Level up your drink experience with the VSSL Insulated Flask. Engineered to address common issues of traditional flasks, the VSSL Insulated Flask keeps your drink exactly the temperature it’s supposed to be with double-walled, vacuum-sealed insulation, features a removable drinking cap for easy filling and cleaning, a locking carabiner top for secure carry, and is built tough thanks to 304 stainless steel.

Say goodbye to unreliable, separate tools for booze and music. When we set out to design Insulated Flask, we wanted to innovate the way we enjoyed a drink while listening to music outdoors. This meant solving a few common issues with traditional flasks and speakers. 

The double-walled, vacuum-sealed insulation guarantees that all 8 ounces of your drink stays the perfect temperature. No more whiskey getting heated up from the sun while you’re enjoying your time outdoors.

It keeps beverages hot for 5 hours and cold for 10.

At the bottom of the flask is a fully integrated, weatherproof, Bluetooth speaker.

Developed in conjunction with our friends at Speaqua, it’s top of its class in durable and compact outdoor speakers.

It has built-in sound channels providing great audio, even when placed on a flat surface. 

It also has dual speaker pairing, which lets you sync two speakers together from the same sound source providing stereo sound! Each speaker provides up to five hours of playtime.

We’ve developed a patented leak-proof, and multi-functional drinking cap.

Typical flasks are hard to fill (some even come with a funnel!), but not this one. It has a traditional flask drinking spout AND has the ability to remove the top cap entirely for easy filling and cleaning.

This innovative design provides 2 different drinking methods:

• Thread the stainless-steel flask cap off to enjoy a cold drink from the spout
   
• Thread the full cap off to enjoy a hot beverage

The top cap doubles as a carabiner and easily clips to packs and gear when you need it and folds flat (thanks to magnets) when you don’t.

Built from premium 304 (18/8) stainless steel, Insulated Flask can withstand weather and wear without rusting and doesn’t retain flavors or smells.

It’s compact. Ultra-portable. And fits in the palm of your hand.

Insulated Flask allows you to slow down and enjoy the moment in one sleek system. Complete with a double-walled stainless steel flask, removeable Bluetooth speaker, USB-C charging cable, multi-use drinking top cap, and a flat end cap.

Building the ultimate tool for connection

At VSSL, we make integrated gear systems designed for the outdoors.

Since 2015, we’ve been creating innovative gear that you can take on your most far-flung adventures or carry every day. With your support, we have launched the Camp Supplies, First Aid Supplies, and—most recently—the Java Coffee Grinder.

We believe in well-conceived design. We believe that everything you carry should serve a purpose and if possible, more than one. We use the principles of modularity to create gear solutions for your outdoor pursuits.

We’ve been working hard at developing Insulated Flask over the past 3 years, designing and refining every detail. We’re really proud and excited about the final product.

A drink experience that is so much more than your average drink carrier. The VSSL Insulated Flask is a tool for connection; with nature and the people around you.

Back in 2015, we launched the VSSL Camp Flask here on Kickstarter. We were overwhelmed by the great response and support from our amazing Backers. But we knew this was just the beginning…

We wanted to create a new Flask – one that performs better, does more, and shows the progression in technology. So we made it insulated, added a durable, weatherproof Bluetooth speaker, an innovative drinking cap and much more
