Can the Snugli be submerged?

I have a snugli (baby backpack) and i was just wondering if it could be submerged in water with a child in it. I want to take my son swimming, and he loves to splash. I dont want to put him into a baby ring...he would try so hard to reach the water he would fall over. I wouldnt be but arms length away from him, but things happen. I was just wondering....
