The 4 pack of Caravan Premium Canopy Weight Bags is a must have for Vendors that participates in Framer's Markets and Out Door Festivals. Each bag has two pockets that can be filled. I filled both side of the pockets with "regular sand". Each bag held up to 25 pounds of sand. Therefore 100 pounds of sand will easily fill 4 sand bags - both sides of the pockets. If possible, have someone help you fill the bags. It is rather a challenge to pour sand from the bag and hold it open/up-right. Using a garden scoop to fill the bags takes forever. More and more Framer Markets seem to have a mandatory 20 pound requirement for each leg. Having 25 pounds each leg is perfect just in case of the unexpected windy day/Rain storm. The price is the best I could find for this size. Sand to fill if from the hardware store was only about six dollars for 100 pounds. Since the top just folds over and velco to itself, sand will leak out in transport. If this concerns you - just use a thick mil bag in side the canopy bag. The Canopy bags have heavy duty handles sewn to each bag. When picked up it looks like a "hand-bag" and the weight is distributed well for moving and carry. Well known and proven brand for out door equipment as well.

This bag is hard to fill with sand by one person and it is hard to handle after putting 25lbs of sand in it. They do the job in keeping the canopy weighted down, just too hard to handle.

No instructions came with product and it was over priced for what it does.
