I’m sure there’s a product you can buy that is this kit. In reality, it’s a simple tarp shelter. Look up some videos on how to make tarp shelters on YouTube, there’s lots of different ways and it’s good knowledge to have. Most of them you can make with paracord, a tarp, and something to tie off to like a tree. Of course on the beach, there’s nothing to tie off to, so you need the poles. Normally you could run your ridge line between two static objects.
