Now I need to take a towel with me! I suppose I could leave that extra baselayer behind and use the towel for for warmth as I ride across the cold moons of Jaglan Beta (they're near Mach aren't they?)
.... woops. I'll take that back. "Sanitary towels and incontinence pads routinely use superabsorber powders which turn to gel on contact with water. Naturally, should these enter the bloodstream they can present a critical risk."
Maybe just an ordinary towel then.
