Running Apparel FAQs:

Q: Are cotton shirts good for running?

Cotton shirts aren't ideal for running because they trap moisture, cause chafing, and dry slowly. For better performance, choose natural fabrics like merino wool that breathe, manage moisture, and resist odor.

Q: Is a tight or loose shirt better for running?

A fitted shirt is better for running. It reduces chafing, moves with your body, and helps regulate temperature more efficiently. icebreaker’s natural merino running shirts offer a close-to-body fit built for comfort, breathability, and performance on every run.

Q: Why do runners wear no show socks?

Runners wear no show socks for a minimal feel, reduced bulk, and a distraction-free fit. icebreaker running socks combine merino wool with targeted support and breathability, keeping feet cool, dry, and comfortable mile after mile.
