Product details

The W Mer 125 Cool-Lite Sphere III Tank from Icebreaker is a functional tank top specifically designed for athletic activities in warm conditions. Made from innovative Cool-Lite™ technology, it combines the benefits of TENCEL™ and merino wool to provide a lightweight, breathable, and quick-drying wearing experience. This shirt is not only soft and comfortable but also odor-neutral, making it ideal for longer outings. The offset shoulder seams minimize friction, especially when wearing a backpack, while the extended back provides additional coverage. With reflective details and a thoughtful design that promotes mobility and optimal fit, this tank top is the perfect choice for running, hiking, and other outdoor activities.

  • Cool-Lite™ material for breathability and quick drying
  • Offset shoulder seams reduce friction when wearing a backpack
  • Reflective details for better visibility in low light conditions
  • Ergonomic design with eyelet mesh for optimal ventilation.
