Freeze Defense is a men's 3 in 1 winter coat system ready to protect you in the winter. A fully insulated jacket and zip-out vest comprise the 3 in 1 Freeze Defense men's 3 in 1 jacket. Freeze Defense is versatile as well as functional. The coat can be worn separately from the vest, or when nature throws its worst, zip the vest into the coat and you have a very warm winter defense parka. Be ready for the cold!
