  • “Hi. I just received my hydration attachment. I wanted to let you know how impressed I am by the quality of your products. It looks great, it’s well built. The value is outstanding. I bought a Box vest right in the very early months of covid in March of 2020 and it’s by far the most useful and life-improving fitness gear I have. I’m really proud of carrying my vest. I wish you the best. You deserve that success.”  Thanks again.  Jean –  Customer for life
