| The tubing *does* squash, and allows air to migrate very slowly. Enough to keep the glove roughly equalised, but without allowing any sudden movements of air or floods of water should the glove leak.
And of course, if the glove does leak then of course the tubing isn't such a good idea, but then if your hand is wet then you might as well remove the glove anyway, and you can pull the tube out - if you do it when you first notice you shouldn't get a wet arm, and if you stick the glove back on they can actually be pretty warm even when completely soaked (like a wet glove, essentially).
That said, they still shouldn't leak in the first place. If your gloves have holes in then you can replace (on the ring systems) the actual glove bit for £3-£4 per pair, so no reason not to. I even saw some in Homebase recently, although they were about £9 I think.
