Patent ID: 6904617

Claim:
A wear, comprising: an outer layer; an inner layer overlapped with said outer layer to form a storage compartment; a thermal lining, which comprises: a construction pocket shaped and sized to receive in said storage compartment of said wear, wherein said construction pocket, which is detachably disposed in said storage compartment, comprises a first layer made of fabric adapted for water permeating therethrough and a second layer overlappedly attached to said first layer in an edge to edge manner; and a cooling agent, having water absorbing ability, disposed in said construction pocket to form a heat insulation layer between said first and second layers, wherein said cooling agent is adapted for absorbing water and evaporating said water so as to provide a cooling effect of said wear such that only water is allowed to permeate through said first and second layers, wherein said cooling agent is a solid resin disposed in said construction pocket, wherein when said cooling agent is soaked with said water, said water is absorbed by said cooling agent to expand a size thereof and change a phase from solid to liquid so as to form said heat insulation layer, and when an ambient temperature is increased, said heat insulation layer starts to exchange heat energy by evaporating said water in said cooling agent, wherein said first layer is made of fabric having ventilating properties and durability, said first layer being adapted for water permeating into said construction pocket, so as to retain a shape of said cooling agent in said construction pocket after said cooling agent is expanded to form said heat insulation layer; and a plurality of cap leaves attached edge with edge together to form a cap body, wherein said storage compartment is formed at each of said cap leaves, wherein said outer layer is overlappingly attached to said inner layer to form each of said cap leaves, wherein an inlet opening is formed at one edge of said cap leave for communicating said storage compartment with outside so as to receive said thermal lining in said storage compartment, thereby, said inner layer of said wear keeps said water absorbed by said cooling agent within said construction pocket for preventing said water from being permeated through said inner layer of said wear when said wear is worn.
