I use this as a growler and my beer stays icy cold.

Does the job

  • Familiarity: I've used it several times

Initially I had a problem with the seal but after some tinkering it worked as advertised. Keeps beer cold and seems to prevent it from going flat for a day or so. Not more.

Like Greg said below the lid is not easy to get off when filled with beer, but once you get it off it super cold and well worth the struggle!

All Day strong

  • Familiarity: I've put it through the wringer

I bought this to take to the rock climbing gym, crags and other remote events. It lasts all day for me. it doesn't chip off or dent up like I expected. There is no metallic taste to the drink inside even when it is heated to 100 degrees.

I got it for Beer.

  • Familiarity: I've used it several times

Yep.. It's for beer. I am not using it for anything else.

I took it to our local brewery and had the rather large and buff Barmaid fill it. When I got home I had a really hard time getting the lid unscrewed. I thought she used her large arms and man hands to wrench that thing down to make it difficult on me. Nope, after I poured a glass and screwed it back on the next time I went back for a refill I had the same issue again. So the pressure of Beer does make getting the lid unscrewed a bit tough.

The Barmaid said she used one and said it keeps beer cold for like 30 hours. My beer didn't last that long.

I will add this.. Don't be surprised when you go to get your growler filled that you have people walking up to you asking where you got it. I have been stopped multiple times by people as I am leaving or waiting for it to be filled.

Backcountry doesn't carry the accessory lids for these insulated bottles but REI does. The flip up straw one is nice to sip drinks of beer without needing to pour it into a mug and it kinda keeps your beer personalized with your backwash going back down into it. They also have a flip top lid that you see on many insulated coffee mugs. Now you can drink straight from the thing and still keep your beer cold.

it rocks

take a growler of your favorite beverage on a picnic. This puppy does exactly what it is supposed to do. Filled it up at the local and 24 hours later the brew was still cold. Put a goat sticker on it!

For lovers of yoga & beer

  • Familiarity: I've put it through the wringer

This 64oz flask has become a personal fave. Perfect for 90 minute hot yoga sessions & for lugging tasty, ice-cold beer into the sticks. The thinner neck allows for one hand carrying/handling.
