text: High-quality jar and silicon carrying sleeve/lid! The whole kit makes taking a sustainable, reusable jar easy to use all the time, even on the go! The sleeve does well enough to maintain the temperature of the liquid in it. It doesn't completely insulate the user from extra hot liquids, but that just may be my low heat tolerance at work. Excellent craftsmanship all around! Use it almost everyday!
  Love to be able to add hot water and have tea all day
