Airblaster Expedition Weight Ninja Suit
Here's what other sites are saying:
The Airblaster Expedition Weight Ninja Suit is quite possibly the warmest long underwear in existence anywhere on this planet. Maybe even other planets, too. Four-way-stretch microfleece and the seven-panel hood seal in warmth and make you all but impenetrable to the elements without restricting your mobility.
