Hot yoga means sweating a lot, so what you wear changes how the class feels. Moisture-wicking fabric is made for that. Here is how it works, why people choose it for a heated room, and what to look for in yoga clothes.
How moisture-wicking fabric works
Moisture-wicking fabric works through capillary action. This is the same effect that lets water climb a paper towel dipped in a glass. The fibers attract water, so sweat is drawn away from your skin, through the fabric, to the outer surface where it can evaporate.
Why people choose it for hot yoga
In a heated room you sweat a lot. Many people prefer clothes designed to move that sweat off the skin, because they feel less damp and sticky than clothes that hold it.
Comfort. Wicking fabric is designed to reduce moisture sitting against the skin, which can make clothes feel less clingy.
Evaporation. The body sheds heat mainly by sweat evaporating, and clothing can get in the way. Wicking fabric is designed to let sweat evaporate from its outer surface.
One honest limit: independent research has not conclusively shown that wicking clothes improve cooling or performance, and at low to moderate effort synthetic garments were no better than cotton in the studies reviewed. Treat it as a comfort choice, not a guarantee. Source: Sport Information Resource Centre, 2018.
Choosing the right yoga clothes
Quality. Fabrics are not all equal. Look for brands that are open about what their fabric is made of and that have solid reviews.
Fit. Wicking depends on the fabric touching the skin, so a fairly close fit works best. You also need to move freely, so check that you can fold, twist and balance in it before you commit.
Purpose. A hot class calls for light, breathable pieces. A cooler studio, a morning outdoors or the trip home may call for a layer on top. Some brands, such as Copper Fit, also make compression activewear.
The practical takeaway
Whatever you wear, the goal is to stay comfortable enough to focus on the practice, in a studio class or a teacher training.
