Rating: nice hood
Reviewer: Nancy B.  -  View all my reviews
Nice hood. Easy to don and doff. Fits well. Nice reflective strips on the back of the head - should make it easier for my dive buddy to see me. Havent used it yet but dive season here in the midwest is starting in a week or two - cant wait to get it (and me) wet.

Rating: The hood worked great!
Reviewer: Risa W.
The hood fits very well, fastens easily and kept me very warm. There is a very strange "flap" on the exterior that looks like a fault, but otherwise, it was a great purchase and at a great price. Thanks.

Rating: Great fit/ warm
Reviewer: David L.
Used this hood down to 50 degrees Fahrenheit. Could have gone colder. Great fit. I have a large Pinnacle wetsuit and the large hood fit great.

Questions and Answers for Pinnacle 7mm Merino Titanium Lined Zippered Diving Hood:

  • Peter:

    What is the difference between HD21UBK and HD22UBK?

    Bob  (Certified Scuba Instructor at

    Basically one is simply a newer model of the same hood. There are no differences other than aesthetic differences.

  • Jeff:

    Will this hood withstand deep dives (to 200ft)? Will the neoprene be ruined by the pressures or will it retain its thermal protection?

    Darrick  (Certified Scuba Instructor at

    Hello Jeff, yes this hood will work to 200''. The Merino lining with help reflect the heat back to your body.

  • Sarah:

    Hi, May I know where the zipper of the hood is located? Is it possible to find on without the zipper?

Available in 7mm and 5mm varieties, Merino Lined Hoods now feature gusseted zippers to aid in donning and doffing. They also Pinnacle’s patented neck sealing system, as well as all the features of Pinnacle’s standard hoods.

• Merino™ lined neoprene is 35% more thermally efficient than
traditional rubber
• Sealing system is drier and is even more effective at depth

• Sizes: XS, Small, Medium, Medium Large, Large, XL, and XXL.

Though Merino™ was virtually unknown to the diving industry 5 years ago, it has come to be known as a hallmark of excellence. Discerning divers who want the most innovative and most durable products seek out PINNACLE, and those who will settle only for the best of the best choose PINNACLE’s Merino™ lined products. This unique material is truly the best-performing way to line a suit ever devised, providing more warmth, comfort, and odor control than any other.

The key step to making any wetsuit perform to its ultimate potential is reducing water transfer. This process, whereby water from the diving environment enters and exits the wetsuit, allows cold water to enter the suit and lets bodywarmed water exit; thus chilling the diver, even in tropical waters. PINNACLE nearly eliminates water transfer by creating better barriers to keep cold water out, making more form-fitting products that prevent internal water movement, employing the renowned Merino™ lining system to enable body heat to warm internal water, and then making it extremely difficult for that warm water to escape.
