Blo-warm vest

Abstract

A garment including a one-way inlet line including a desiccant to remove moisture from the user's breath, the inlet line being connected to a chamber formed by at least a portion of the front and back of the garment. The line extends through a portion of the garment to a designated location where warm air from the user's breath is distributed in the chamber. There is a second valve that the user operates to release the contained air, such as when one goes inside or when one wants to replenish the warm air after a period of time has passed.

1 . A garment device for providing warmth to a user in a cold environment, comprising:
 a chamber formed by at least a portion of the front and back of the garment;   an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line extending into the chamber to a designated location where the user's breath is distributed in the chamber, the inlet line including a check valve inside the chamber to prevent flow of air back out the open end line of the inlet line and the check valve includes a desiccant air dryer to remove moisture from the user's breath;   a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
     
     
         2 . The device of  claim 1 , wherein the chamber is formed from an air and water impermeable material. 
     
     
         3 . The device of  claim 1 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
     
     
         4 . The device of  claim 1 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line between the check valve and the release valve. 
     
     
         5 . The device of  claim 1 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
     
     
         6 . The device of  claim 1 , wherein the garment is sized to be worn under other garments. 
     
     
         7 . A method for providing a garment to provide warmth to a user in a cold environment, comprising the steps of:
 forming a chamber by at least a portion of the front and back of the garment;   providing an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line being positioned to extend into the chamber to a designated location where the user's breath is distributed in the chamber, the inlet line including a check valve inside the chamber to prevent flow of air back out the open end of the inlet line, the check valve including a desiccant air dryer to remove moisture from the user's breath; and   providing a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
     
     
         8 . The method of  claim 7 , wherein the chamber is formed from an air and water impermeable material. 
     
     
         9 . The method of  claim 7 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
     
     
         10 . The method of  claim 7 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line between the check valve and the release valve. 
     
     
         11 . The method of  claim 7 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
     
     
         12 . The method of  claim 7 , wherein the garment is sized to be worn under other garments. 
     
     
         13 . In a garment device for providing warmth to a user in a cold environment wherein the garment has a front and back portion, the improvement comprising:
 forming a chamber from at least a portion of the front and back of the garment;   positioning an inlet line having an open end proximate the user's mouth and positioned for receipt of the user's breath, the line including a check valve inside the chamber, the check valve including a desiccant air dryer to remove moisture from the user's breath, the check valve positioned to prevent flow of air back out the open end of the inlet line extending into the chamber to a designated location where the user's breath is distributed in the chamber; and   placing a release valve in communication with the chamber and operable to maintain the chamber in a closed condition holding the user's breath therein and an open condition to release the user's breath when desired by the user.   
     
     
         14 . The device of  claim 13 , wherein the inlet line includes. 
     
     
         15 . The device of  claim 13 , wherein the chamber is formed from an air and water impermeable material. 
     
     
         16 . The device of  claim 13 , wherein the garment includes a front portion and back portion that are joined together to form the chamber. 
     
     
         17 . The device of  claim 13 , wherein the inlet line further extends from the release valve to a to a release point proximate the user's back. 
     
     
         18 . The device of  claim 13 , wherein the inlet line includes a plurality of holes in at least the portion of the inlet line downstream of the check valve.
