I bought the 14x17 and it is too small to be used on the trunk rack holding down a bag. The 40x50 would be to big for that purpose as someone else have commented. They really should have a 3rd size in between, maybe 27x34?

I'm sure I will find a use for it someday so I'm keeping it in my pannier.

Not sure how long it will last if exposed to the elements for long duration of times.

Still, 5 stars as there is nothing wrong with the product.

This is a great little bungie net. will work great on the smaller stuff of the bike

I got the small one. Very versatile, matches the shape of the Kuryaken rack well. Can't go wrong here.

awesome price and size works well for rack

Well, got one for me and one for my Buddie for a coming Yosemite trip we are going on May 18. This will hold my travel bag on the passenger seat which will become my back-rest.
I plan to install a trunk rack for the bag, but don't really like the looks of all that crap on the top of my trunk. How about you?
Buddie's bike has little saddle bag room so it will hold his crap bag on his passenger seat as well.
