The Men’s 2026 Detroit In-Train Atmos 3.0 Long Sleeve is built for runners staying locked into Detroit race training. This ultralight layer delivers near-weightless coverage with a smooth, comfortable feel that works perfectly on its own or layered as conditions change.
Quick-drying stretch fabric moves easily through every stride while helping manage sweat during steady miles and harder efforts. An odor-resistant finish helps keep the shirt feeling fresh between washes, and built-in sun protection adds extra coverage for long runs. Finished in a semi-fitted cut, this long sleeve is designed to move naturally through every phase of training.
This is the layer you trust when consistency matters most.
