Training when it is over twenty five degrees

Short answer: In heat, no fabric can keep you dry. Choose thin and loose, drink more than usual and move training to morning or evening.

Evaporation is what cools

Sweat only cools when it evaporates. Loose clothing with air around it makes that possible. See bamboo t-shirts for men.

Thin beats technical

A thin layer that moves moisture beats a thick technical fabric in heat. Weight matters most. See bamboo shorts for men.

Timing matters more than clothing

Seven in the morning is often ten degrees cooler than three in the afternoon. That changes more than any material choice. See bamboo training clothes for women.

Frequently asked questions

What is best to train in when it is hot?

Thin, loose clothing that lets air reach the skin and moves moisture away.

Does material help in heat?

A little. Timing, pace and fluid matter more than fibre choice.

Should you train in the heat at all?

Move training to morning or evening instead, and lower the pace in the middle of the day.
