In recent years StickerBib adhesive bibs have been gaining popularity across Europe and the United States, StickerBib adhesive bibs were used for the first time at this year's World Athletics Diamond League Shanghai/Kechiao meet, making it one of the few Asian meets to adopt this technology at a top-level athletics event.

The new technology features a full-coverage adhesive backing so athletes simply peel off the liner and stick the bib directly to their race clothing—no pins required. It stays flat and secure during high-speed running, improving fit and aerodynamics while simplifying pre-race preparations.

Its debut in the Diamond League drew attention, particularly around whether it can maintain stability under the high-intensity conditions of sprint and middle-distance races, making it one of the technical highlights of this year's Shanghai leg.

StickerBib's core design replaces the traditional Tyvek bib with a full-surface adhesive backing. After check-in, athletes simply peel off the backing and stick it directly onto their race kit. Compared with traditional pin-on bibs, the adhesive bib prevents garments from being pierced and reduces flapping and noise during high-speed running, offering stability advantages for sprints, hurdles, and distance events.

Several European road races, cross-country skiing events, and triathlons have already used similar technology, but this is the first large-scale use in a top-level World Athletics event.

The Diamond League Shanghai/Keqiao meeting chose to adopt StickerBib this year. The main considerations included the variety of athletes' kit materials, the stability of broadcast visuals, and the international events' demand for attention to detail. As elite athletes' race kits become thinner and more elastic, traditional pin-on bibs can easily cause wrinkling or displacement when secured, while adhesive bibs keep numbers flat throughout the competition, which helps both broadcast images and officials' reading.

In addition, adhesive bibs can reduce the time athletes spend adjusting their numbers before a competition and prevent discomfort caused by loose pins, incorrect angles, or pinching the skin. For athletes who need to complete check-in, warm-up, and call-up procedures in a short time, this change can simplify pre-event preparation.

The introduction of StickerBib is also seen as a new step in accessory technology for athletics events. Over the past decade, carbon-plated spikes, lightweight racing kits and electronic pacing systems have gradually appeared on the track, and now bibs are entering an update phase. StickerBib has made its first appearances in sprints, hurdles and middle- and long-distance events; usage at the Shanghai/Keqiao stop will serve as an important reference for World Athletics events and other Diamond League venues, making it one of the season's most talked-about technical updates.

Do you think this race bib is breathable? Would you be willing to use this type of bib for a marathon or for trail running?
