Men's Polypro Thermals

What is polypro and what are the benefits?

Polypropylene is a reliable, hard-wearing material that has been used for manufacturing thermals for decades. It is an extremely lightweight fibre with a high warmth-to-weight ratio, and has excellent resistance to tearing and abrasion, making it well suited to garments designed to be worn as a base layer. It is also moisture-wicking and fast drying, keeping you warm and comfortable while you adventure into the great outdoors.

Are men's polypro thermals suitable for wet weather?

Thermals are designed to be worn next-to-skin as a base layer under the rest of your adventuring get-up. While polypropylene is fast drying and wicks sweat from your body, its performance will be diminished in direct contact with rain. So you can wear them in wet weather, as long as you have a hard-shell outer-layer, like a rain jacket or softshell jacket, with waterproof properties.

Are men's polypro thermals good in cold weather?

Polypropylene provides thermal regulation, due to its low thermal conductivity that protects from external temperatures and reduces body heat dispersion. It also draws moisture away from the skin for ease of evaporation, and is quick drying so you don't' get that damp feeling during activity. With these properties, it is an excellent fabric for base layer undergarments in cold weather activities where you need extra warmth, from everyday use to alpine adventure.
