Black Swiss backpack

I lost my backpack on the way home from IFSC yesterday, it looks like this: https://webobjects2.cdw.com/is/image/CDW/1021163?$product-main$ It's black and grey with the red Swiss logo, and also has a red bike light attached to the top handle. It's a work backpack, so it has a laptop and a kindle in it. Not sure exactly where I lost it, but it was likely either around Amiens st bus stop, or around Artane - Ardlea Rd/Hazelwood.
