700+ lb mesh suspended from all posts with 36" of rodent guard base. The mesh from a distance blends in well; posts are the most visible part of an enclosure. This picture is taken from next to the fence line extending towards the buildings about 100'.
600+ lb mesh suspended by extended posts designed for cat containment. Picture courtesy of our good customer Paul H. from GA. For cat containment applications, post usage is necessary because if you use trees to suspend your fence, cats will climb them to get out.
700+ lb mesh shown suspended from trees. Without posts, the fence mesh is nearly invisible. This picture is from 10' away. Surveying tape is hung at waist height to prevent deer from accidentally going into the fence line.
Poly mesh fencing is flexible and wont harm trees as they grow out. Deer like to eat skunk cabbage, especially as the plants first grow in the Spring and when the leaves are full in the Summer.

Deer fence using both posts and trees for suspension seen here blending in well with the tree line. If you look closely you can see the white surveying flags and the fence they're hung on.
