IRON °FLASK Classic Tumbler - Vacuum Insulated Stainless Steel Water Bottle, Double Walled, Drinking Cup, Insulated Travel Mug (Aurora, 32 oz Solid Lid)

Works well. Very durable. Two lids are a bonus.

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.
