Interval T-shirt
Every pace has a purpose.
The Interval T-Shirt is made for the moments between max effort and full control—where runners refine their rhythm, push their threshold, and build what lasts.
Crafted from a high-performance 73.31% cotton / 26.69% Sorona® blend, it offers natural softness with modern functionality. Sorona® provides stretch, shape retention, and moisture control—built to move with you through every mile, every interval, and every grind.
• Relaxed athletic cut with freedom to move
• STENOS FITNESS RUNNING TEAM arch graphic on the back
• Chest hit: Stenos Fitness / What We Think We Become
• Lightweight feel with durable structure
• Anti-shrink, anti-fade fabric tech
• Sorona® stretch fibers for optimal performance
This isn’t just a training tee.
It’s your uniform for the runners who think different, train harder, and lead with discipline.
Because the interval is where the work gets done.
