We make two sizes of Firelight Flask®. With it's 750ml capacity (25.4oz), the Firelight Flask® 750 fits an entire bottle of spirits or several cocktails, and comes with two integrated tumblers. The smaller Firelight Flask® 375 fits exactly half of that (375ml // 12.7oz) with one integrated tumbler.

If you want a smaller flask, our take on a traditional 'pocket' flask, we recommend you explore our Torch™ Flask.

We designed the Firelight Flask® with spirits and non-carbonated cocktails in mind. We feel it's the absolute best way to pack and share a craft cocktail or premium spirit after your adventure, during a picnic, at the beach, around the campfire, and more. But the Firelight Flask also works great for things like coffee, pressed juices, even water. Having a real tumbler to drink from is a nice perk compared to a normal stainless steel drinking vessel. Ultimately the Firelight Flask® can be used for any non-carbonated and non-dairy-based beverage.

If you are more into wine, we recommend you check out our stylish Parkside Flask™.

Note* We do not recommend putting carbonated or dairy beverages in your Firelight Flask®. The pressure build-up from these types of beverages can damage the threading of the cap and render the flask unusable. Any damage related to carbonation will void the product's warranty.

To clean your flask, rinse it with warm, soapy water right after you finish your drink. Then, turn it upside down to let it dry completely before reattaching the lid. The flasks are not dishwasher safe; we recommend hand washing them for the best care.

Great question. Many stainless steel drinkware companies are awash with sameness, often sourcing existing designs from large overseas factories. We prefer to innovate.

The Firelight Flask® is our flagship product—it’s the one that launched the brand. We designed it from the ground up to solve a real problem: there was no great way to bring a bar-quality drinking experience into the outdoors. We hold patents on our unique magnetic tumbler system, and High Camp Flasks is the only place you'll find an adventure flask built like this.

That little ® signifies that it's a registered trademark, which is our commitment to originality. It’s a small detail, but it represents our promise to deliver the most innovative and durable adventure flask on the market.
