I donned a mask, snorkel and fins and prepared to jump in.

A portable oxygen tank stood next to his bed, and he periodically interrupted what he was doing to lie down and don the mask to gulp air.

Later she donned a mask when the pair went snorkelling.

This was rare though as they would normally only don the masks midway through their matches, and wrestled most of their matches without the masks.

Aviators masks are often equipped with quick don harnesses that allow those in pressurized aircraft to rapidly don the masks in emergencies.
