Our line of Deluxe Inflatable PFDs combine the sophisticated security of inflatable innovation with product improvements such as comfort-improvement features and security inspection window to quickly inform users if the inflator is all set to utilize. The Velcro closure makes it easy to wear and preserve while near the outside to reduce chafing around the neck and chest; the neoprene Comfort Collar gets rid of neck inflammation. Made for leisure lovers and professional alike, the MD 3087 sports an automatic inflation system and is lightweight and close-fitting to ensure it does not conflict with everyday activities Automatic-activated inflatable PFDs inflate when they are immersed in water. They run on a little tablet that dissolves in the water and causes the inflator to trigger and fill the inflatable cell. They are an ideal choice for scenarios where you don't anticipate to go in the water-such as cruising or power boating - but desire the self-confidence that if the unexpected occurs, the PFD will inflate within seconds of remaining in the water to keep you afloat.
