Very warm and comfortable hood. While only 5mm thick it feels like 7mm. I really like the fact it has the zipper in the back to allow for easier on and off.

Questions and Answers for Pinnacle 5mm Merino Titanium Lined Zippered Diving Hood:

  • Wade:

    Not sure what size I should get. I measure around my forehead at 24" Im 510" and 270# Pinnacle has a hood sizing chart that says I should get a Large, your chart says I should get an XL. I plan to use this hood with the Pinnacle Tempo 7mm suit. What do you suggest?

    I would recommend size XLarge based on those measurements.


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.

In order to prevent water entry and egress, PINNACLE employs the latest technology in sealing systems. Features like honeycomb o-ring wrist seals, Orcaskin™ forearm gussets, smoothskin chimney seals in the ankles, roll-neck collars with smoothskin sealing surfaces, smoothskin-to-smoothskin sealing surfaces on 10mm spine pads, and the innovative Pinnacle Defense System (P.D.S.) combine in PINNACLE suits to create a significantly better water barrier than in other brands. These sealing systems work as checkpoints, neither allowing water in the suit nor out.

The second step, having a more form-fitting suit, is achieved by offering divers more choices in sizes. PINNACLE offers as many as 17 male, 12 female and 4 children’s sizes in wetsuits, as well as more sizes of boots, gloves, and hoods than most other manufacturers.
PINNACLE has the ability to customize suits to some extent to fit people with more challenging shapes, but with up to 33 stock sizes, one is sure to fit almost any diver perfectly; and a tighter, better-fitting suit leaves less room for water to move, which keeps the diver warmer.

The magic of Merino™ occurs between these steps, after a small, tightly-controlled amount of water is allowed to enter the suit, and before it (by this time warmed by a diver’s body heat) tries to escape.
