Magna Magnesium Powered Hydration
Great taste, doesn’t bother stomach and gives you the right amount of calories, carbs and sodium needed for a long run.

The gels themselves are great, but when they arrived a few had opened up and leaked over the others.
Update: the folks at The Fooster reached out super quick and sent replacement gels! Thanks guys!

Got these for my fiance for an upcoming race and his words were “These are money!” He loved how clear they were and perfect shade when the sun hit them.
