All-New Adidas 2026 World Cup Training Template Leaked - First Look at Japan Edition

Footy Headlines can exclusively reveal the all-new training kit template that Adidas will use for all its national teams at the 2026 World Cup. Our first look comes via the new Japan 2026 training jersey.

All-New Adidas 2026 World Cup Training Template

The new Adidas 2026 World Cup training template features significant changes compared to the 2024 and 2025 versions, starting with the design.

The new 2026 template features large, wide panels on the shoulders and under the arms, a major departure from the thin side panels that ran down to the hem in previous years.

The Adidas 2026 training kit introduces the new Climacool+ technology, which will replace the current HEAT.RDY and AEROREADY systems, marking a significant upgrade for the brand's training apparel.

The new template is packed with new features:

• New Fabric: The fabric is brand new. The chest and side areas feature a checkered pattern of tiny squares, designed for targeted ventilation and breathability.

• New Tech Name: The branding on the inside confirms the return and upgrade of a famous name: 'Climacool+'.

• New Stripes: The iconic Three Stripes on the shoulders have been updated with three lines of stitching integrated directly into them. This not only creates a unique 'stripe-in-stripe' look but may also aid breathability.

The new Adidas 2026 World Cup training kits will be launched in November 2025. Each national team, like Japan, will receive the template in their own unique colorway.
