Danish sports brand hummel has collaborated with Tatsunori Otsuka, a player for Power Volley Milano. This is a triple collaboration that uses “MOON-TECH® nature,” an advanced material developed by MOONRAKERS, a spin-off venture from Toray. Pre-orders will be accepted until May 10th, with shipping scheduled for the end of June.
**A Message to Fans: Be Yourself**
This collaboration project began with the desire of an athlete, who usually receives support, to send a message of encouragement to their fans, based on the themes of Hygge (Danish for “cozy and warm time”) and Empowerment, which vitalizes daily life. Beyond being just a cheering good, the aim was to create a piece that allows fans and athletes to connect with a “comfortable sense of unity” and feel energized by wearing the athlete’s message in their daily lives.
Tatsunori Otsuka’s message, a player for Power Volley Milano, is 『Vær dig selv.』 (Be Yourself) in Danish. Regarding this phrase used on the back print, he said, “I often feel in sports that comparing myself to others doesn’t lead to anything good. Instead, I believe that valuing my strengths and living true to myself enriches life, and that’s a phrase I cherish.”
He aimed for a design that is “simply simple and wearable by anyone, so I considered the color scheme, word placement, and size to make it look simple. For the signature ‘tatsu,’ I chose the best one from many variations I wrote,” aspiring for a design that can be worn by many fans regardless of age or gender.
The material used is “MOON-TECH® nature,” an advanced material with “excessive functionality,” primarily featuring advanced space technology (powerful deodorizing and anti-fouling processing) developed to make life in extreme environments like space (International Space Station) more comfortable. It boasts 12 functions at a very high level, including natural texture, deodorizing, sweat stain prevention, anti-transparency, and UV cut. Furthermore, its quick-drying property, which allows it to dry almost immediately after dehydration during washing, is a convenient feature for expeditions and travels. It is a話題 of material that transforms daily life into the future with its overwhelming performance.
The collaboration T-shirt is available in two colors: white and charcoal. Pre-orders start on May 5th and will be accepted for a limited period until May 10th at the hummel official online store, hummel EXPOCITY store, and hummel Lalaport Kadoma store. Additionally, those who order during the pre-order period will receive an image for their smartphone wallpaper. Fans can feel Otsuka’s energy even from their daily smartphones.
