A well-fitting mask is key for comfortable snorkeling.
Place the mask on your face without using the strap, then gently inhale through your nose to check if it stays in place. There should be no gaps between the mask and your skin.
Next, adjust the strap so it is snug but not too tight. Make sure the seal around your nose and eyes fits properly, as any leaks can let water in and affect your experience.
A good fit keeps you comfortable and ensures a worry-free snorkeling adventure.
