of thermal garment.
It can absorb more than 30 per cent of its weight in water before it starts to feel wet. This is great if you are exercising or are prone to sweating.
Has the ability to ‘wick’ moisture away from your skin.
Great for regulating your temperature whether in cold or hot conditions.
Wool has an anti-bacterial effect due to the structure of the wool fibres.
Although there is sheep’s wool and Angorra wool available, one of the most popular types of wool used for thermal garments is Merino wool.
Merino Wool is produced from the white fleeced Merino Sheep, which is dominant in New Zealand and Australia.
However, in the UK there are over 60 different breeds of merino sheep, as well as over 40 in the United States.
Due to its performance, availability and cost merino wool is now one of the most popular materials to use for thermal underwear.
Extremely soft and comfortable with a feel like cashmere products.
Merino wool has a lot more fibres in the fabric which traps more small pockets of air and locks in your body heat.
It is a highly breathable material that wicks’ moisture away from your body.
Great for regulating your temperature whether on cold or hot environments.
Protein molecules (the keratin) in the merino wool fibres are able to break down bacteria forming odours, so you won’t have to wash your thermal underwear as often.
Because merino resists stains, odours and bacteria, you don’t need to wash it as often as synthetic fabrics.
Owing to the fine fibres in the wool it is incredibly elastic, and able to retain its shape even after years of stretch, wear and repeated washing.
Merino wool has a natural UV protection.
The wool fibres are non-abrasive and suitable for people with sensitive skin.
Polyester is one of the most common synthetic fabrics available for thermal underwear. Polyester, nylon, Lycra and spandex are often combined with natural fabrics such as wool to provide the right heat retention and moisture wicking properties.
In addition you may see rayon or polypropylene as well.
Synthetic underwear is very durable and can be washed often whilst still retaining its look.
Great for dissipating and wicking away sweat from your body keeping you really dry.
Lightweight and flexible material that fits well to your body.
Synthetic fabrics are generally the cheapest of all base layer garments.
As synthetic fabrics are not naturally antibacterial they will retain the odour from sweat, so you will have to wash your underwear more frequently.
Also, synthetic thermal garments are not as warm as merino wool fabrics, so they won’t be as effective in colder conditions.
How often should you wash thermal underwear ?
Thermal underwear is classed as a ‘base layer’ which is really any layer of clothing that we wear against our skin and hair. For example, compression socks, boxer shorts, undergarments or leggings.
They all absorb body oils and sweat from our body which in turn causes odours to occur.
If you are fairly active then you really need to wash thermal underwear after every wear. If, on the other hand you are just trying to keep warm and not really moving or exercising, then you could get away with wearing 2-3 times before you wash.
However, if your underwear is washed regularly and correctly will feel fresher and last longer.
5 Tips to buying Thermal Underwear for Men
How to choose the right fabric and material when buying thermal underwear
1) Choosing the right weight for your base layer
The weight of a base layer determines the warmth that it produces. The heavier your thermal underwear is, the warmer it usual is.
It’s worth noting that heavier base layer underwear will obviously give you more warmth, but the main job is managing your moisture. It’s your middle layer that will act as an insulator retaining your body heat.
Generally there are three basic weight options for thermal underwear –
LightweightPreferable for cool to moderately cold weather and for a high level of aerobic activity. Ideally, the underwear should be close and a comfortable fit on your skin.
MiddlewightThis is best for moderately cold to cold weather, and tends to be a popular choice for thermal underwear.
HeavyweightSuitable for extreme cold temperatures and when more warmth is needed to regulate the body temperature.
Should thermal underwear be tight or loose ?
To ensure that your base layer is most effective your thermal underwear needs to have a snug fit to your skin, so it feels like you are wearing a second skin.
If there are gaps between the fabric and your skin then this will allow cold air to get in.
It’s best to always go for your actual size when choosing your underwear as they are made a slightly smaller fit than regular garments you buy.
The Best ways to wash thermal underwear
Thermal underwear is made of different types of fabric, so if you want to get the best out of it ensuring that it lasts a long time, then it’s important to read the manufacturer label when washing and caring for your underwear.
Here’s a guide to the different materials available in your thermal underwear.
Most people consider woollen items to be difficult to wash and keep clean, but most woollen thermals can be washed using a washing machine.
Ideally use a delicate cycle when you are washing followed by a short spin cycle.
Use a line drying method, not the tumble dryer to ensure that the clothing doesn’t shrink. However, certain wool garments can safely be dried in a tumble dryer without the item shrinking. Check your garments sew in label to make sure first before drying.
When looking at woollen thermal underwear, merino wool is a popular choice.
How to wash Merino Wool thermals
Merino wool thermal underwear is usually a mix of merino wool and polyester, which tends to be less itchy on your skin than 100% wool. The mix of materials makes the underwear more durable and is easier to wash and keep clean.
To prevent bobbling, especially if there is print on the underwear, turn inside out before washing.
Machine wash on a low to medium heat setting ( 30 degrees ).
Wash separately where possible, or with similar colours.
Always use a mild detergent, but avoid any fabric softeners as they reduce the merino wool’s ability to actively manage your body temperature and build up of moisture by sticking to the fibres. In addition, fabric softeners also can make the garment start to bobble.
Ideally dry lying the underwear flat unless the care instruction on the label allows you to tumble dry. If you do tumble dry the garment make sure it is on a low heat.
You probably won’t need to iron your thermal underwear, but if you do then make sure it is on a cool or wool setting.
Don’t dry clean your thermal underwear
Tips for washing merino wool garments by hand
1) Use warm water and soap in a bowl, but avoid soaking the underwear as this could cause it to shrink and change shape.
2) If you notice any stains on your thermal underwear then use a damp cloth and dab the area. Avoid rubbing as this will damage the material.
3) Reshape the garments whilst they are damp, but don’t wring them out as this will shrink the merino wool.
4) Dry the thermal underwear on a flat surface, such as a large towel. Don’t peg the underwear out on a washing line or clothes hanger as the wool garment will stretch and lose its shape.
You can wash cotton thermal underwear either by hand or machine.
By hand, wash in warm water and use a mild detergent. Gently soak to remove any stubborn stains and rinse.
Try to air dry the thermals by spreading out on a flat surface. Avoid hanging them up as the fabric will start to lose its shape and stretch.
If you choose to machine wash your thermals then use the wool or delicate cycle of the machine. Again, use a soft detergent on a cool / warm wash.
Synthetic fabrics are usually made using polyester mixed with another material like polypropylene. You might also see nylon or a blend of other fabrics in your thermal underwear.
Elastane, spandex and Lycra are essentially the same style of a synthetic fiber made from polyurethane. Generally they are mixed with other materials and provide good comfort and elasticity for your thermals, as well as providing the right amount of heat retention and moisture wicking properties.
For best results wash your synthetic fabrics inside out. You can either machine wash or by hand, but always best to check the care label on the garment to ensure that you wash at the right temperature.
They tend to dry quickly and are normally okay to put in a tumble dryer or you can hang out to dry. Easy to care for they maintain their original shape well.
Silk is a strong natural material, and although not as effective as synthetic fabrics or merino wool, is lightweight, thin and a very effective insulator.
You can hand wash silk thermal underwear, or use the delicate cycle on your washing machine. Use a silk or wool enzyme free detergent.
Try not to wash your silk thermals too often, although silk stays fresh much longer than other materials due to its smooth shiny silk fabric.
