I saw these bags at Walmart while I was doing some last minute shopping for the trip to Alamogordo NM. American Tourister bi-fold tote. Measures 10"x17"x7". Hrmm, that might just fit in the bags on the Concours. $24.96ea
Sitting next to the helmet for a size reference.
---Ok, the test. Stuff in 3 t-shirts, 1pr Jeans, 1pr shorts, Swim Trunks, 2pr Socks, Toiletries and bottle of Gold Bond Powder. The bag splits open nicely for easy loading/unloading.
---The two main compartments are closed with a mesh panel on one side and a translucent panel on the other. I even fit my Teva sandles between the two main compartments and zipped the bag up.
---There is a side pocket for stowing the shoulder strap and some magazines. The other side pocket is perfect for organizing a bunch of smaller items (toothpaste/brush, deoderant, phone/charger, asprin, Pen/Pencil, Palm Pilot).
It fits! there's a little room behind it in that moulded area of the bag for a light jacket, and some bungies.
