Interval Shirt

Q: Are synthetic shirts good for workouts?

Yes, shirts made from synthetic materials are excellent for workouts—as long as they feature key performance characteristics like moisture-wicking, breathability, stretch, and odor resistance. The Ten Thousand Interval Shirt uses a high-quality synthetic blend with a quick-drying, anti-odor treatment and strategic ventilation, making it ideal for intense training sessions.

Q: What material are workout shirts made of?

Workout shirts are typically made from synthetic materials like polyester or nylon, often blended with spandex for stretch. These fabrics wick moisture, dry quickly, and maintain shape during movement. The Interval Shirt features a sweat-wicking, quick-drying performance fabric designed to handle demanding training sessions.

Q: How tight should workout shirts be?

Workout shirts should offer a close-to-body fit without feeling restrictive. A properly fitted shirt improves mobility and moisture management while preventing excess fabric from getting in the way. The Interval Shirt provides an athletic fit—slim enough for performance but relaxed enough for comfort.
