Double Wall Glass Mug With Borosilicate Insulation

Two Walls, One Clever Air Gap

Air gap that keeps heat in

Two glass walls with an air gap between them slow heat transfer. Your coffee stays hot through the morning, and the outer wall stays cool enough to hold without a sleeve. Pour in the drink and the mug does the rest.

Borosilicate glass, polished rim

High borosilicate glass is the material behind this mug. The rim is smooth and polished, so it feels clean on the lip, and the glass has a glossy finish that looks as good on a desk as it does in a kitchen cupboard.

A handle made for everyday grip

The C-shaped handle gives your fingers a clear place to rest, away from the warm body of the mug. It is sturdy enough for a full cup, and it keeps the sipping hand comfortable from the first cup to the last. Pair it with a insulated travel mugs collection if you want a second option for the commute.

Your first cup in three steps

1. 1
   Warm the glass

   Rinse the mug with hot tap water for a few seconds. A warm mug takes the shock out of the first pour.

2. 2
   Pour in gradually

   Add your coffee or tea slowly so the glass warms evenly. Latte layers look best poured this way.

3. 3
   Hold it by the handle

   Lift the mug by the C-shaped handle while you sip. Your fingers stay off the warm body and the drink stays warm longer.

Hot mugs have always been a compromise

The burn you stopped noticing

You fill a plain mug with fresh coffee, grab it by the body, and fumble it back down to the desk. By the time you find a free minute to drink it, the coffee has gone lukewarm. Most people have just accepted this as the cost of a morning.

Two walls, one clever gap

The mug is built from two layers of borosilicate glass with an air gap between them. That gap slows heat moving out through the wall, so the inside stays hot while the outside you hold stays cool. The C-shaped handle keeps your fingers away from the warm middle.

Your drink, finally visible

Clear glass means you can see the color of your tea, the layers in your latte, and how much is left in the cup. You stop guessing when to refill and start enjoying the drink you actually poured.

What to expect over time

1. First use
   Feel the cool outer wall

   Fill it with hot coffee or tea and notice the outer glass stays cooler to touch than a single-wall mug.

2. 3 uses
   Find your routine

   Most people settle on a favorite drink and a spot on the desk or counter. The clear glass shows when the cup is nearly empty.

3. 30 days
   Becomes the everyday mug

   With regular hand washing the glass stays clear and the rim keeps its polished look. This is when the old mug usually gets put away.

Keep the glass clear

• Hand wash

  A soft sponge and mild dish soap are all it needs.

• Warm it first

  Rinse with hot tap water before pouring boiling liquid.

• Skip abrasives

  Scouring pads can scratch the polished surface and dull the glass.
