Zojirushi 34oz Stainless Steel Tumbler Charcoal Black

Great! A gift for our son. He loves it. The hot water stays warm for 3 days.

This bottle is fantastic! You can keep water hot or cold for many many hours. The bottle seems to defy physics and i really like the handle straiht on top rather then offset like other bottles. The one companion item I wish exists is silicone grips for better grip and less slippage from the side of the backpack.

Very well made, solid, with great capacity, and it is easy to clean. The handle is so convenient. The only complaint is that it does not pour well, e.g. into a mug, and always drips. This is a difficult problem to avoid in my experience, but just something to be aware of.

I've been looking for a water bottle that has easy to clean parts, especially the lid because I can't stand other water bottles that have the o-rings. They are impossible to take out to clean and puts it at risk for mold. This kid is just one piece that is very easy to clean! The bottle itself is great - keeps drinks pretty cold and hot, though I will say it doesn't keep iced drinks as long as some of my other brand double wall insulated bottles. However, it's fine for how I use it. I hope they continue to make mugs and bottles like this with hygienic easy to clean parts! Really benefits everyone's health!

- It's easy to clean. - The wide mouth opening feels great to drink out of. - The paint texture on the Mineral Gray (HM) feels nice and is easy to grip the Stainless bottle. - The build quality of the Stainless bottle is great. - Slicksteel interior is always a nice touch. <3

Excellent Vacuum Flask, absolutely need to have a second cup to let anything hot you put in to cool off. Still scalding hot after 8 hours. Haven't really tested how long it stays hot because I like my tea, but it's probably at least 12 hours minimum for it to remain scalding hot.

Reasonable price and solid quality. Used it for cold brew tea. Just need to add ice and water with tea and leave the bottle over on the counter overnight. No fridge needed. Then I can enjoy cool brew tea for the next day without worrying temperature raising especially during this super hot summer time.

Amazing temperature retention, easy to carry, and the sleek look- what's not to like? Kept my water cold during workouts and the big volume keeps me on alert to drink more water. A big fan of the product!
