Well, I guess it's more of a cooler/thermos. It is freaking heavy duty! This thing is solid and is not a lightweight in the water bottle arena. It has a nice grippy coating. Even though it is large, coming in at 40oz, I am able to easily hold it in my hand without issue. I really like that it has a rubber edge on the lid so that it's easy to get on and off. I have a couple bottles like this that just have the metal top and sometimes twisting it on and especially off is difficult. This is a wide-mouth bottle so adding ice is a breeze. But be warned that drinking while driving can cause spilling on your clothing...haha. Trust me... Sometimes I only have a finger, and so I can still pick up my drink easily and securely. I got the black colour and it is nice. This is a great water bottle and it's extremely durable. It rolls around the floor of my car all the time while I drive around to appointments. It doesn't spill, dent, or cause me any worry. I'll list some features here: 1. VACUUM INSULATION: This KOVOT water bottle uses double walled vacuum insulation technology, meaning the space between the stainless steel walls is void of matter. With no medium for heat to transfer, your drink's temperature will not be impacted by the temperature outside the container. 2. COLD UP TO 24 HOURS|HOT UP TO 12 HOURS: KOVOT's vacuum insulation will keep your drink cold up to 24 hours and hot up to 12 hours. 3. SWEAT AND BURN FREE: The double wall vacuum insulation prevents condensation from ever forming on the exterior. Hot liquids will not impact the bottle or tumbler's exterior either. This means the drink ware will always be comfortable to hold and never make a watery mess.
