I love this bag. I keep it packed for races, so I always have everything I need ready to go. I have a Giro Xen helmet, and it fits in the bag (as shown above) with no problem whatsoever. My shoes fit next to it. I can fit two racing kits, tools, Gu's and other supplements, a giant container of Heed, two water bottles and my CamelBak, extra tubes, box of CO2 cartridges, and more. And the bag isn't full yet. It's the best bag if you need to have a way to keep ready for anything at anytime.
