Worked just as expected. I have molded mouthpieces on all my regulator setups. It does ease jaw fatigue. At the surface, I can literally just open my mouth and breathe the ambient air while still keeping it in my mouth and ready.
Love this new iteration of the hydros pro. Super lightweight and pack really tight. Took it to the pool and it has excellent trim with only 4 lbs in the mini pockets. Got the air 2 version and it breathes well. The only thing I will be changing is the LP hose for the Air2. I will be replacing the one it came with with a 22.5” flex hose for lighter weight.
Overall this is the most comfortable BC I have used in a long time. Highly recommend this BC for divers of all skill levels.
Though Scubapro Reefhook w/ Stainless Steel Bolt Snap is well made and its compact size would make it easy for storage even in a pocket, I just feel it is a little on the smaller side.
