We really like these cargo nets for both Wald 137 and 139 baskets. The Delta Cargo Net is affordable, durable, easy to use, and has nice plastic hooks so they don't poke into your expensive gore-tex and down jackets. If you've ever punctured a jacket you know exactly what we're talkin' about! If not... Well, that's awesome actually.
We actually recommend keeping one of these inside your Swift Industries Sugarloaf or Motherloaf too, 'cause if you ever run out of space you can strap stuff to the outside of your bag with this. Jeremy keeps his in his Rando Pocket on the outside of his basket for safe keeping!
