Whether the definition is technically or legally correct, I would agree with the original poster that it's marketed as being waterproof. I would say they're trying *really* hard to convince you they're waterproof while not *technically* saying it.

1. The sentence "Keep them comfortable and happy with these warm, weatherproof, synthetic leather gloves." is pretty much designed to make the casual, non-experienced reader think it's waterproof. Seriously, if I told you I thought the glove was waterproof and you read that, don't you think that 50% of the time you might scan over "weatherproof" and think it was "waterproof"? I don't think it's a coincidence that the 2 words "just happen" to be so similar in appearance.

2. The next sentence is "Made with AmFIB®-Block, 35% polyurethane, 20% polyester, 28% nylon and 17% Airprene®, for good water and wind protection." I'm sure they chose the AmFIB word to sound like it's designed to deal with water. "good water...protection" again implies that it's waterproof.

The whole marketing speal is designed to heavily imply that it's waterproof, so I would say it definitely counts.
