Excellent beverage heat retention
Purchased this traveler bottle yesterday. I put boiling water in it to make some tea. 6 hrs later the water was still to warm to drink comfortably. Today, it's been 4 hrs and when I removed the lid, it was still steaming. Externally, it's warm near the lid and cold at the base. This "thermo" bottle is one of the best made.
Great product from REI
