STEM Vacuum Flask is the new stainless steel bottle you’ll want to take with you wherever you go, on your way to work or hiking up a mountain trail. Conveniently tether it to your pack on the go using the Bottle Leash, and enjoy the modern and spill-proof design of the bottle every time you take a sip. 

Use it as an everyday flask or outdoor gear, as it keeps your beverage hot or cold for up to 6 hours. 

STEM Flasks come in two designs: one with a carrying strap called the Bottle Leash, and one without. The bottle leash lets you hang the STEM from your bag, or comfortably hold onto it as a handle. Please note that the bottle leash cannot be attached to a standard model STEM. 

Now available in modern adventure tones of Black, Ash Blue, Sandstone

Washing Your Vacuum Flask

STEM flask interiors are electropolished to create a smooth, gleaming surface. This helps it prevent the accumulation of dirt, and reduces odor buildup from drinks. Hand wash with water and soap, then air-dry or wipe dry.

  • Avoid direct fire. 
  • Do not place near heat sources such as gas stove, ovens and heaters. 
  • Do not use in the microwave.
  • Do not use in the dishwasher or dryer.
