Hydro Flask 32 oz Travel Bottle with Flex Straw Cap
A 32 oz insulated bottle that actually fits a car cupholder
A 32 oz stainless bottle with a tapered, cupholder-compatible base, a leakproof Flex Straw Cap and TempShield double-wall insulation that keeps drinks cold for up to 24 hours. Dishwasher safe.
Our take
Here's the problem with most 32 oz bottles. They're too wide for a car cupholder, so they end up rolling around the footwell. This one has a tapered base made to fit. Fill it once in the morning and the insulation keeps it cold for up to 24 hours.
That's the whole case for a road trip or a long travel day. A full quart within reach, and a straw cap you can sip from with one hand while driving. The downside is weight. It's 1.2 lb empty, which you'll feel in a carry-on or on a long walk. The straw cap has more parts to clean, and it has few reviews so far, though the insulation and cap are standard Hydro Flask.
If you drive more than you walk, this is the one we'd buy. Check the price before your next road trip.
Who it’s for
Road trippers and long-haul travelers who want a full day of cold water that fits the car.
Skip it if
Skip it if you walk a lot or pack light. A smaller insulated bottle or a light plastic one is easier to carry.
Hydro Flask 32 oz Travel Bottle with Flex Straw Cap: questions people ask
Do 32 oz bottles fit in car cupholders?
Most don't, because they're too wide. This one has a tapered base made to fit standard cupholders.
How much water should I drink on a long flight?
Cabin air is dry, so keep sipping through the flight. Fill your bottle after security so you're not waiting on the drinks cart.
Is an insulated bottle worth the extra weight?
If you want cold water all day, yes. If you just need water, a plastic bottle weighs far less.

The right size for road trips and city days, but the straw lid is more work to clean in a hotel sink than a screw cap.
