A jinbei (甚平) (alternately jinbē (甚兵衛) or hippari (ひっぱり)) is a traditional set of Japanese clothing worn by men, women and children during summer as loungewear.
However, unlike kimono, jinbei typically do not have an overlapping front panel (known as the okumi), and feature two sets of ties – one inside and the other outside – to fasten the top shut.
Traditional jinbei are made from hemp or cotton, and are typically dyed a solid colour – such as indigo, blue or green – with either a muted or nonexistent pattern.
Jinbei seams are very loosely sewn to allow for ventilation during hot weather, and from a distance appear to form a short gap between different fabric pieces.
Normally, jinbei are typically only worn outside the house when travelling short distances, such as to go on a local errand, collecting the mail or while shopping.
