Frequently Asked Questions
Q: Does this men's thermal base layer set run true to size?
A: This thermal underwear set uses Asian sizing, which typically runs 1–2 sizes smaller than European or Western sizing. We recommend using the height and weight size chart provided to select the best fit. When in doubt, sizing up will give you a more comfortable, slightly looser layer. Contact us with your measurements if you need additional guidance.
Q: Can I wear this compression thermal set for outdoor winter running?
A: Absolutely! This set is specifically designed as a sport base layer for cold-weather activities including running, jogging, hiking, and gym workouts. The polyester-elastane blend offers four-way stretch and moisture-wicking properties, while the thermal lining provides insulating warmth — making it an ideal first layer under outerwear during autumn and winter.
Q: How should I care for my thermal underwear set?
A: For best results, machine wash on a gentle or cold cycle and avoid high-heat drying, which can degrade the elastane fibres and reduce stretch and fit over time. Tumble dry on low or lay flat to dry. Do not bleach or iron directly on the fabric.
