The oldest Rosa & Co. kit in our archive comes from the group's hottest streak: three seasons in which its athletes took a sixteen-year-old world record apart in Chicago, won London twice over and stacked half marathon records like firewood.
2019 opened with Ruth Chepngetich's 2:17:08 course record in Dubai in January; what she did in Doha that autumn was done in Kenya's federation kit and lives in our Kenya 2019 page. On 13 October Brigid Kosgei, raised in the group's Kapsait camp, ran 2:14:04 in Chicago: Paula Radcliffe's world record, 16 years old, gone by 81 seconds. Kosgei had already won London that spring as the youngest champion in the race's history.
The pandemic year narrowed to one bubble in St James's Park — and the group took it over: Kosgei defended London (2:18:58) with Chepngetich third.
A half-zip jersey is the mid layer of an issued athletics kit: a stretch polyester knit with a high collar and a sternum-length zip, worn for cold-weather training and around the stadium.
The zip is the point: a quarter open over a warm-up, closed to the chin in a cold call room. It is the only garment in the kit with a thermostat, and the most wearable piece a team ever issues.
Thermal engineering has a unit for what it does.
What the jacket cannot do is the zip. A quarter of the way open over a warm-up, closed to the chin in a cold call room, half down on the bus — the half-zip is the only garment in the kit with a thermostat.
Layering guides put every cold-weather outfit together the same way: a wicking base against the skin, an insulating mid layer over it, a shell on top when weather demands.
