What To Consider When Buying Thermal Leggings


Looking for moisture-wicking fabrics will mean you keep warm and dry even in the cold.

Synthetic materials are usually durable and elastic and great for activewear.

Merino wool is super warm but not as moisture wicking. It does have natural antibacterial properties.


Look for leggings that fit snugly but don’t constrict. You don’t want them falling down or feeling loose.

Also opt for seamless or flatlock seams that don’t chafe or irritate when exercising.


Thermal leggings come in lightweight to heavyweight materials. These provide warmth against cold and freezing temperatures.

Depending on what you are using your leggings for you may want to choose either, or.
