Has anyone seen one of these before?

"With four sides, a top and bottom - RuffSack secures and protects your cargo from the elements without permanently filling your truck bed."

 

No, but for short term storage or traveling with bad weather, I'd give it a shot.

 

Save your money! I bought a RuffSack to keep things dry in the bed of my pickup on a road trip. I am sorry to say, it didn't last one day. The seam holding the bag together in the left rear corner first ripped a hole in the bag, and then proceeded to completely come apart, leaving the entire corner to flap around. Needless to say, things did not stay dry during this trip. In fact, as I was putting the RuffSack into the bed of the truck, I couldn't help but notice the grommet in the upper right rear corner had not even been installed. There wasn't even a hole for one. To use the bag, I had to use a tarp clamp to secure the corner.. All in all, a pretty shoddy piece of workmanship.
