    I Sail on San Francisco Bay which can be very cold. This kept me warm all day. It is lightweight and allows me to move about easily. I highly recommend and we’ll be getting the pants also.

    Wow! It really is different. I am bald and once I shaved my head I had to wear a ski hat in the house during the winter. Not anymore. You literally feel a difference within minutes of putting it on. Tried it on the ski slopes. I usually wear 3 layers plus my heavy ski jacket even if 50 degrees out. It was 50 degrees and I just had a light silk undershirt plus this (people think it looks cool by the way) and was completely warm. So thrilled about the technology, I bought the mittens. Excited that my harsh winter ski trips will be much more comfortable. Folks, it really works. Note, the sizes run small. Had to return my normal size of small to get a medium. The medium is tight but works. Telling all my ski buddies about it.

    Wanted this as soon as I saw it on Shark Tank. It delivers just as shown on show. Comfortable, great for early season golf, fits great. It oes run a tad small so go up one size. Could not be happier with this product. Gtting one for my father in law. And another one for me.
