I fly into SD for my trips. I need a couple decent checked bag size rolling duffels preferably at least water resistant. Calcutta has an ideal bag, and the backpack duffel looked good too, but now they're sold out. So, what do you guys who fly in for your trips use? Since it's just me toting my gear around, and going home might include a fish box, rolling is ideal. Collapsible so they will fit in my stateroom. Can't seem to find anything quite like the Calcuttas.
