Adam Clarke on Isaiah 66:20

And in chariots "And in counes" - There is a sort of vehicle much used in the east, consisting of a pair of hampers or cradles, thrown across a camel's back, one on each side; in each of which a person is carried. They have a covering to defend them from the rain and the sun. Thevenot calls them counes, 1 p. 356. Maillet describes them as covered cages hanging on both sides of a camel. "At Aleppo," says Dr. Russell, "women of inferior condition in longer journeys are commonly stowed, one on each side of a mule, in a sort of covered cradles." Nat. Hist. of Aleppo, p. 89. These seem to be what the prophet means by the word צבים tsabbim. Harmer's Observations, 1 p. 445.
