I thought it might help people trying to get an idea of relative bag sizes if I posted a photo of four of my "family." (I also have an Indigo Tri-Star and two Brain Cells which didn't make it into this particular group shot.)
From left they are a 1st generation Ristretto in Olive/Cayenne (cordura); an ID in Plum/Black (ballistic); my brand new Imago in gorgeous Indigo/Plum (cordura); and my beloved 1st generation Swift (the kind without the black stand-up bottom) in an unbelievably beautiful ballistic Indigo. In case you couldn't figure it out, I am in love with Indigo.
Hope this helps someone make up their mind which Tom Bihn bag is right for them.
