FAQ

Is it waterproof?

Yes it can! Monti's are lined with a waterproof interior
How long can it keep ice?

At room temperature your Monti can hold a temperature below 36 degrees for 10 hours. Should be plenty of time for you to finish those frosty drinks.
How does it work?

Your cooler has a built in stuff sack for when you're not using it. Not using it? Simply stuff your cooler into it's pocket. When you're ready to go, just pop it out and add ice!
No zippers!? How do you close this thing?

Roll the top of your cooler a minimum of 2 times, then clip shut. 3 rolls is even better. It's as easy as that!
I already own a fancy cooler, what makes Monti different?

We love our Yetis! It is great as a mothership in the car or house. When it comes time to go out on a hike, fishing, park day, grocery run, or anything away from traditional heavy coolers, that is the perfect time to grab your Monti! It's the cooler you actually want to take with you everywhere you go. #bettertogether
