He's recently come close to dying in various painful ways. Clothing is very low on his list of important things.

Pulling his canteen off, he takes a drink, then sighs. "Some people try to get free and wrench something even worse when they do--and then go wandering off on it. And even if you're used to living in the country, Garados can be tricky on his calmest days--to say nothing of when Thana Lilvia gets angry."

He offers the canteen to Alec. There's no telling how long the kid had been out here without water.
