Aishah Rahman –
Is the mouthpiece suitable for people with a smaller jaw? I find many regulators uncomfortable after a while.
Junhao Lo –
Hi Aishah, the Seac Octo Synchro Regulator is fitted with a hypoallergenic silicone mouthpiece designed for comfort and flexibility, making it suitable for a variety of jaw sizes. If you have specific comfort needs, we recommend trying it in-store or pairing with a different universal silicone mouthpiece.
