I have a crush on my Airblaster Women's Ninja Suit. I have been snowboarding for a long time and base layers were always a second thought until I purchased my Airblaster Ninja Suit. Once you go Ninja you will never go back. It is the best thing ever! There are no gaps between top and bottom to let cold air in and the uni-suit design protects you from the infamous ice burn on a bad fall. The waistband zipper allows for ease of a bathroom break whether you are up in the woods or down in the lodge. I wear my Ninja Suit riding, camping, around the house, and anywhere I darn well please when there is a chill in the air. I have the biggest crush on this thing. I heart you Ninja Suit!
