Rating: Nice Warmth with Neutral Buoyancy
Reviewer: Paul M.  -  View all my reviews
Wore my new LavaCore dive vest for some recent deeper dives. Being a vest style, it was fairly easy to put on. It fit just fine under my 5-mil wetsuit without bunching or adding bulkiness. During the dive, I could tell a nice difference in warmth as the vest helped keep my core warmed. I had made 10 dives in the 3 days prior to this, so had a basis for comparison to tell that the vest was doing its job. Also, during the surface interval and on the 45-minute trip back to the dock, the vest kept me warmer. Especially for quick, easy-to-put-on core warmth, this LavaCore vest was a great option.

Questions and Answers for LavaCore by Oceanic Trilaminate Polytherm Mens Dive Vest:

  • Mike:

    Looking for a snorkelling flotation device to help me stay buoyant since Im a poor swimmer. Had a waist line device in Mauii which helped. Would this type work better?

    Darrick  (Certified Scuba Instructor at

    Hello Mike, no this vest would not help you float at all. If you are looking for something that would add buoyancy to you while in the water take a look at are shorty line of suits:, also when you are sizing a wet suit or dive skin the two most important measurements are your chest/bust and waist. Height is a secondary measurement and weight is the last measurement you would take into account.

  • Anna:

    Hi - I want to order the LavaCore 2x vest for women but when I try to place the order, it doesnt differentiate between mens and womens sizes. How do I make sure I get a womens version in 2x? Thanks, Anna

    Aaron  (Certified Scuba Instructor at

    Hi Anna, On the drop down box select Trilaminate Polytherm Dive Vest 2XLarge (19-20). All the women’s sizing have a pair of numbers after the size.

  • Charles:

    I am 5 8 male swimmer and weigh about 140. I think that the Lavacore vests and tops may be comfortable & flexible enough for swimming. If so, what size should I consider in the Lavacore products?

    Hello Charles, when you are sizing a wetsuit or dive skin. The two most important measurements are going to be your chest/bust and waist. Height is a secondary measurement and weight is the last measurement you take into account.

Seam Construction
All of the Lavacore seams are overlapped during flatlock sewing to ensure maximum water integrity and reduced waterflow through the seams. Maximum heat retention is therefore achieved when worn in colder water conditions. See diagram. To ensure maximum integrity and longevity of your Lavacore garment the seam cross-overs on the inside of the suit are locked under the threads of the adjoining seam. The seam construction being doubled and flat-locked allows for maximum stretch out of the four way stretch fabric technology without compromising at seam edges.

Lycra panels with contemporary lines and graphics are incorporated into all garments.
Full Under the Arm Gusset. This ensures there is no rub or irritation on the sensitive under side of the arms and side of the body. It also reduces restricted movement considerably and allows for extra reach without seam strain and damage.
