Most are online now with measurements. I caved and ordered the lunchbox. Size seems similar to my Willis 18's with a tiny bit more depth. I just hope it's not too similar to my Riley 18 in color. The smaller saddle seems like a good size too, but strap isn't adjustable. I had to back a few items out of my cart because I don't want to have to knot my strap to length. I prefer it to be adjustable or detachable.
Edit: looking at
Nordstrom pictures the strap may be adjustable.
Coach description does not mention it is. Always a mystery.
2nd edit:
Nordstrom lists the lunchbox as 6 x 6 x 4 and Coach has 7 x 6.25 x 4.25. More mystery and that 1" is a huge difference.
