Run 2 Travel Design: The Story
Every project tells a story, and this Lightweight Merino T-Shirt is no exception. Designed by Invisible, born from our collaboration with The Peak Hunter – the elite trail running crew led by Hong Kong's own Wong Ho Chung—the "Run 2 Travel" world map isn't just a design; it's an invitation to explore long run. This graphic captures the spirit of running to discover new territory. The world map, complete with GPS coordinates (familiar GPX touch for every runner!), symbolizes the journey from Hong Kong out to the world. Notice the subtle folded right corner? Not only representing the logo of The Peak Hunter, it's like a well-used passport page or a cherished notebook entry – a nod to adventures completed and new destinations waiting. Adding our signature touch, the Pau Yau (跑遊) logo is sewn on the right hem, a symbol of our shared journey with you.
The Power of Merino
Merino Wool is a protein-based fiber, specifically, keratin, just like your hair. Each fiber’s natural crimp traps air, creating insulating pockets for exceptional thermoregulation. Its “dual naturel” also gives it incredible moisture control—the fiber feels dry on the outside, yet absorbs vapor from your skin.
