Newest technology with a top of the head tube design for a comfortable fit. This gives you the freedom to sleep in many positions and designed to leave your face clear, so you can wear glasses to read or watch TV.

Air flows through the SpringFit frame for a soft yet secure cradle seal, that adapts for a personalised fit.
