Do thermal trousers work?

Yes, thermal trousers are designed to trap in heat from the body and provide an extra level of insulation, ultimately keeping you warm for longer periods of time.

Do thermals need to be tight?

Whilst thermals should be snug to the body, it is important to make sure they are not restrictive. A closer fit will ensure that the fabric has a better chance of insulating heat against the body.

Are base layers better than thermals?

Base layers tend to wick moisture away from the body, whilst thermals focus on insulating heat against the body. Base layers are better for active people who will sweat, whereas thermals are better for colder weather, where you do not require moisture to be wicked away from the body.

How often do you wash thermal pants?

You should wash your thermal trousers after several wears, however this does depend on activity level. Frequent washing can reduce the quality of the fabrics insulating properties, so follow the care instructions available on the label of your garment.

Do you wear anything under thermal pants?

Thermal pants are designed to be worn alone or over a base layer. Avoid wearing bulky layers underneath, as the closer your thermals are to your skin the better they will perform.
