"it slowly dawned on me that the landscape of science is maybe what interests people a great deal in science fiction."
- Gregory Benford

Eando Binder didn't think much of them, as seen in this quote from Murder on the Asteroid (1933):

Their faces were red and puckered, not only from the coolness they constantly lived in, but also by reason of the many times they had ventured out in vacuum suits. The constant use of these suits was influential in promoting skin troubles and stomach disorders, for they were the acme of stale, uncomfortable, unhealthy confinement.

And from Tidal Moon by the Weinbaums:

Amherst zipped the parkalike garment closed about his long, muscular body, pulling the sillicellu visor before his rugged features before he stepped from the autobus. The cold was penetrating. Even vacuum suits — misnamed, for they did not work on the principle of the thermos bottle but had the inner layer held from the outer by thin, radium-warmed wires — were scant enough protection.

Here's another quote Using this phrase from Diamond Planetoid (1939) by Gordon Giles:

...he zippered shut his neck-piece.

He stood still while Welton fitted the glassite helmet over his head and smeared instant-drying rubber cement over the zipper runs at the shoulders and neck. After clamping an oxygen bottle to Osgood's back and connecting the triple tubes, Welton came around to the front of the grotesque figure in micromesh rubberized silk...

Welton watched the bloated vacuum suit, inhabited by his friend, crawl slowly and carefully over the microbe world of rock. He looked like a gigantic black frog in the dull Saturn shine.
