Love Skratch hydration mix. Been using it for several years now. Really like this larger size if for no other reason than making it easier to scoop. I found the smaller bags harder to use and always transferred the powder into a container. Not necessary with this new size.
Scratch was rated 1 hydration powder by Velo- Qubec in 2017. I like its taste, not too sweet and that it's not sticky. On top of it, it is natural, made with real fruits and non GMO
