Instead of wearing a bulky personal flotation device under a snowmobile coat, one could wear a swimmer's belt? These are similar to the old water skier belts from the 1960's. Basically a bright yellow or white foam belt, about 5" high x 1 1/2" thick x 36" long, fastened with one strap with adjustable belt clip; designed for balancing your buoyancy and swimming and easy to adjust for best fit and swim movement. Cost; about 25-dollars locally at
www.parafunalia.com in Gilford.
For $25-belt and $10-hand spikes, you get some extra safety? And, the bright orange ice rescue spikes can be loosely tied to the buckle area of the swimmer's belt. A bright yellow belt with bright orange rescue spikes would certainly be colorful ... yellow and orange....and worn hidden away, underneath the winter coat.
For a 2017-made, retro-1920's style swimmers belt .... at a very reasonable price-$16.95 .... maybe try googling "Tyr aquatic flotation belt." The Tyr aquatic flotation belt is basically a design from a hundred years ago, similar to a sturdy cotton strap with attached oval shaped, natural cork floats....and remade with 2017-modern materials. Suggest you check out all the reviews on it, at the SwimOutlet.com .... is the colors black & blue.
Sometimes, you can find an old 1960's water-skier belt at a yard sale for like 50-cents .... such a deal!
Anyone want to volunteer crashing their snowmobile through the thin ice while going 20-mph to test the swimmer's belt for practical use ...... like duh!....what hit me?.....and, am I still alive?.....or, just in the panic and mentally painful process of drowning?.......gasp-gasp-gasp???
