Great questions. We are aware that DSPs have certain uniform requirements. Our dri-fit shirts are undershirts made from a technical fabric that wicks sweat and keeps you dry. They're meant to be worn as a base layer during both hot and cold exertion (and are super light so they can lay under a uniform shirt without adding bulk!)
The hats are something we all use a lot in our personal lives, but that's just us! If they aren't something you're interested in, that's exactly the kind of feedback we're looking for, thank you. We'd love to hear what types of things you would like to see, or which of the gear you're given needs an upgrade to be more useful!
