For those of you who want to keep your winter essentials negligible but don’t want to compromise on the warmth factor, here’s the perfect list of the best thermals for men. These retain warmth for a long time and remain unaltered even after prolonged exposure to the most frigid climates. 

Our research indicates that men tend to have more sweatpores and a rougher skin texture than women. When men shop for thermals, they usually search for products with superb elasticity, and a breathable texture, and do not color fade with every washing use (1).

Thermals and base layers may perform the same function of retaining and amplifying body heat, but there is an underlying difference between the two. Base layers help to keep the body dry and prevent the occurrence of sweat infections only, whereas thermals help to retain the body’s natural heat and prevent the numbing of muscles due to prolonged exposure to the frosty climate outside. Moreover, thermals have a protocoled layer of thickness, and base layers can be lightweight and ultra-weight. 

Thermals help save space by eliminating the need for additional woolen clothes. But a premium-quality thermal should not cause a hole in your pocket or trigger genetically inert infections and allergies. Hence, our team of in-house fashion experts has picked the bestsellers from the market and curated a list of the best options that can fit all body shapes and sizes.

Choosing the best thermals for men is a tiring exercise as every brand tries to showcase itself via social media marketing and offline advertisements as one of the “best” in the market. However, here are a few factors you can consider while picking the warmest thermals for your man. 

1. Composition
   Thermals for men need to have a snuggly stretchable fit to adjust, and should not consist of harmful polyesters and harmful dyes as they may cause extensive itching and even lead to infections that can be detrimental in the future. Moreover, the product should also be made of soft breathable material to not affect and aggravate existing sweat infections and cause rashes. 
2. Texture
   The texture of the clothing should be breathable, lightweight, and washable and should consist of strongly woven fibers as it may otherwise cause withering of the cloth and may cause gradual deterioration and simultaneously cause the cloth to diminish and lose shape with very gradual wash. 
3. Body Shape and Size
   Just like women, the shape of a man’s body differs accordingly the varying shapes of a man’s body are trapezoid, triangle, square, oval, and inverted triangle. For men with a rectangle-shaped body, the length of the shoulders and the torso remains the same, hence one needs to look for a fit with a wide shoulder. Whereas for a triangle-shaped body if anyone is selecting for lower waist thermals the cloth should have a wider length. 

Maintaining thermals and helping them retain their shelf life may seem like a tough and time-consuming process but with these tips, you can ensure they remain durable.  

1. Wash the thermal with a mild detergent 
2. Make use of fabric softeners post-washing to retain the texture that has been lost.  
3. Dry them out in the sun to prevent the growth of bacterial and fungal elements and the formation of a foul odor. 
4. Read the instruction manual carefully, to check whether it is compatible with hand wash and machine wash. 
5. If it is compatible with handwash use a mild detergent and spot removers to get rid of stubborn stains.
