How do the HayPlay bags work in sandy conditions?Updated a year ago

The HayPlay Zip bags would probably be best in sandy conditions since the back of them are solid. Sand might still get in the holes on the top of the bag if they are pawing at it or kicking sand into it, but in general, it is going to keep it to a minimum because of the solid, enclosed material. The HayPlay Tie bags that roll would also help to keep sand out but since they are rolling around there is the likelihood of more sand getting in them. However, there are also holes for the sand to fall out of in these bags too.
