Three Dharma robes

The three dharma robes (Tib. ཆོས་གོས་རྣམ་གསུམ་, chögö nam sum, Wyl. chos gos rnam gsum) —

1. Saṅgati (Skt.; Tib. སྣམ་སྦྱར་, nam jar, snam sbyar), a large patched shawl made of 32 patches, usually yellow in the Tibetan tradition, worn only by fully ordained monks.
2. Uttarāsaṅga (Skt.; Tib. བླ་གོས་, la gö, bla gos), a large patched shawl, usually yellow in the Tibetan tradition, which can be worn by both fully ordained monks and novice monks, often called chögö nowadays.
3. Antarvāsas (Skt.; Tib. མཐང་གོས་, tang gö, mthang gos), the lower robe of a fully ordained monk, sown in pieces.

These three robes are part of the thirteen items of livelihood for monks as prescribed by the Buddha in the Vinaya.
