Some models include a carrying case, but I'm not sure I'd describe them as "very portable". For example the Glove80 has a hard-shelled case, but the case itself is probably bigger than most laptops. The Moonlander packs smaller into a soft case that folds like a wallet, but it's less protective.
There are designs with far fewer keys that could probably be carried around more easily, but then you have to learn their layer/chording system.
The Svalboard has an extra issue that some folks prefer it to be placed below desk height, such as attached to a chair or sitting on an under-desk shelf, so it's not something you can generally just put on a table in front of the computer.
