24 oz Water Bottle
24 oz Water Bottle with Built-In Cooling Fan
A 24 oz water bottle hits the sweet spot most people are actually looking for — big enough to last through a workout, a workday, or a hike, without being too bulky to carry. HandFan's 24oz lineup pairs that ideal size with insulated stainless steel and a built-in cooling fan, so your bottle keeps your drink cold and you comfortable at the same time.
Shop 24 oz Water Bottles Compare Both ModelsIf you're searching for "24 oz water bottle" or "water bottle 24 oz," you've likely noticed that most options on the market are either plain insulated tumblers or flimsy plastic bottles. HandFan offers two different takes on the 24oz size, both built from stainless steel and both equipped with a rechargeable, washable cooling fan — but designed for slightly different ways of carrying and using them.
Why a 24 oz Water Bottle Is the Size Most People Actually Need
The Balanced Size
Large enough to skip constant refills, small enough to not feel heavy in a bag, hand, or cup holder all day.
All-Day Cold Retention
Double-wall vacuum insulation keeps drinks cold up to 24 hours, so a morning fill is still refreshing by evening.
Built-In Cooling Fan
Both 24oz models include a rechargeable fan you can point straight at your face whenever the heat picks up.
Stainless Steel Build
Food-grade, BPA-free stainless steel resists rust and dents, built to handle gym floors, trails, and daily carry.
Straw-Friendly Drinking
A wide-mouth, leak-resistant straw lid makes one-handed sipping easy during workouts, drives, or work shifts.
Easy to Clean
Fan components are IP67 waterproof or fully washable, so rinsing the whole bottle under the tap is no problem.

24 fluid ounces works out to about 0.71 liters, or roughly 3 standard cups of water. For context, that's close to the volume of two 12oz soda cans combined — enough to keep most people hydrated through a typical 60 to 90-minute workout, a half-day hike, or a busy stretch at work without needing a refill.

Stainless Steel 24 oz Water Bottle: Why It Matters
Both HandFan 24oz models use food-grade stainless steel rather than plastic. A stainless steel 24 oz water bottle resists rust, doesn't pick up flavors or odors over time, and holds up to drops on gym floors or trail rocks far better than plastic alternatives — while also being the material that makes the insulation actually work.
Insulated 24 oz Water Bottle: What You're Getting
An insulated water bottle 24 oz in size relies on a double-wall vacuum gap between the inner and outer steel walls to block heat transfer. That's why the Proof Vacuum model holds cold drinks for up to 24 hours and hot drinks for up to 12 — the vacuum layer works in both directions, so your bottle performs the same whether you fill it with ice water or coffee.
24 oz Water Bottle with Straw
Both bottles in this lineup pair well with a straw-style lid for one-handed drinking, which matters most when you're mid-rep at the gym, gripping a steering wheel, or moving on a trail. A wide-mouth straw also makes the bottle easier to clean and refill quickly compared to a narrow screw-cap spout.
