I bought these gloves for my daughter's visit to New Hampshire.  It was her first time seeing snow.  She made her first snow man... her first snow angel... and went hiking, snow shoeing, snow mobiling, skiing, and lots of other winter sports....  all with these gloves.

She told me that her hands were never cold.

And... she has lived her whole life in Florida.

So... I would say that these gloves are warm enough... and waterproof-enough... for just about anyone.
