Nike Côte D’Ivoire Pro Elite 2019 Polo

The kit nobody sees on TV

A team t-shirt is the training and travel piece of an issued athletics kit — worn in the hotel, the bus and the warm-up area, never in the race. It carries the same federation badge as the competition kit, in street sizing and heavier knits.

The modern issue is polyester — 50 of the 56 tees in this archive declare it — because cotton holds twenty times the moisture. Cotton survives at the travel end of the set, where nobody sweats and softness wins.

The team tee is the piece of an issued kit that never starts a race. It is what athletes wear in the hotel, on the bus, in the food hall and through the warm-up — the working uniform of everything around competition. It carries the same federation or team badge as the race kit, which is why it belongs to the same issued set and why collectors treat it as kit rather than merchandise.

The rule

World Athletics TR5 covers the race uniform only — the tee sits outside it

The fibre

Polyester: regain 0.4% vs cotton's 8.5% at 20°C / 65% RH
