Layering is the key to warmth when we Scuba dive. By layering we breathe slower, conserve our air supply allowing us to make longer and more enjoyable dives. Smart design pays big dividends in comfort with this multi thickness hood. The thinner, oversized bib is made to tuck easily into wetsuits forming additional layering for a good seal and an overall anatomical shape that helps eliminate sags & air pockets. The face seal can be trimmed to precisely match unique facial contours for custom fit, make longer and more comfortable dives. NeoSports 7/5mm vented bib hood has an integrated flow vent that allows bubbles to escape through the top of the hood preventing ballooning without promoting water exchange. All seams are glued & stitched for durability and to limit water exchange. The Hood body is made from 7mm nylon-2 neoprene with the bib being 5mm. Hood is black in color and is available in multiple sizes.
