The Common Swift - a fascinating flyer that sleeps, hunts, drinks, rests and even mates in flight. It has always been abundant in Czech towns and villages, but in recent decades it has suffered a massive decline in nesting sites due to insulation and reconstruction of buildings (for example, in Prague it has declined by more than 45% from 1989 to 2000!). By buying a 100% cotton basic T-shirt with a print of a swarm, BUSHMAN and CSO logos you will be contributing 12 EUR to the protection of these beautiful birds. Weight: 180 g/m2.
