@Claire This one has worked well for me for over a year… walking, jogging, hiking, and even with regular pants and my shirt tucked in. It’s still just a good as the first time I wore it. The price is right and has a 4.5 of 5.0 rating from almost 8,000 buyers. Make sure you watch the video presentation.
