IRON °FLASK Classic Tumbler 2.0 - 24 Oz, 2 Lids (Straw/Flip), Vacuum Insulated Stainless Steel Bottle, Modern Double Walled, Simple Thermo Travel Mug, Hydro Water Metal Canteen - Cotton Candy

Very convenient Leak proof

This is the best tumbler I have every owned. It is extremley well designed. Even the darn straw is designed to be air tight going into the lid. You can put ice it at 9 pm, and the next day the ice is still there and the water is still ice cold. This cups thermal engineering puts others to shame. I own a Yeti, yes they are good, but this cup is even better. You can sit outside on a hot summer day with your ice lasting longer than the water, and no condensation build up at all. Its extremley durable and solid, able to withstand drops without a dent.

Keeps things cold and warm for a good amount of time. Very Satisfied

This is my second purchase. First one did not arrive and i was required to purchase a second one at a higher rate. Message read it was damaged in transit. No fault to the company. I love my new cup. I use the straw cap and drink 3- (37oz) of these daily to get my daily water intake. The are durable, almost completely leak proof and they keep my water cold for hours. I will definitely purchase again in the origional color I was looking for. I highly recommend this product.

I've had the 32oz Calacatta Iron Flask for a little over a month now. I never go anywhere without it. I love how long it keeps my water cold. It's very sturdy and doesn't leak unless you flip it over. But even then, it's much less than a regular cup would be. I don't have an issue with the straws like other people have complained about. I also haven't had any issues with the lid (I don't use this for coffee so I haven't used the coffee lid). The Calacatta is a smooth satin finish. It looks matte but has a slight shine that shows off the gold. It's beautiful. I also love that the 32oz still fits in my standard sized car cup holder. I fill it up halfway with ice and then add cold water. With that much ice, it usually fits about 18- 22oz of water. That ice will last up to 24 hours depending on how much you refill the water. I always refill with cold water to make the ice last longer. Keep in mind, water slushing around and frequent refills will melt the ice faster, but the water will stay cold for hours regardless.
