Most insulated flasks have plastic built into the body or worse, inside of the lid - not this one! Plastics can leach hormone disrupting and other chemicals into food. How happy we are to launch this flask with body and lid made entirely of high-quality rust-proof stainless steel. This thermal container is a delight for carrying soups, chili, hot cocoa, miso, hot rum toddies and so much more! Note that there is a high quality, thin silicone seal in the lid to keep it leak-proof and backpack safe.

Why you will like it:

  • It is completely plastic-free, even the lid interior;
  • It is made of high quality 18-8 food grade stainless steel;
  • It is made to last forever;
  • It is compact and may contain up to 11 oz (350 ml) of hot food;
  • It features a handle to carry with ease;
  • It is designed to prevent plastic chemicals from leaching into your food;
  • It is just plain beautiful to look at!
  • It is double walled and vacuum insulated.
  • It keeps the temperature! According to our tests with boiled tea, it stayed hot for 3 hours and after 6 hours was still warm!

Thermos is perfect size

I bought 2 of these and they work perfectly. Keeps soup hot and ice cold almond milk cold. Only thing I've noticed, and it by no means effects performance, is that the grove where the handle is attached, collects with water, after washings. You need to turn the lid sideways and jiggle the handle a bit, to let the water out. Other than that, it's really well made, to last.

Sturdy and keeps soups hot

I got this for my teenaged son for his school lunches...mostly soups. It keeps them nice and hot until lunchtime and he likes the simple design and handle. Only downside is that it can sometimes leak, so we always do a "leak check" before it leaves the kitchen...sometimes having to rinse the silicone seal inside the lid and re-seat it before tightening the lid again. I think that you need to be able to order replacement seals for the lid, because you need to separate the ring to thoroughly clean the lid and I just know one of these days we're going to lose the ring while it's drying out. Also, be aware that water can get into the lid where the handle meets it, so don't immerse it in water for too long. A nice thermos...with a few tweaks it would get 5 stars from us! Hi Becky! Thank you so much for the feedback! Sometimes the fit of the lid can affect the seal so great idea to do a leak check and re-fasten the lid until you get that airtight fit. Definitely great input about the lid and the replacement ring that we will keep in mind for the future as we always strive to bring the best plastic-free products forward. Thanks so much!
