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 the freezing cold conditions of the 42-kilometer race route. This led him to spend a full year developing an excellent winter running shirt that could keep the body warm in biting winds and allow for optimal performance during the race.


Designed for wet and cold climates, it uses Janerino® Merino tech wool fabric. Advanced textile technology perfectly combines fine, soft Australian Merino wool with synthetic fibers. The improved Merino wool fabric offers greater functionality, durability, and comfort.
The ultra-lightweight Janerino® wool is the best training top for all seasons. In cold winters, it offers excellent quick-drying, moisture-wicking, and anti-odor properties. Even when soaked with sweat, it keeps you warm and prevents body temperature loss. Tested over long distances, the garment does not become heavy from sweat, thus not affecting race performance.
Utilizing military-grade anti-tear and water-repellent fabric, with reinforced拼接 (splicing/patchwork) at high-friction areas like 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 side hem slits are all designed to create a better proportioned and more stylish overall look.
The ultra-lightweight care label is stitched on the outside to prevent rubbing against the body, and it can be flipped inwards to hide it if desired.
The external small pocket is sufficient for holding banknotes, credit cards, etc.
The classic design hangtag can be reused as a coaster, and the packaging bag is also recyclable.
