[If Isaac shows any sort of discomfort to Tim's smoking habits, he's not showing it. Though he kind of holds back a chuckle at calling it a bike helmet.]

This 'bike helmet' is all I've got of a suit that'd be a lot more useful than anything we've found here - they're called RIGs, they're meant to work in outer space - but the one I had was coincidentally pretty good at keeping out the cold.

Here, it's just a nice helmet with a built-in light that occasionally keeps my head warm.

[He picks it up and inspects it, shrugging.]

Guessin' you've never seen much like that back home?
