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. This led him to spend a full year developing an excellent winter running shirt that could keep the body warm in bitter winds and help achieve peak performance during the race.

Designed for damp and cold climates, it uses Janerino® Merino tech wool fabric. Advanced textile technology perfectly combines delicate and soft Australian merino wool with synthetic fibers. The improved merino wool fabric offers greater functionality, durability, and excellent comfort.
The ultra-light Janerino® wool is suitable for all seasons and is the best training top. In cold winter, it offers excellent quick-drying, moisture-wicking, and anti-odor effects. Even when wet, it keeps you warm and prevents body heat loss. Through long-distance testing, the entire shirt does not get heavy from sweat, preventing it from affecting race performance.
Utilizing military-grade tear-resistant and water-repellent fabric, reinforced panels are strategically placed on high-friction areas such as elbows and shoulders. This provides an extra layer of protection, especially when carrying a backpack outdoors.
The dropped-shoulder oversized fit, asymmetrical front and back hems, and side tassel design are all meant to make the overall look more proportionate and stylish.
The ultra-light information wash tag is sewn on the outside to prevent rubbing against the body, and it can also be flipped and hidden if not desired to be exposed.
The exposed small pocket is sufficient for cash, credit cards, etc.
The classic hangtag can be reused as a coaster, and the packaging bag is also recyclable.
