Frequently Asked Questions
Q: Is this men's thermal compression set true to size?
A: This set uses Asian sizing, which typically runs 1–2 sizes smaller than European or US sizes. We recommend checking the size guide above (height and weight recommendations) and sizing up if you are between sizes. If you are unsure, please contact us before placing your order.
Q: Can I wear this thermal base layer set for outdoor winter running?
A: Yes! The thermal polyester-elastane knit is designed to retain warmth close to the body while the quick-dry fabric wicks away moisture, making it well-suited for outdoor jogging, running, and cold-weather gym training.
Q: Does the set include both the top and the pants?
A: Yes, this listing is for a full set — a long-sleeve compression top and matching full-length thermal long johns pants, sold together as a complete base layer tracksuit.
Q: How do I care for this compression base layer set?
A: For best results, machine wash on a gentle cycle in cold water and hang to dry. Avoid bleach and high-heat drying to preserve the elasticity and shape of the fabric.
