The fabric used in thermals is most often either cotton or wool blend. Generally it is made up of a two-ply fabric, that is, a wool layer and an artificial fiber-wool. In certain areas like US, both the layers are made up of artificial fibers to trap more body heat.
Inner thermal wears are worn exclusively in winters to keep the body warm and cozy. In the colder regions, thermal underwears are worn in place of traditional pyjamas as they are a lot more warmer than the flannels or regular cotton pyjamas. Interestingly, at times people also wear thermal clothes to avoid lengthy electricity bills resultant of heaters and blowers.
The most common style of winter thermal wears are long sleeve shirts along with long pants. Being thin fabrics, these are easily worn under jeans, shirts and other outer wears. Though the traditional long johns are rendered perfect for colder seasons but at times there are certain designer wears with which the long sleeved thermal inner wears cannot be worn thus, for such purposes sleeveless thermals wears are also extensively available in markets. Short sleeved mens thermal underwear are perfect to wear under casual dress shirts.
