Most deerblock mesh I've tried goes bad after a year, but this mesh has really stood up well here in the sunny south. No problem at all with it falling apart due to UV and exposure to the elements. I created a totally enclosed area that is 20' x 32' by 8' high for growing vegetables during all 4 seasons. The mesh is still like new after more than a year in place, and no animals have broken through it. It has even stood up to small limbs falling on it.
