I used the Gladiator Cargo Net today and it works perfect. My review:
If used properly, the Gladiator Cargo Net gives you the comfort that the stuff in the back of your truck will stay in the back of your truck.
The heavier construction and breathability of the cargo net ensures that that does not flap like thinner, solid tarps often do.
The 4 included cinch straps & hooks and abundance of tie down grommets make it easy to secure the cargo net to the truck bed.
