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!"

Love my Firelight Flask 375

It is beautiful, well designed and very practical for carrying your favorite spirit or cocktail. This will be traveling with me everywhere I go. I probably have the first Firelight Flask to see the sun setting in the coffee mountains of Colombia while sipping a G&T.

Excellent Product

Well thought out and very well constructed. I’ll be giving some as gifts this year.

Hidden gem

Small compact little take along that holds just the right amount for that special occasion.

High Camp = High Class

This is an exceptional flask. I considered using it as a water bottle occasionally but it's too nice so I opted to fill it with Lagavulin 16 instead.

It has a nice weight to it. Especially the stopper. It's made in China but the quality is top shelf and the Scotch style presentation box is a nice touch.

Michael Grant
Very pleased, as expected!

I quite like the Firelight Flask I ordered. It is the size I expected from reviewing the images of it in their website and is just what I was looking for. Cup is held in place with a strong magnet which I like. It’s not going to fall off. The screw-on cap has rather short travel distance before tightening up but it is water tight as noted when washing it initially and ultimately Scotch tight as well. Not expecting to make use of any insulating properties with hot or cold beverages but it has a nice weight. A backpacker would use something lighter, but this will be great for trips in my Sea Kayak or Canoe, or car of course. I got the stainless version and am pleased with its appearance.
Thank you Highcamp
