Cloud Waffle Base T‑Shirt is versatile and resilient in all types of weather and conditions. In colder weather, the wool naturally retains your body heat to sustain warmth and performance throughout trips of any duration. Unlike most fabrics, even when Cloud Waffle Base T‑Shirt is wet, it will keep you warm.

- Runntex is made in Japan from 100% Optimo wool. The factory was founded in 1964 and is known for its high gauge jersey and innovative natural fabrics. The wool's porous fibers lift sweat away from your skin so you never feel clammy on a run and dries quickly in wet conditions since the creases of the wool trap your body's heat. Finely knitted, Cloud Waffle Base T‑Shirt is ultra lightweight, silky soft and naturally odor resistant. Its thermoregulation properties and moisture management capabilities make it an ideal fabric for use throughout the varying seasons, providing continuous comfort all year round.

- Ultra-lightweight 100% Optimo wool (thermoregulation, silky soft, odor control, natural elasticity) fabric.
- Regular fit.
- Grid patterns in the fabric provide both insulation and breathability at the same time.
- Flatlock seam construction across the garment allows for a frictionless experience.
- Exterior detachable care label so nothing rubs against your skin.
