Firelight Flask 375
Bar Quality, Built for the Outdoors
Built for those who pack light but pour well. The Firelight Flask® 375 packs all the rugged performance of our flagship into a lighter, more portable design. With a half-bottle capacity and one integrated tumbler, it’s the definitive flask for an uncompromised personal pour.
The Firelight Flask® 375 offers the performance of our flagship, forged for the individual. It’s a more compact design for solo adventures, built to the same exacting standards of quality as its larger sibling.
The vacuum-insulated, distiller-grade steel body protects a half-bottle of spirits or a small batch cocktail, guaranteeing a perfectly tempered, flavor-pure pour for up to 24 hours. A single 6-Shooter tumbler—a proper, weighted cocktail glass—attaches magnetically for a sleek, rattle-free carry. Engineered with a wide-mouth opening and a leak-proof cap, the 375 is the definitive personal bar for those who travel and adventure on their own terms.
Our Firelight Flask® 375 fits a full bottle of spirits. Looking for something bigger? Try theFirelight Flask® 750.

Frequently Asked Questions
Explore common questions about the Firelight Flask®. If you have further questions or wish to contact customer service, please email support@highcampflasks.uk
How big is the Firelight Flask™?
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.
Is the Firelight Flask™ just for cocktails and spirits?
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.
How do I clean this flask? Is it dishwasher safe?
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.
What comes inside the box?
All of our flasks arrive in beautiful, high-quality packaging reflective of the premium nature of our product. We think you'll love the unboxing experience, and we think our packaging helps make our flasks an excellent gift for someone else.
Within each box you'll find the following:
- The flask you ordered.
- A protective sleeve for your flask. Use it for storage and for cleaning the cups after you are done with your drink.
- A product use and care instruction manual.
- A recipe for a delicious cocktail or wine punch crafted by our founders. It's a delicious drink for your new flask.
- A magnet warning.

What's up with the ® in Firelight Flask®?
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.
