Rivendell's coveted BLUE CAPTAIN HOOK net. Made for them to their specific dimensions that fit perfectly with a 137 or 139 Wald basket. It's made out of heavy duty elastic which keeps it from turning into a pile of non-stretchy rope like some of the cheaper nets out there. Finally, the HOOKS! They're big, and beautiful, and hooky, so you know they'll keep your net nice and secure.
Here's a tid-bit of a tip from Riv and a good example of why we love Riv:
Tip-tip: They come with four hooks. Remove two, tie those two corners onto the basket, and then replace two small hooks from another net with the two you just took off. Then you’ll have two spare smallish hooks, and those’ll get you nowhere, but keep them around anyway.

Put it on your basket so your stuff doesn't fly out.
