Protekt Electrolytes Liquid Hydration Packets ($13)

I've tried my fair share of hydration packets through the years, but I'm particularly obsessed with the ones that actually taste good (I love anything lemonade flavored) that also include magnesium for muscle support. The best thing about Protekt is that it's liquid, which makes for a far better mixing process than powder in my experience. Protekt is also sugar-free.
