Use this primarily in the Winter when I often have two to three sets of cycling clothes and a helmet in my vehicle so I can ride either road or mountain depending on weather.  I can fit two pair riding shoes, long cycling tights, leg warmers, two pair cycling shorts, two cycling jerseys, leg warmers, arm warmers, wind break shell, glove liners, light gloves, heavy gloves, cap, long sleeve jersey, towel, and energy bars in this bag.

As previously noted, would be nice to have double zippers on all enclosures.  The internal bag to isolate dirty/wet gear from the main compartment is userful.  Bag is large enough that when full you'll want to use the shoulder strap.

Construction and materials, like other OGIO bags I've used, is very good.  Somewhat difficult to find what you're looking for when bag is full, would be nice if it had a some internal netting for organizing smaller objects though the external compartments are good for wallet, phone, energy bars, toiletries etc.

Overall am pleased with bag, would give it 5 stars if it had double zippers, internal nettting.
