The covers do mostly prevent it. They sometimes do get a little bit of condensation, but it’s not significant. The cover mostly takes care of it. You can get a little condensation near the sealed end of the bottle. It’s less than the amount of moisture you would generate via sweating.
It doesn’t leave wet patches. If you used the bottle without the cover, it would. But the cover makes it so that heat energy only slowly leaches into it. In other words, the surface of the covered bottle is probably around 60F/16C. And the surface is fluffy, not smooth.
Doesn’t this leave you with wet patches in your bed though?
I think the bottles are sealed.
Water condensates on cool things and the body loses water vapor through pores.
I think the covers on the bottles should mostly prevent that though.
