Gu Roctane Bulk Pack
Love this stuff and it works for me in the heat really well. It is easy on the stomach and provides plenty energy. I love the pack and gu bottle routine. Really works well for me. Easy to get a shot of gu on the go.
The drawback is the price. Now that I know these work really well, I will probably reserve these for events are they are too pricey to use all the time.
