Product overview

Built for the round.

A ready-to-drink sports performance beverage made for golfers. easy9 is positioned as an alternative to beer, soda, and generic sports drinks in the cart or clubhouse — supporting sustained focus and hydration over a ~4-hour round, not a pre-workout spike.

  • Consumed before or during an 18-hole round, walking or riding.
  • Moderate, sustained physical exertion over several hours, often in heat and sun.
  • Steady energy and focus — not jitteriness that affects your game.

My story

Built by a golfer, for golfers.

Easy9 founder Charlie with a playing partner on the course

I've always loved golf. Somewhere along the way I heard the advice everyone hears — do what you love — so I decided to build something in it.

I'm also a long-distance runner, and if you run distance, hydration isn't optional. It's the difference between finishing strong and falling apart. I brought that mindset to the course and realized golf deserved it too — a round is 4+ hours outside, often in heat, and the cart still rolls up with beer and sugar. Nothing built to actually help you play.

That's why I started easy9 — a drink made for the round you're actually playing. Real hydration, a clean lift of caffeine, nothing that works against your game.

The formula

Dialed in, not dialed up.

(a)70 mg

Caffeine

Enough to sharpen, never enough to spike you on the back nine.

(b)5 ion

Electrolytes

Sodium, potassium, magnesium and more to keep your legs steady in the heat.

(c)100 mg

L-theanine

Smooths the caffeine into a calm, competitive edge — no jitters.

Steady focus

Calm alertness, hole after hole.

70 mg of caffeine is about a small cup of coffee — just enough to sharpen reaction time and decision-making without the jitters that throw off a putt or a tee shot. 100 mg of L-theanine smooths the caffeine curve, keeping energy level steady instead of spiky.

  • No spike, no crash. The L-theanine helps prevent the sudden rise and fall you get from stronger energy drinks or pre-workouts.
  • Made for precision. Calm focus supports reading greens, club selection and tempo — not just raw energy.
  • Built for four hours. Sipped across a round, the modest dose sustains attention from the first tee to the 18th green.

Per 12 oz can

Why replace electrolytes? Four hours of walking and swinging in the sun means steady sweat loss — and sweat takes sodium, potassium and magnesium with it. Replacing them keeps muscles firing, prevents cramps and fatigue late in the round, and helps you hold focus when the match is decided on the closing holes.

12 oz can, fits a standard cart cupholder. Served cold at the pro shop or packed in the cooler.

The Taste

Cucumber-lime. Crisp from tee to green.

Cool cucumber opens the sip; bright lime cuts through the heat. Light, clean, and never too sweet — built for four hours in the sun.

  • Cool, refreshing cucumber finish
  • Zesty lime with a subtle tart edge
  • Light sweetness that stays drinkable all round
