A disposable surgical gown is provided. The gown includes a front panel and sleeves formed from a first spunbond layer, a nonwoven (e.g., SMS) laminate, and a liquid impervious, moisture vapor breathable elastic film disposed therebetween. The gown also includes a first and second rear panels formed from a nonwoven laminate that is air breathable and allows for an air volumetric flow rate ranging from about 20 standard cubic feet per minute (scfm) to about 80 scfm. The gown further includes a collar formed from an air breathable knit material positioned adjacent a proximal end of the gown. The collar defines a neck opening having a v-neck shape adjacent the front panel. The v-neck shape forms an angle of greater than 90° at the neck opening. The combination of features results in a reduced-glare gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.

The disposable surgical gown of any of the preceding claims, wherein the elastic film has a basis weight ranging from about 5 gsm to about 50 gsm.
The disposable surgical gown of any one of the preceding claims, wherein the outer spunbond layer and the SMS laminate include a semi-crystalline polyolefin.
The disposable surgical gown of any one of the preceding claims, wherein the outer spunbond layer has a basis weight ranging from about 5 gsm to about 50 gsm and the SMS laminate has a basis weight ranging from about 10 gsm to about 60 gsm.
The disposable surgical gown of any one of the preceding claims, wherein the outer spunbond layer and the SMS laminate each include a slip additive.
The disposable surgical gown of any one of the preceding claims, wherein the first rear panel and the second rear panel each comprise a SMS laminate.

The disposable surgical gown of any one of the preceding claims, wherein the disposable surgical gown exhibits an opacity of greater than about 98%.
The disposable surgical gown of any one of the preceding claims, wherein the disposable surgical gown exhibits a light transmittance of less than about 0.1.
A laminate material comprising a liquid impervious, moisture vapor breathable elastic film positioned between a first material and a second material, wherein the first material comprises a nonwoven layer and the second material comprises a spunbond-meltblown-spunbond laminate, wherein the elastic film, first material, and second material each include a carbon black pigment and titanium dioxide, wherein the elastic film further includes a fluorochemical additive, wherein the first material and the second material further include a slip additive, and wherein the laminate material exhibits an opacity of greater than about 98% and a light transmittance of less than about 0.1.
