Buoy vs Liquid I.V.: The Backpack at Gate 23

The receipt showed $29.99 for a 30-serving tub of BUOY, a number Maya circled twice in blue ink at 6:14 a.m.

At Denver International Airport, she shoved the receipt underneath her passport while watching Gate B37 flash DELAYED.

“Take the hydration packets,” her expedition leader had texted at 5:52, followed by one terrifying sentence: “The ridge is hotter than forecast.”

Three summers earlier, Maya had learned what dehydration felt like while climbing the Angels Landing trail in Zion, where her water bottle felt heavier than her camera.

Her backpack now contained one stainless-steel 24-ounce Hydro Flask, three Liquid I.V. sticks, and a small pouch of BUOY.

A BUOY serving is designed as a concentrated electrolyte-and-trace-mineral liquid rather than the powdered stick format Maya was accustomed to.

The airport coffee kiosk charged $6.25 for a large cold brew, making her $1.00-ish hydration calculation feel suddenly ridiculous.

“Why are you comparing electrolyte brands at six in the morning?” her coworker Daniel asked from the charging station beside Gate B39.

Maya pointed toward the Liquid I.V. packet and said, “Because tomorrow I’m hiking above 10,000 feet.”

Her phone displayed the trail forecast: 32°F at dawn, 68°F by noon, 18 mph wind.

The memory returned: a cracked plastic bottle, a dry mouth, and Maya sitting beside a red sandstone wall outside Moab, Utah, wondering why she had ignored hydration until she felt awful.

Liquid I.V. Hydration Multiplier traditionally combines electrolytes with ingredients including sodium, potassium, and sugar designed around its hydration formula.

BUOY takes a different route, using a liquid concentrate that Maya could measure directly into her water bottle.

Her spreadsheet labeled “TRIP COSTS” showed $184 for lodging, $73 for transportation, $61 for food, and $29.99 for BUOY.

Daniel’s Slack message arrived at 7:02 a.m.: “Choose the one you’ll actually remember to use.”

Maya remembered the orange Liquid I.V. packet exploding inside her backpack during a 2019 road trip through Nevada.

A tiny stain still decorated the corner of her old Nikon D5600 camera bag.

BUOY’s bottle occupied more vertical space than a single powdered stick, a tiny logistical disadvantage inside a backpack already carrying crampons.

Liquid I.V., meanwhile, could disappear into the smallest zipper compartment beside Maya’s USB-C power bank.

At 7:41 a.m., the airport announcement finally called passengers for Denver-to-Salt Lake City Flight 2187.

Maya opened her notes and wrote one sentence: “BUOY is convenient for customizing water; Liquid I.V. is convenient for carrying individual servings.”

The airplane climbed through 12,000 feet, and Maya watched Colorado shrink beneath the wing.

Her water bottle contained BUOY, measured according to the label, while the Liquid I.V. packets remained unopened in her backpack.

At lunch, the guide announced tomorrow’s route would cover 8.7 miles with 2,900 feet of elevation gain.

Maya looked at the two brands again, suddenly realizing the comparison was never really about which logo looked better.

It was about whether she preferred a liquid concentrate she could dose into her bottle or individually packaged powder she could grab without measuring.

The canyon trail began at 5:46 a.m. the next morning.

By mile four, Maya’s backpack felt heavier, the sun felt closer, and Daniel finally asked which one had survived the experiment.

She pulled the BUOY bottle from the side pocket.

The three Liquid I.V. sticks were still perfectly dry.

At 10,384 feet, the answer was sitting inside the bottle she had actually remembered to use.

Buoy vs Liquid I.V. had started as a price comparison in an airport and ended as something much simpler: the better electrolyte product was the one that fit Maya’s real routine.
