Buying Thermal Singlets Online

A thermal singlet is part of the base layer of your running outfit. Thermal tank tops are highly-functional in winter as well as summer. In cold conditions, thermal clothing provides warmth by insulating body heat. In warm conditions, thermal clothing can help you stay ventilated. It is important to wear functional underwear when running in summer. A base layer singlet, for instance, wicks transpiration away from the body to the outside of the top where it can evaporate. Thus thermal underwear for summer keeps you cool and thermal underwear for winter keeps you warm.

Base layer running tanks are light in weight and fit close to the skin. Their tight fit helps to ensure that they absorb transpiration and drain this away to the outside of the thermal base layer. Singlets help you stay dry for longer and keep you from cooling down quickly, regardless of temperatures. This functionality of sports underwear is very important during running.

When it comes to thermal underwear there’s a lot of choice. In addition to singlets, you can also think of short and long underpants and tops with long and short sleeves. All of which provide thermal insulation. At 21RUN you will find thermal tank tops for men and women from various top brands such as Odlo, Craft and Falke.
