Tom reveals more about the Western Flyer

"The Western Flyer is a small carry-on bag similar to the Aeronaut in function. It's volume is about 25 liters or a little more than half the Aeronaut's volume.

Rather than convert to a backpack as the Aeronaut does, it has a sling-bag strap, like the Buzz. This strap is designed to be worn cross-body on the right shoulder; it zips away when not in use. A Poron padded handle and two heavy metal "D" rings (for an optional shoulder strap) allow you to carry it the conventional ways too.

The Western Flyer has three exterior pockets (two zip closed) and two equal-sized main compartments (like the Brain Bag). The front compartment can be further divided in two with a zip-out divider, creating two compartments well sized for shoes. The back compartment has webbing loops so you can use annex clips to secure a Brain Cell (horizontal or vertical; we'll let you know soon which sizes fit, not all for sure). Matching packing cubes will follow shortly.

The Western Flyer is made of 1050 ballistic nylon in crimson, steel or black; lined with Dyneema/nylon ripstop. Ships late December or early January, we hope! [Available for pre-order before then]" -- posted by Tom Bihn in the Forums
