If you are unsure, feel free to contact us with your measurements and we'll help you find the best fit.
Q: Is this thermal underwear set suitable for outdoor sports in cold weather?
A: Yes! The polyester-elastane compression fabric is designed to retain warmth while wicking moisture away from the skin quickly. It's an ideal base layer for running, skiing, hiking, cycling, and other cold-weather activities, keeping you comfortable and dry throughout your workout.
Q: Can I wear this thermal underwear set as an everyday base layer under regular clothing?
A: Absolutely. The slim, compression-fit design means the set sits close to the body and layers seamlessly under jeans, trousers, or work attire without adding bulk — making it just as practical for everyday winter warmth as it is for sport.
