Sweat runs fast on hot sand, and plain water only takes you so far. CoastalHydrate replaces what an afternoon of open-court rallies pulls out of you — sodium, potassium, magnesium and chloride — with a light tropical-citrus taste that goes down easy on the changeover.

Why we stock it

We kept losing the third set to leg cramps, not to better players. CoastalHydrate is the mix that finally fixed the fade — enough sodium to matter, light enough to drink all afternoon, and it actually tastes like something you want in the sun.

“Three matches deep in July heat and my calves finally quit cramping mid-rally. Tastes like a beach bar, not a chalky gym powder.”

“Half a scoop in my bottle carries me through a two-hour session with no 3pm crash. No weird aftertaste, which is rare.”

Devon Pryce · Weekend hitter Verified buyer

“Does exactly what I need on hot mornings. Only knock — our foursome burns through a tub fast, so bring on a bigger size.”

FAQ

Questions from the sand.

How many servings, and how do I dose it?

Each tub is 30 servings. Stir one 7 g scoop into 12–16 oz of cold water about 20 minutes before you warm up, then sip through the match. On the hottest days a second scoop mid-session is fine.

How long does shipping take?

We ship from our Florida facility within one business day. Standard delivery is 3–5 business days in the continental US, free on every order over $75.

How should I store it?

Keep the tub sealed in a cool, dry spot and use the included scoop dry — clumping is just moisture getting in. It stays fresh well past a hard summer of daily use.

What's your return policy?

Give it a few sessions. If the taste or feel isn't for you, send it back within 30 days for a full refund — even if the tub is opened.
