I'd love to have a Clear Quarter Cube in Iberian, with one additional choice: make at least one urethane panel in the Clear Quarter out of the packing cube mesh, not the urethane. Eagle Creek makes a versatile bag like this, but it's larger than the end pockets of an Aeronaut, weighs more, and isn't made in the US. A double-sided mesh Quarter bag would be great, as well!
I travel with an insulin case which needs access to air or it doesn't work. It's just the right size to fit into the Clear Quarter, but the solid non-breathable sides keep it from working. I've been puttiing it into a Small Aeronaut mesh cube, but it leaves a lot of wasted space. I can't pack clean clothes right up next to it in the same cube or they get damp.
I can't be the only person out there who'd like this. I think it would be useful for a bathing suit or men's trunks, wet travel towels, damp socks, or anything else you'd want to air out instead of being closed up to mildew. It would also make a great dry toiletries kit to go with the 3D or Kit. I have a habit of packing everything as soon as I can (so it doesn't get left behind), but right now I'm using my old Eagle Creek small cubes for wet items instead of putting them into the larger Aeronaut small cube. That one's usually full of clean undies or shirts. I hate using it for my Frio! I'd love to retire the EC stuff, they're old (25 years) and getting tatty. I could buy more, but I'd just rather buy US made Tom Bihn if I can.
Ah, even a 3D in mesh would be nice. It would weigh more 'cause it's not Dyneema, but I'd still buy one.
Iberian for the Cube, of course, but I think there'd be a demand for Solar, too... hint beg grovel.... whine, even
