Lavacore is a technically advanced fabric, constructed and engineered exclusively for water sports requiring the ultimate in thermal control and superior comfort. Thermal and neutral buoyancy properties create the ideal garment - under a neoprene wetsuit for added insulation and warmth or as a stand-alone exposure protection garment. The unique design of Lavacore materials eliminates constriction and allows for extreme movement and flexibility while regulating your core warmth.

Lavacore shirts are made with an exclusive Polytherm Tri-Laminate. Ideal for use as a primary exposure suit in warmer waters or as a supplemental undergarment in colder waters. Windproof and breathable providing anti-wind chill properties while also drawing moisture away from the body on the surface, ensuring warmth in cold conditions. For the ultimate in warmth Lavacore's Merino Laminate lined garments are super soft yet durable. Moisture wicking and anti-bacterial, the Merino fleece inner minimizes odor and keeps you warm above and below the surface.

Lavaskin Poly-Fleece Technology: Engineered with a durable exterior layer bonded to a soft, fleece-like inner lining that traps a thin layer of air/water against the body to maintain core warmth.

Neutrally Buoyant: Material does not compress at depth or add positive surface buoyancy, eliminating the need to adjust ballast weights when worn under a wetsuit.

Anatomical Women’s Patterning: Tailored specifically for female body contours, ensuring a form-fitting seal that minimizes water flushing and bunching across the waist and shoulders.

UPF 50+ Sun & Wind Barrier: Acts as a complete solar radiation block on surface intervals while serving as a windproof shield against boat breezes and spray.

Flatlock Seam Construction: Durable, flat-stitched seams lay smooth against the skin to eliminate chafing during repetitive paddling, swimming, or long gear-wear sessions.

Versatile Multi-Layer Use: Functions as a standalone thermal top in warm tropical waters or as an undergarment thermal layer beneath wetsuits for added core protection.
