  1. Best Cold Weather do anything outside layer


    Using this all the time for all things outdoor, fishing, skiing, winter biking... My daughter named it my fishskibike shirt! Love it so much I'm ordering 2 more for future use.
  2. Great product


    Just bought this from ted fay flyshop in dunsmuir ca this is the best product out there. The only thing I would change is the product name and size placement. Tag is very uncomfortable causing itching at the back of the neck had to remove tag.
  3. Game Changer Piece of Layering


    This is a must have. The style is based on the solarflex long sleeve shirt design including a neck gaiter and hood but only this is for cold weather. Brilliant. I used it all fall in cold weather under my rain gear, layered under other gear and it kept my neck totally covered including in Northern Minnesota duck hunting wind and snow. Unbelievable. Can't wait to use this for winter steelhead fishing. There is no other product of this design. I will use this for outdoor training as well. Nicely done Simms!
