46-year-old parolee Steven Dwayne Paulson, of Pomona, was arrested on Jan. 10 in Upland.
The nickname came from a ski parka that the suspect wore during several of the robberies.
The robberies began on Dec. 20 at a U.S. Bank branch in Chino.
Police say Paulson then hit banks in Corona, Lake Elsinore, Glendora and Cerritos, as well as the same Chino bank again on Jan. 7.
The last robbery was at a Rancho Cucamonga Comerica Bank branch on Jan. 9.
Most of the time, the suspect used a demand note. In some of the robberies, he also motioned to indicate he had a gun under his coat.
Authorities say more than $43,000 was stolen in the robberies.
