Butelka Summit z nakrętką ze słomką

Left it in the car on a 90-degree day and the water was still cold hours later, so the double-walled insulation really does the job. The straw lid clicks shut tight enough that I tossed it in my bag without a leak, which is exactly what I needed for commuting.

The straw lid is surprisingly sturdy and seals tight enough that I can toss it in my work bag without worrying about leaks. I’ve had this for a week and the ice is still lingering hours after I fill it.

The double-wall really does keep my water icy for a full workday, and the straw lid’s close function has survived a few tumbles in my bag without leaking. Only wish the mouthpiece were a bit wider for easier cleaning, but otherwise it’s a solid daily bottle.
