Rating: Happy with this product!
Reviewer: Linda W.  -  View all my reviews
I thought that the shirt might be a little tight, but I had lots of freedom in movement when snorkelling. Gave me that layer of warmth when I needed it and good protection from the sun.

Questions and Answers for LavaCore by Oceanic Trilaminate Polytherm Short Sleeve Mens Shirt:

  • Rick:

    what size, I am 6-6, 255 lb, 48-50 chest what is a king-1?

    Bill  (Certified Scuba Instructor at

    The size chart has been updated to include those sizes.

  • Katherine:

    I tried on the womwnes large and it fits except for the shoulder, that are too tight. Should I try a mens med?

    Darrick  (Certified Scuba Instructor at

    Hello Katherine, you would need to go with a size men large if you are looking to add a few inches to the shoulder. The men medium is an inch shorter in the chest area.

  • Katherine:

    Hi Derek, The womens large actually fits fine in the chest..a little loose, t is the shoulders and under arms that are tight. Do you really think I need a mens large?

    Darrick  (Certified Scuba Instructor at

    Hello Katherine, the men medium in the chest is a size 42" where as the women large is a 43" so you are going to lose 1" in the top part of the shirt. If this is ok then yes a men size medium will work for you.

  • Pam:

    How does this compare to a 3ml wetsuit for warmth while scuba diving?

    Bob  (Certified Scuba Instructor at

    LavaCore states their products offer the thermal properties similar to a 3mm neoprene suit without the buoyancy. When it comes to a shirt, though, keep in mind that by it being open at the bottom, water flushes through it constantly making it nearly impossible for the suit to do the job of keeping you warm. Your body creates the heat. The fabric is the insulator and the water, being the conductor of the heat is constantly flushing it away.

An all around multi-sport thermal garment offering protection against wind chill and surface splash coupled with the ultimate flexibility of movement that is required in the more extreme watersports.

Wind-proof middle layer provides anti-wind chill properties and ensures warmth in cold conditions
Water resistant outer layer facilitates fast water run-off and quick drying
Light weight and 4-way stretch makes Lavacore incredibly comfortable to wear
Breathable middle layer allows moisture to be drawn away from the body on the surface
Lavacore is neutrally buoyant
All seams are overlapped during flatlock sewing to decrease water flow
Full gusset incorporated into the underarm to offer exceptional arm movement and stretch
Anti-bacterial inner fleece minimizes odor and eliminates bacteria growth
Extended material on back to keep vests and shirts from riding up
SPF 30+ protection


Close to the skin, this soft internal fleece combined with high 4-way stretch produces the ultimate comfort / warmth / weight ratio, a true leader amongst artificial/man-made fabrics within the water sports industry. Wet or dry, hot or cold, Polytherm helps control your core temperature longer and when wet maintains neutral buoyancy, crucial to divers and any high activity watersports enthusiast.

Due to water weight being eliminated the garment becomes an ultra performance piece of equipment - essential to your body’s needs of maintaining a safe and secure temperature. Whether worn as a stand alone garment, under your wetsuit or even clothing, olytherm is guaranteed to keep you well insulated, flexible, lightweight and free from windchill.

Polytherm Tri-Laminate
Combining the outer shell and the inter PU layer, the fleece of Polytherm integrated ensures a very high heat and insulation rating, the PU film layer gives this combination added water resistance and high protection from windchill. Used in areas where extreme heat retention is required.

1) Ultraflex Durable Outer Protection +
This outer lycra layer is a 180g/sqm knitted nylon warp knit Tricot with water repellent treatment to ensure fast water run off and anti wind chill properties.

2) Waterproof/Breathable MIddleMembrane +
Layer is an impermeable Breathable Microporous high stretch PU Film which is wind proof and breathable allowing perspiration to be drawn away in hot conditions.

3) Insulative Thermal Inner Layer +
Fleece layer is a 240g/sqm 4 way stretch polyester fleece with elastane. It has Anti-Pill treatment as well as Anti-Microbial treatment to reduce odor and eliminate bacteria.

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.

Panel Design
The Lavacore range includes female and male specific cut and unique design.
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.
