noun
hood discarded in spring
A hood or head covering that becomes unnecessary when the weather warms up in spring, often associated with the seasonal transition.

It got warmer, so I put away the hood I no longer needed.
Compound of 捨て (sute, 'discarding') + 頭巾 (zukin, 'hood'). The exact historical derivation is uncertain.
