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 freezing temperatures along the entire 42-kilometer racecourse. This led 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 a race.

Designed for wet and cold climates, it uses Janerino® Merino tech wool fabric. Advanced textile technology perfectly blends fine, soft Australian Merino wool with synthetic fibers. The improved Merino wool fabric offers enhanced functionality, durability, and comfort.
The ultra-lightweight Janerino® wool is the best training top for all seasons. In cold winter, it provides excellent quick-drying, sweat-wicking, and odor-suppressing effects. Even if the clothes get soaked with sweat in winter, they can still keep you warm and prevent body heat loss. Through long-distance testing, the entire garment does not become heavy due to sweat, which would otherwise affect race performance.
Utilizing military-grade ripstop and water-repellent fabric, with reinforced拼接加強 (spliced reinforcement) at 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, asymmetric front and back hems, and side tassel design are all aimed at making the overall look more proportionate and stylish.
The ultra-lightweight care label is sewn on the outside to prevent friction against the body, and it can also be flipped to be hidden if you don't want it exposed.
The exposed small pocket is large enough to hold banknotes, credit cards, etc.
The classic hang tag can be reused as a coaster, and the packaging bag is also recyclable.
