TECHNICAL FIELD 
     Embodiments described herein generally relate to a multi-layered glove and, more specifically, to a protective fire glove. 
     BACKGROUND 
     Firefighting presents many different types of hazards against which firefighters must be protected. Firefighters encounter extreme heat, direct contact with fire and flash-flames, blood-borne pathogens, chemicals, water, steam, and the like. Furthermore, gloves used by firefighters must protect against impacts, punctures, and cuts. 
     While many current firefighting gloves are compliant with National Fire Protection Association (NFPA) 1971-2018 Edition Standards, various features for these types of gloves remain deficient. As such, a need exists in the industry for an improved protective fire glove.

     Examples 
     An example back portion glove pouch and a comparative glove pouch were subjected to the NFPA 7.7.25 Transmitted and Stored Thermal Energy Test. The Transmitted and Stored Thermal Energy Test is used to evaluate, on average, how long it takes to experience a second-degree burn on the back of the hand caused by radiant heat. This test is performed in accordance with ASTM F2731 on the glove body composite back side under wet conditions. The test measures the heat transfer through the composite when it is exposed to a radiant heat source at a specific heat flux and relates the transferred heat energy to a predicted time of second degree burn injury. The time to second-degree burn are recorded for each specimen. According to NFPA standards, the time to second-degree burn cannot be less than 130 seconds. 
     The example back portion glove pouch included the following layers, moving from the exterior to the interior of the example back portion glove pouch: a layer constructed of 360 gsm yellow Kevlar® knit, a layer constructed of 240 gsm Nomex® knit, another layer constructed of 240 gsm Nomex® knit, a layer constructed of Porelle® FR, and two layers of 240 gsm Nomex® knit bonded to one another. The comparative glove pouch included the following layers, moving from the exterior to the interior of the comparative glove pouch: a layer constructed of 1.0 mm grain cow leather, a layer constructed of 240 gsm Kevlar® knit, a layer constructed of 240 gsm Nomex® knit, a layer constructed of Porelle® moisture barrier, a layer constructed of 240 gsm Nomex® knit, and another layer constructed of 240 gsm Nomex® knit. 
     Tables 1 and 2 below show the stored thermal energy results for specimens of the example back portion glove pouch and for specimens of the comparative glove pouch, respectively. The average time to second degree burn for the specimens of the example back portion glove pouch was 264.4 seconds. The average time to second degree burn for the specimens of the comparative glove pouch was 151.0 seconds. As demonstrated from the test results, the example back portion glove pouch, constructed in accordance with embodiments described herein, not only meets NFPA standards, but performed significantly better than the comparative glove pouch.
