Abstract

An article of apparel may include a torso region with a front area, a back area, and a pair of side areas. At least a portion of each of the side areas are formed from a material with (a) a first air permeability when unexposed to water and (b) a second air permeability when exposed to water. The first air permeability may be less than 279 cm 3 /second per cm 2 measured in accordance with ASTM D 737, and the second air permeability may be greater than 279 cm 3 /second per cm 2 measured in accordance with ASTM D 737. In some configurations, at least a portion of the back area may be formed from the material. The article of apparel may be a shirt, and the article of apparel may include arm regions that extend outward from the torso region.

Claims

exact text as granted — not AI-modified
1 . An article of apparel comprising a torso region with a front area, a back area, and a pair of side areas, at least a portion of each of the side areas being formed from a material with:
 a first air permeability when unexposed to water, the first air permeability being less than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737; and   a second air permeability when exposed to water, the second air permeability being greater than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737.   
     
     
         2 . The article of apparel recited in  claim 1 , wherein the apparel is a shirt and includes a pair of arm regions extending from the torso region. 
     
     
         3 . The article of apparel recited in  claim 1 , wherein at least a portion of the back area is formed from the material. 
     
     
         4 . The article of apparel recited in  claim 3 , wherein the material has an elongate configuration that extends in a vertical direction along the side areas and in the back area. 
     
     
         5 . The article of apparel recited in  claim 1 , wherein the material is a warp knit textile. 
     
     
         6 . The article of apparel recited in  claim 1 , wherein a difference between the first air permeability and the second air permeability is at least 50 cm 3 /second per cm 2 . 
     
     
         7 . The article of apparel recited in  claim 1 , wherein a difference between the first air permeability and the second air permeability is at least 100 cm 3 /second per cm 2 . 
     
     
         8 . The article of apparel recited in  claim 1 , wherein the material has an elongate configuration that extends in a vertical direction along the side areas. 
     
     
         9 . The article of apparel recited in  claim 1 , wherein an area of the material in each of the side areas is at least 77 cm 2 . 
     
     
         10 . The article of apparel recited in  claim 1 , wherein an area of the material in each of the side areas is at least 232 cm 2 . 
     
     
         11 . An article of apparel comprising a torso region with a front area, a back area, and a pair of side areas, each of the side areas being formed from at least:
 a first textile incorporating a yarn that exhibits a dimensional transformation upon exposure to water, the first textile having:
 a first air permeability when unexposed to the water, the first air permeability being less than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737, and 
 a second air permeability when exposed to the water, the second air permeability being greater than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737; and 
   a second textile incorporating a yarn that is substantially dimensionally-stable upon exposure to water,   
       the first textile and the second textile being joined to each other in each of the side areas. 
     
     
         12 . The article of apparel recited in  claim 11 , wherein the apparel is a shirt and includes a pair of arm regions extending from the torso region. 
     
     
         13 . The article of apparel recited in  claim 11 , wherein at least a portion of the back area is formed from the first textile. 
     
     
         14 . The article of apparel recited in  claim 13 , wherein elements of the first textile have elongate configurations that extend in a vertical direction along the side areas and in the back area. 
     
     
         15 . The article of apparel recited in  claim 11 , wherein the first textile is a warp knit textile. 
     
     
         16 . The article of apparel recited in  claim 11 , wherein a difference between the first air permeability and the second air permeability is at least 50 cm 3 /second per cm 2 . 
     
     
         17 . The article of apparel recited in  claim 11 , wherein a difference between the first air permeability and the second air permeability is at least 100 cm 3 /second per cm 2 . 
     
     
         18 . The article of apparel recited in  claim 11 , wherein elements of the first textile have elongate configurations that extend in a vertical direction along the side areas. 
     
     
         19 . The article of apparel recited in  claim 11 , wherein an area of the first textile in each of the side areas is at least 77 cm 2 . 
     
     
         20 . The article of apparel recited in  claim 11 , wherein an area of the first textile in each of the side areas is at least 232 cm 2 . 
     
     
         21 . An article of apparel comprising a torso region having a front area, a back area located opposite the front area, and a pair of side areas that define arm openings, and the torso region having a neck opening and an opposite waist opening, the torso region being formed from at least a first textile and a second textile, the first textile forming:
 a pair of side elements that are located in the side areas and extend through at least fifty percent of a distance between the arm openings and the waist opening; and   a back element that is centrally-located in the back area and extends through at least fifty percent of a distance between the neck opening and the waist opening,   
       the first textile incorporating a yarn that exhibits a dimensional transformation upon exposure to water, the first textile having:
 a first air permeability when unexposed to the water, the first air permeability being less than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737; and 
 a second air permeability when exposed to the water, the second air permeability being greater than 279 cm 3 /second per cm 2  measured in accordance with ASTM D 737. 
 
     
     
         22 . The article of apparel recited in  claim 21 , wherein the apparel is a shirt and includes a pair of arm regions extending from the arm openings of the torso region. 
     
     
         23 . The article of apparel recited in  claim 21 , wherein the first textile is a warp knit textile. 
     
     
         24 . The article of apparel recited in  claim 21 , wherein a difference between the first air permeability and the second air permeability is at least 50 cm 3 /second per cm 2 .
