Ideus insulated mugs
A handle, a lid and coffee that is still hot after the second meeting.
Choosing an Ideus mug
The mug is where this range started and it is still the piece most people arrive for. Sixteen ounces of vacuum-walled steel with a handle on the side and a press-in lid on top, in more colours than anything else on this site.
Two things are worth knowing before you buy. The first is capacity: sixteen ounces is the vessel, not the drink. With the lid pressed in you are pouring about twelve ounces of coffee, which is a mug of coffee by any normal reckoning but is not sixteen, and the gap surprises people who measured their old cup.
The second is the lid, and this site would not exist if it were simple. The listing describes a press-in lid with a silicone gasket and a splash-proof sliding cover, and then says plainly that it is not leak-proof. That is exactly right and exactly worth repeating: this is a desk piece and a car-seat piece, not a rucksack piece.
| Piece | Lid type | What the maker says | Into a bag? |
|---|---|---|---|
| 14 oz coffee mug with a handle | lid | Not stated the listing makes no claim about this lid, so we make none either | Unknown. We would carry it upright. |
| 16 oz coffee mug with a handle | sliding | Splash-proof the maker calls this a splash-proof lid and states in the same listing that it is not leak-proof | No. Carry it upright. |
