High quality material that is tightly woven and has a backing on it to seal the sand in BUT it's not designed for advertised purpose - sand/weight bags. The seams are not double sewn and the top does not seal. Instead it has a rope-pull design which leaves a gaping hole for the sand to fall out of. It doesn't even have a token flap to slow the escape. This means the ONLY way these bags can be used is upright, tied to a pole to keep them from toppling - as pictured) and if you're not going to remove the sand between uses, they have to be stored upright too. The only way I can see to salvage some use is to use a sturdy plastic bag to put the sand in & seal that one well. Then I can use this purchased disappointment both standing OR lying - as originally intended.
