The sand pockets are just the pockets on the insides of the corners that you fill with sand for added stability. You use the sand in the area around you if you have it. There are guy ropes to tie it down though as well.

We put sand in Ziploc bags and placed them in each corner pocket. It allowed for more weight at the bottom. The shelter does come with stakes and a string that attaches around the bottom for more support. With stakes, I feel like it would work great. We used it at the beach and could not stake it into the soft ground.
