When the temperature outside begins to rise, the temperature of your drinks should drop. Whether you’re traveling somewhere hot for vacation, approaching the warmest months of the year, or preparing to spend a few hours getting sweaty at the gym, staying hydrated with ice-cold water is one of the best ways to regulate your body temperature. Don’t rely on disposable plastic water bottles that are bad for the environment and will only stay cool for a few minutes. Instead, invest in a reusable hot weather thermos that will keep liquids cold for hours.
A hot weather thermos is typically designed with double-wall insulation that keeps the contents icy cold for hours without heat transfer, meaning the outside of the bottle stays dry and free from sweat. Easy to clean and often able to be used for hot drinks as well, hot weather thermoses provide cost savings, convenience, insulation, and lessen the environmental impact that comes from disposable water bottles.
If the hot weather is approaching, it’s time to sit back and sip on something cold. Check out four of our favorite hot weather thermoses that will help you keep your cool.
1. Hydro Flask Wide Mouth Water Bottle
For a thermos that can be used in all four seasons, try the Hydro Flask Wide Mouth Water Bottle. The Hydro Flask has double-wall insulation that keeps beverages cold up to 24 hours and hot up to six hours. The sweat-free bottle doesn’t transfer temperature, which makes it comfortable to hold regardless of the contents. Hydro Flask uses 18/8 stainless steel that won’t transfer flavors and is free from BPA and toxic chemicals. The Hydro Flask is available in multiple colors and can be used with a wide mouth flip lid, a wide flex cap, or a straw lid, which is shown here.
Pros: The outside of the Hydro Flask has a powder coat that is scratch-resistant and provides a slip-free grip.
Cons: The Hydro Flask’s lid is not leakproof. It also comes with a big price tag and hot beverages should only be used with the Wide Flip Lid, which must be purchased separately.

2. The Coldest Water Bottle
When the temperature spikes, staying hydrated with cold water is imperative. That’s why we like the Coldest Water Bottle, which comes in a 64-ounce growler-sized jug. The heavy-duty bottle comes with a matching heavy-duty leak-free cap that is designed with a handle for easy. The BPA-free, odor-resistant, double-wall stainless-steel bottle keeps water cold without transferring sweat to the outside. The durable bottle includes a rubber grip and it can float, making it a great addition to water workouts and pool parties.
Pros: The wide mouth opening on the Coldest Water Bottle makes it easy to add standard-sized ice cubes.
Cons: The Coldest Water bottle comes with a big price tag and it’s too wide to fit into a standard cup holder. The Coldest Water Bottle has a straw lid available, but it must be purchased separately.

3. CamelBak Chute Mag Water Bottle
No more lost lids with the CamelBak Chute Mag Water Bottle. The Chute Mag is designed with a durable plastic handle that includes a loop for easy carrying and an angled spout for comfortable drinking without any sloshing or spilling. The lid on the spout is magnetized and stays out of the way while drinking and easily attaches when the bottle is not in use. The Chute Mag can be used with both hot and cold liquids and double-walled vacuum insulation makes the bottle sweat-resistant, keeping hands comfortable. The Chute Mag’s cap easily threads for a secure close and the cap can be fully disassembled for a thorough cleaning.
Pros: CamelBak offers a wide range of sizes for their Chute Mag Water Bottle, including 12, 20, 32 and 40 ounces.
Cons: The Chute Mag’s magnetic cap can interfere with pacemakers and the lid is not leakproof.

4. Healthy Human Water Bottle
It’s not often that we described a thermos as beautiful, but the Healthy Human Water Bottles are beautiful. The company offers solid, bold colors as well as stunning patterns, including wood-based designs and fun art-deco patterns. Available in a variety of colors and sizes, including 16, 21, 32 and 40-ounce bottles, Healthy Human’s water bottles are made with 18/8 stainless steel and feature a steel-lined lid. The thermos can be used for all types of drinks and will keep liquids hot for up to 12 hours and cold liquids cold for up to 24 hours.
Pros: Healthy Human makes water bottles that are sweat-proof and leak-proof.
Cons: The bottle dents easily. The lid will leak if not placed on tight enough and the seal weakens over time.
