Straps for your mask are a pretty important piece of kit, when you think about it! It keeps your mask on your face, and avoids any 'oh dear' moments such as your mask falling off underwater!
Why not take a moment to go and check your mask strap, as they are a consumable and do wear out. You could even grab a spare for the dive bag for those 'just incase' moments!
Available in clear or black silicone.
