Great covers.  Wish they had the feature listed in the discription.  

Does not have the "Strap & buckle systems are included to help better secure the cover to your furniture in windy conditions."  Nor the "Sewn-in vents are strategically placed throughout the cover to ensure adequate airflow to release any trapped condensation, preventing the build-up of mold, mildew & rust."  Have already had one cover lifted up from the chair during a windy day.

Otherwise great chair covers.
