The ScubaPro Compact Mouthpiece, also known as the Super Comfort mouthpiece, is a smaller-profile replacement mouthpiece built for divers who find the standard size too large or fatiguing over long dives. It's made from high-flow black silicone and was introduced alongside the S620 second stage, though it fits all current ScubaPro second stages rather than being limited to a single regulator model. The reduced size gives a more secure bite grip, aiming to cut down on jaw strain during longer or repeated dives.

Installation follows the standard replacement process for a second stage mouthpiece, fitting over the existing bite tabs and secured with a mouthpiece clamp. As a factory replacement part, it's suited to divers replacing a worn or torn mouthpiece as much as those switching from the standard size for comfort reasons. The silicone construction is designed to resist deterioration from repeated saltwater exposure and biting wear over normal service life.

This mouthpiece is compatible with ScubaPro second stages, including the S620Ti and other current models. Divers unsure whether the compact size will suit their jaw and bite pattern should compare it against the standard ScubaPro mouthpiece before committing to a switch, as fit is a matter of individual preference rather than a universal upgrade.
