During a marathon race, founder Johnny Ku experienced a 42-kilometer sub-zero temperature course. This inspired him to spend a full year developing an excellent winter running shirt that could keep the body warm in biting cold winds and help achieve peak performance during the race.
During a marathon, founder Johnny Ku experienced a 42-kilometer race in freezing temperatures. This led him to spend a full year developing an excellent winter running top that could keep the body warm in biting winds and allow for peak performance during the race.


Designed for humid and cold climates, it uses Janerino® Merino tech wool fabric, which perfectly combines delicate, soft Australian merino wool with synthetic fibers through advanced textile technology. The improved merino wool fabric offers greater functionality, durability, and excellent comfort.

The ultra-light Janerino® wool is the best training top for all seasons. In cold winters, it offers excellent quick-drying, moisture-wicking, and anti-odor effects. Even when soaked with sweat in winter, it can keep you warm and prevent body heat loss. Through long-distance testing, the entire garment does not become heavy due to sweat, which could affect race performance.

Using military-grade tear-resistant, water-repellent fabric, reinforced panels are added to high-friction areas such as elbows and shoulders, providing an extra layer of protection, especially when carrying a backpack outdoors.
The dropped shoulder oversized fit, asymmetrical front and back hemlines, and fringed side hemlines are all designed to create a better and more stylish overall proportion when worn.
The ultra-light information tag is sewn on the outside to prevent friction against the body, and it can also be flipped to hide if desired.

The exposed small pocket is sufficient for holding cash, credit cards, etc.

The classically designed hangtag can be reused as a coaster, and the packaging bag is also recyclable.
