	"Young ice" is a transition stage between nilas and first-year ice, and ranges in thickness from to , Young ice can be further subdivided into "grey ice" – to in thickness, and "grey-white ice" – to in thickness. Young ice is not as flexible as nilas, but tends to break under wave action. In a compression regime, it will either raft (at the grey ice stage) or ridge (at the grey-white ice stage).
