Picked up a vintage bag from the late 90s on eBay and it arrived today. Hard to find any info on the Super Musette, but got this from Wayback Machine archive of April 1999:
A bike messenger-style shoulder bag with class. Because of its complete lining and rigid foam stiffener, the Super Musette keeps its crisp looks and won't become a big sloshy mess on your hip. It has multiple pockets for pens, diskettes, etc. , plus both an open-top and a zip-top file-size pocket on the front under the big main flap. The flap has a super bright ReflexiteŽ stripe and secures with two big buckles; it has a zippered mesh pocket on the underside. Inside, the Super Musette is pretty simple - one big main compartment with snaps for the optional Lap Dog, making for a cool computer bag. The whole thing carries on a stout 2" webbing shoulder strap which ajusts on both sides with cam buckles and has a grippy pad, plus an adjustable and removable waist strap for bicycling. There's a simple 1" webbing grab loop on the back, too. Made of 1000 denier CorduraŽ with #9 & #10 YKK Coil zippers. Available in black / lime green, black / plum, and solid black. Come on you squares, get some color!
One size: 17" x 12" x 7" 1350 cu.in. / 22 liters $105
On the rear, there is a vertical loop of 1.5" webbing below the grab loop. Anyone have a guess about it's intended function?
