Full Description

Experiece a bar-quality drinking experience in a go-anywhere package. The updated Firelight Flask® 375 improves on our original 375ml flask with new features that allow you to pack and enjoy your favorite beverages even easier.

A new diamond-grip cap makes for effortless opening and ensures you get a leak-proof seal closure while the wider mouth accommodates larger ice cubes and easier filling. With the new Firelight Flasks, we're excited to launch updated tumblers. Now vacuum insulated just like the flask, these tumblers offer even more temperature control and a guaranteed sweat-proof grip.

The core features of the Firelight Flask® 375 remain. It will fit half a bottle of sprits (half for me, half for you), or 12.7 ounces of your favorite beverage. The integrated tumbler magnetically attaches to the flask securely and near seamlessly. The electropolished kitchen-grade stainless steel interior will not impact the flavor of your drink and cleans effortlessly. With this update, our innovative personal adventure flask is even better. You'll love it for your favorite spirits, cocktails, even coffee!

"I've used my Firelight 375 camping at the beach in Santa Cruz, then up to the granite peaks of Yosemite, as well as a Thanksgiving trek down the street to have a drink with my buddies...such a great product. And great service as well!"

I’m impressed with this product.

I’m impressed with this product. Very high quality and will get a lot of use out of it. The build quality is excellent.


Love how long it keeps cold drinks cold, the cup that’s attached to & the flavor is pure! No metal taste interference.
Because I viewed several models, I thought the bottom opened up to put large round ice in.
Our son first purchased his last year & spoke so highly of it, I kept it on my watch list & purchased a set for our recent 41st anniversary!!


Fantastic quality!

Paul Cohen
Good but could be better

Would be nice to have a way to put ice in it. The top opening is fairly small. Maybe the bottom can screw off with a larger opening.

Best flask ever
