I have been a happy MD3183 owner since 2013 or before. The flexible fit was awesome whether I was wearing a Tee in 90 degree or a 100 mph suit in 30 degree weather. I ordered the new 190 as it didn't make sense to order a re-arm kit for a discontinued vest but gaining more buoyancy with the 190. However I was unhappy to find the new one has less flexibility fit than the old one and didn't even try it on with the 100 mph suit. I ordered the extension strap but needed very little of it to get the same flexibility I had. Suggestion: make the vest straps as long as th MD3183.

I have been using Mustang's Inflatable life vests for years . I use them while fishing in my waders and on my boats . They have always fit well and performed well . Recently I purchased the Fluid 2. 0 inflatable belt for my fishing waders and it doesn't fit . The belt is cut way to short it won't fit around the waist , let alone around a fishing wader or bibs and when layering. They don't make an extender belt for the inflatable waist belt . This will absolutely limits its use . The cost of giving the belt a few extra inches is minimal . Using different buckles that are not universal also limits its use . The newest designed inflatable vest are also cut small and at a cost of over $300 and still requires an extension belt , however they are also not universal buckles and don't fit the belt and cost an extra $20 dollars plus shipping . The waist belt give a chest measurement but no waist measurement where you wear that belt . Useless in sizing for a belt device. The vest inflatable fit with the proper extension belt , but just making it a few inches longer would have avoided the need for an extension belt . " Big problem" for big people . we all know that wearing a life vest can save lives , but only if they fit ! All extender belt should use the same universal buckle for all your devices .

Needed extender to fit flotation around survival vest. Works great in the hangar, hope I never have to test it in the wild.

This extender is allowed by USCG if the user's chest is larger than 52" and they are using a universally-sized vest...which I am.
