    Expert Review

    The gel mix is rad! So cool to carry one flask with three gels & not have to jam sticky spent plastic wrappers back into my belt once I’ve taken a gel. The neutral flavor is great. And it’s super easy to mix especially when I remember to do it the night before.

    This product is for…

    Trail and ultra runners who want to reduce single-use gel wrapper waste and prefer to control carb density and consistency in a single flask. Also suits runners sensitive to GI issues or sweetness who benefit from a neutral, low-preservative formula.

    Worth noting…
