The line of deluxe manual inflatable PFDs combine the advanced safety of inflatable technology with new product enhancements such as a safety inspection window to easily tell users if the inflator is ready for use and a neoprene comfort collar to eliminate neck irritation. Made for sailors and power boaters alike, the MD3085 sports a manual inflation system (the user must pull an activation cord to inflate the PFD) and is lightweight and close-fitting to ensure it doesn't interfere with regular activities. It is USCG Approved Type V PFD for use when worn on uninspected commercial vessels less than 40 ft. in length not carrying passengers for hire as a substitute for a Type II or III PFD when used in accordance with the owner's manual. Use only Mustang Survival re-arm kits. Use of other re-arm kits may result in improper operation or failure to operate and will void the product's warranty.
