A closure for use on protective garments is defined by two oppositely-facing, longitudinally-extending edges of fabric having an opening therebetween as a slide fastener spanning the opening. A longitudinal channel is provided adjacent the fastener and formed by layers of the fabric for collecting and discharging materials out an opening and into an optional receptacle. The channel is formed by folding an outer front panel of the garment back onto itself. The zipper is then stitched to the interior end portion and a patch along a first stitch line. The patch is folded back on itself and the opposite end of the patch is stitched to the outer front panel of the garment along a second stitch line. Seal tape is placed over the second stitch line, thereby forming a sealed channel between the outer layer of the garment and the patch layer between the first stitch line and the second stitch line. Any gases, vapors and liquids that might otherwise penetrate the stitch lines are passed into the channel, and drained away from the user. A flap may also be added over the front of the closure to cover a portion of the fastener and the channel and provide an additional layer of protection.
