Men's S-TUOLUMNE RIVER - UPF 50+ Performance Singlet
Breathable UPF+ 50, recycled knit for cool, dry comfort - More Info

A singlet that takes sun protection as seriously as sweat management.

The S-Tuolumne River is Fractel's Coolcore Tyndall singlet in blue, cut for maximum airflow through the chest and back. UPF 50+ sun protection and four-way stretch handle the heat, with reflective details for early starts.

  • Coolcore Tyndall recycled fabric: UPF 50+ across every panel, with lightweight, moisture-wicking cooling
  • Sleeveless cut with a relaxed fit: four-way stretch opens up airflow through the chest and shoulders
  • Reflective details: added visibility at dawn, dusk or low light
