Single-wall bottles sweat, and your drink goes flat-warm by lunch.
The vacuum gap is what does the work. With no air between the two steel walls to carry heat across, the bottle does not sweat onto a bag and the drink holds its temperature far longer than a single-wall flask — cold for around 24 hours, hot for around 12.
The mouth is wide enough to drop in ice and to reach in and clean, the lid seals against leaks for a bag, and the powder-coated outside grips dry in the hand. Inside it is 18/8 food-grade steel, with no plastic touching the drink.
