Amphibious self-bailing backpack

Abstract

A backpack includes a tight fitting wetsuit style vest with a low profile pack attached to the back. The backpack is configured with closures and compartments that are accessible when the backpack is worn. The backpack has a slight positive buoyancy enabling it to float with contents, but not enough to interfere with water activities. Mesh material allows water to readily escape from the storage compartments and prevents trapping of air in the compartments.

1 . A backpack comprised of a tight fitting vest, said vest being comprised of a stretchable material and having a front and a back, and a pack with at least one compartment attached to the back of the vest, said pack including a mesh bottom in fluid communication with the at least one compartment.  
   
   
       2 . A backpack according to  claim 1 , further comprising a zipper closure adapted to provide access to said at least one compartment.  
   
   
       3 . A backpack according to  claim 1 , further comprising a spring clip operably coupled to said backpack within the at least one compartment.  
   
   
       4 . A backpack according to  claim 1 , further comprising a material that provides a net positive buoyancy sufficient to maintain the backpack and its contents afloat in water but not sufficient to maintain a wearer afloat in water.  
   
   
       5 . A backpack according to  claim 1 , said at least one compartment being accessible while the backpack is worn.  
   
   
       6 . A backpack according to  claim 1 , said vest including a bottom inside band, said bottom inside band being comprised a material adapted to frictionally engage a wearer's waist.  
   
   
       7 . A backpack according to  claim 1 , further comprising a material that provides a net positive buoyancy sufficient to maintain the backpack and its contents afloat in water but not sufficient to maintain a wearer afloat in water; and said vest including a bottom inside band, said bottom inside band being comprised a material adapted to frictionally engage a wearer's waist.  
   
   
       8 . A backpack according to  claim 7 , further comprising a zipper closure adapted to provide access to said at least one compartment.

       11 . A backpack comprised of a tight fitting vest, said vest being comprised of a stretchable material and having a front and a back, and a pack with at least one compartment attached to the back of the vest, said pack including a self-bailing means in fluid communication with the at least one compartment.  
   
   
       12 . A backpack according to  claim 11 , further comprising a zipper closure adapted to provide access to said at least one compartment.  
   
   
       13 . A backpack according to  claim 11 , further comprising a spring clip operably coupled to said backpack within the at least one compartment.  
   
   
       14 . A backpack according to  claim 11 , further comprising a material that provides a net positive buoyancy sufficient to maintain the backpack and its contents afloat in water but not sufficient to maintain a wearer afloat in water.  
   
   
       15 . A backpack according to  claim 11 , said at least one compartment being accessible while the backpack is worn.  
   
   
       16 . A backpack according to  claim 11 , said vest including a bottom inside band, said bottom inside band being comprised a material adapted to frictionally engage a wearer's waist.  
   
   
       17 . A backpack according to  claim 11 , further comprising a material that provides a net positive buoyancy sufficient to maintain the backpack and its contents afloat in water but not sufficient to maintain a wearer afloat in water; and 
 said vest including a bottom inside band, said bottom inside band being comprised a material adapted to frictionally engage a wearer's waist.    
   
   
       18 . A backpack according to  claim 17 , further comprising a zipper closure adapted to provide access to said at least one compartment.
