Miflex Diving Hoses are a great way to save some weight on a normal set of diving regulators. You can get Miflex BCD hoses, Miflex Regulator hoses and now even Miflex HP Hoses for the contents gauge.
Please be aware though that the Miflex HP Hose is quite a lot narrower than a normal HP Hose so they will slip through a normal hose clip. If you do have a Miflex HP Hose then this is the Miflex hose retaining clip you need.
