Our line of Deluxe Inflatable PFDs combine the advanced safety of inflatable technology with product enhancements such as comfort-improvement features and safety inspection window to easily tell users if the inflator is ready to use. The Velcro closure makes it easy to wear and maintain while closing to the outside to reduce chafing around the neck and chest; the neoprene Comfort Collar eliminates neck irritation. The MD3082 sports a manual inflation system and is lightweight and close-fitting to ensure it doesn"t interfere with daily boating activities. Made with an integrated sailing harness for extra safety, the MD3082 is designed specifically for sailors frequenting rough weather. Manually-activated inflatable PFDs are inflated by pulling the inflation cord that hangs from the PFD at waist-height. They will not inflate when they get wet or are immersed in water. Manually-activated PFDs are a great choice for activities such as paddling, wade-fishing and swimming where there is a reasonable chance you will end up in the water and are confident you will be able to pull the inflation cord when you need it. They are also ideal for situations where control over PFD inflation is desired
