Truck bed storage
Size: 59 inches
Great net, perfect storage space. Sticky mounts are useless! Be prepared to buy some heavy duty double sided outside tape to keep them in place but outside of that 0 complaints,

Best Bang for your Buck
Size: 59 inches, Size: 59 inches
Bought this almost a year ago for my 2018 silveraldo 1500 and it's very handy for big groceries shopping like Costco. I have a mat at the bottom just in case there's some kind of liquid and I dont want my groceries touching it.
Easy install, store a good amount of stuff, and pretty sturdy

I'd buy it again
Size: 59 inches
My pickup is often a grocery getter for me and the horses. I'm short. If stuff slides to the front of the bed it's a pain to get out. This is not a real heavy duty net but it works terrific for me. I was satisfied with the value for price and it's made my life easier!
