I like the looks too and it works great as long as you are solo.
I just packed it for a 3 day trip to Idaho tomorrow and I'm impressed. It holds:
2 pr. shorts
1 T shirt
1 pr. sandals
2 pr. sox + 2 underwear
sm. toiletries bag
my mac book air + a small bag of misc electronics- mouse, chargers etc
the 2 small outside pockets hold my light weight leather gloves and my mesh gloves with room in the large pocket for my winter gloves
All of this without expanding the top. With the expansion I can fit my jacket and pants liner.
Under the seat is my rain gear, covers for seat and bag, cpap machine and a down pillow which I insist on having.
