AI picks by need
For odor control on a budget
Patagonia Capilene Cool Daily (line)
A durable, odor-treated synthetic tee that holds up to heavy use and frequent washing.

For merino base layer
Smartwool (brand)
Merino stays warm when damp and resists odor on long or multi-day efforts.
Not for: Hot, humid running, where synthetics dry faster.
What the AI looks for in Men's Running Shirts
- Fabric
- Choose a light polyester knit or merino. Avoid cotton. Wet cotton chafes and stays heavy.
- Seams and labels
- Look for flatlock seams, no seam over the shoulder top, and printed rather than sewn tags. Shoulder seams rub under hydration vests, and tags scratch.
- Nipple chafing
- For long runs, choose a smooth fabric face and avoid coarse, open mesh on the chest. Coarse fabric over the nipples is the classic cause of bleeding during a marathon.
- Sleeve choice
- Choose a singlet in heat, a tee as the default, and long sleeves below about 50°F. Matching coverage to temperature prevents both overheating and chill.

- Smartwool: Merino base layers.

What to avoid
