• Usually only the one, but if I’m going to run a game I’ll bring several sets because there’s always someone (possibly more than one) who doesn’t have one.

    And yes, there’s no insulation anywhere here. The walls are mostly concrete (with plaster, etc. over top, natch) and when cold weather hits actively start to radiate cold. (I know, I know, technically they’re sucking heat out, but it FEELS radiative!). All the windows are single-glaze and they’re not particularly well-sealed either, so drafts are common.
