I did check these goggles out in a warm shower, so I know that they are leak proof and fit very well. I do feel that they are of high quality and they do come with a case, and can fit in your pouch or small pocket in your swimming tote. Plus, the makers of this product have a 12 Month money back guarantee, which to me speaks volumes, as they know they stand behind and awesome product. As soon as winter is over, I will be hitting the pool to workout and do some swimming, as I feel that is the best way for me to work out with the least resistance on my body.
