First time poster, occasional lurker. So I have trip planned to the Big Island of Hawaii with a group of coworkers. We will have an all day trip planned visiting various snorkeling spots. We also have a day of surfing planned. None of them know I am wearing and don't want anyone to find out this way. Would like to enjoy the experience and not worry about it. I use a skin based system. Does anyone have experience in this area, and what do you guys recommend? Does Walker work with a skin system? Tried Walker once, it shines too much and smells like airplane glue, and I hated it. Thanks for any input, much appreciated.
