When we set out to create Hawaii’s best spearfishing and freediving suit, we held nothing back. We chose the very best eco-friendly Yamamoto #39 neoprene because of it’s excellent performance characteristics and assembled our suit with bombproof and extremely durable glue-over-stitch bonding.  When you put on a WAIHANA Goliath Grouper Wetsuit, you will feel the quality immediately, while brilliant additions like an integrated distress whistle located on the shoulder will keep you feeling safe all day.  Our titanium dioxide lining makes it a breeze to slip into the suit while underway, and with thick screen printing, you won’t go sliding around above deck.  Buy Local.  By Locals.  WAIHANA.

The Goliath Grouper, or itajara (Epinephelus itajara), also known as “jewfish”, is a large saltwater fish of the grouper family found primarily in shallow tropical waters among coral and artificial reefs at depths from 5 to 50 m (16 to 164 ft). Its range includes the Florida Keys in the US, the Bahamas, most of the Caribbean and most of the Brazilian coast. On some occasions, it is caught off the coasts of the US states of New England off Maine and Massachusetts. In the eastern Atlantic Ocean, it occurs from the Congo to Senegal. [wikipedia]

    I’ve had my Goliath Grouper 3.5mm wetsuit for a little over two months now and I can honestly say after wearing it twice a week, it still looks new and keeps me warm and comfortable. I love that you guys use Yamamoto Japenese neoprene and incorporate tons of small yet profound features that make the suit extra durable, and keep me safe! The whistle is brilliant and well within reach for when you need to call over the boat man. Well done! Can’t wait to see what you guys come up with next!

    By far the most comfortable, durable, stylish, and warm dive suit i’ve ever worn. The attention to detail, form fitting material and design, makes me feel so much more relaxed and at ease while holding my breath under water. The Goliath Grouper suit is next level!!

    The Goliath Grouper Wetsuit was perfectly designed for the modern day waterman – the moment I put on the gear I knew Waihana thought of everything. Not only does this wetsuit include functional elements such as an emergency whistle, the form factor is also aethically pleasing and comfortable. In my home waters of Hawaii, the 3.5mm wetsuit is the perfect thickness , enabling me to stay in the water all day if needed. The craftsmanship of this wetsuit far surpasses any other wetsuit I’ve used in the past.

    I dive very often, and put all my gear to the test. I’ve been wearing the Goliath Grouper wetsuit for the past few months and I absolutely love it. The Yamamoto 39 3.5mm material in combination with the quality in stitching and glue make for a “TOP OF THE LINE” product.
    The main things I look for in a wetsuit are; a proper fit, comfort, durability, style, effectiveness. Wai’hana all those qualities and even incorporated safety into the mix with the S.O.S. whistle on the right shoulder of the suit.

    Quality isn’t a mistake, it’s intentional. The minute I dawn a Waihana Wetsuit, I can immediately feel how comfortable and anatomically correct the suit fits. The first thoughts that come to mind are, “the comfort will tremendously improve my performance in competition and training.” There are so many features that go unnoticed to the common eye. The integrated emergency whistle (color orange is key), the SOS Morris Code, high waist trousers, and the unique fish scale pattern that make you feel like some sort of new amphibious creature while I’m out there hunting and stalking fish..absolutely thrilled I own a Waihana Suit and would recommend it to everyone a 100 times over and over again!! 5 STARS!!!!!!!

    I have worn many wetsuits over my 17 years of diving. This wetsuit tops them all, it is the most comfortable and well thought out wetsuit I have ever worn. Not to mention one of the coolest camouflage patterns out there. This wetsuit is sure to make you comfortable and keep you warm in the water and make your dive buddy jealous he doesn’t own a Waihana. Thanks for a great product guys!

    speaking from the point of view of someone who has owned several wetsuits before this one-I can honestly say no other suit comes close to the quality comfort and attention to detail that Waihana wetsuits deliver. the gold titanium-lined interior offer sustained bodyheat while underwater; as well as a stretchy bounciness the fabric allows you for manueverability. the stitching and glue have been well researched and designed for rough hawaiian shoredives as well. I am so stoked and cant wait to see what Waihana has in store for future designs! 10 out of 10 fosho

    Waihana sets the bar high when it comes to providing quality wetsuits. The durability outperforms any wetsuit I had in the past. The added safety feature (SOS whistle), reinforced glued stitching, 24k gold lining and unique fish scale pattern are just some of the added features that makes this suit remarkable. These suits are tested and used by professional waterman and are made to outperform. Perfectly designed and crafted, this suit helps me perform at my best…If there’s an award for wetsuit of the year…the Goliath Grouper would be it!

    As a Spearfishing charter business owner I’ve used a lot of wetsuits over the years. I’m in the water 5 days a week and I need a workhorse of a wetsuit. I’ve always valued durability and value over aesthetics, now I don’t have to compromise on either. The Goliath Grouper suit by Waihana is the best wetsuit on the market today. Blending timeless style with the form and function required to get the job done day after day. My favorite feature is the 24k gold Titainium Dioxide (AKA Gold Dust) coating that keeps my suit from getting funky and allowing mold to eventually set in. Thoughtfully and expertly tailored with an ergonomic fit, the suit feels at one with your body, basically like a super hero suit.
