Frequently Asked Questions
Q: Does this men's thermal underwear set work for sports and outdoor activities?
A: Yes! The quick-drying polyester-elastane blend and four-way stretch make this thermal base layer ideal for running, skiing, hiking, cycling, and gym workouts. The compression fit supports muscles during activity while the fabric keeps moisture away from your skin.
Q: Should I size up when ordering this thermal underwear set?
A: We recommend sizing up by 1–2 sizes compared to your usual European sizing, as this is an Asian-sized garment. Please refer to the height and weight size chart above for the most accurate fit. If you are between sizes, choosing the larger size will give you a more comfortable fit.
Q: How do I care for this thermal long johns set?
A: For best results, machine wash cold on a gentle cycle and hang to dry. Avoid high heat tumble drying or ironing, as this can damage the elastane fibres and reduce the compression properties of the fabric over time.
