Just look at how much gear this thing holds. I have eleven 3700 sized boxes in there. ELEVEN. That's just the main compartment. The outside pockets are 3600 sized and there's so many little pockets that I just found another one today.
I had been using 2 Rubbermaid totes to house everything you see in the pictures, but it all fits easily in the XL tackle duffle. Construction is bomber. The foam dividers do a good job of helping the bag keep its shape when partially unloaded.
Now some drawbacks:
1. It's F'ing HEAVY when full. Seventy pounds more or less. Totally manageable for short trips over solid ground, but not something I'll portage. But, duh -- this is the mother ship tackle box.
2. All those little compartments can be confusing. It's easy to lose things inside the bag simply because I can't remember what side pocket it's in. I have smaller day boxes in the outside pockets and over half the time I end up with all of them open when I'm looking for one.
I love this bag.
