Hydroflask Pints and Bottles
We happened to learn about the Hydroflask line of products by total luck. We signed up for a monthly delivery box service called Cairn, and as luck would have it, the first box we received had these awesome tumblers in them. I got blue, Kim got brown. This worked out well for out taste in colors. To be honest, at first, I was a little peeved - I didn't need two random tumblers taking up space in my tiny southern California kitchen. At the same time, I loved the design and how it felt in my hand.
That night, we poured a couple of cold beers into these tumblers to test them out. I should also say that I am a slow beer drinker when I'm drinking beer at home. This causes me a lot of warm beer heartache. This tumbler saved the night. My beer stayed cold way longer than it should have.
Since then, it has gone to the beach and kept beer cold, even in the sun. It has gone camping and kept beer cold while huddled around a campfire. It has spent many evenings on my coffee table, keeping my beer cold at home. (It also works for tea, water, etc., not just brews.)
We actually liked these cups so much that we quickly added to our Hydroflask inventory. We also have the 32 ounce wide mouth bottles, 21 ounce standard mouth bottles, and 18 ounce coffee tumblers. Without fail, they are the best bottles we've owned. I've taken ice on camping trips and still had ice in my bottle 24 hours later. My coffee stays warm every morning while I slowly sip it. The 21 ounce bottles fit on our bikes and keep nice, cold water handy on longer rides. We added the "sport cap" for the bike and it makes drinking convenient. Next on the list to buy... a growler to keep all of the beer cold at once! :)
They are durable, they work, and they are nice to look at. They don't sweat and make your pack all wet. They are vacuum sealed and insulated and they make great noise makers to scare away bears, but also use that science to keep hot things hot and cold things cold. They also come in lots of colors! And the company behind the cup is pretty nifty, too.
(This is an unsolicited review. Hydroflask gave us nothing and did not ask for feedback. They likely don't even know who we are. But we know them, and we like them.)
