Product Information

The Lavacore Men's Short Sleeve Top is a three-layer thermal rash guard built for water sports that demand close-fitting warmth, worn as a stand-alone garment or layered under a wetsuit or clothing. It combines a water-repellent outer shell, a windproof breathable middle layer, and a moisture-wicking inner fleece, and it carries a UPF 50+ rating with neutrally buoyant construction.

Who it is for

This top is built for water sports participants who want to control core body temperature in wet or dry, hot or cold conditions, whether worn as a stand-alone rash guard or layered underneath a wetsuit or clothing.

Key details

Outer layer: 180 g/sqm knitted knylon wrap knit tricot with water-repellent treatment for fast water runoff and wind-chill resistance.
Middle layer: microporous, high-stretch PU film that is windproof and breathable, drawing perspiration away in hot conditions.
Inner layer: 240 g/sqm 4-way stretch polyester fleece with elastane, treated for anti-pill performance and anti-microbial odor control.
UPF 50+ UV protection and neutrally buoyant construction.
Flatlock seams overlapped during sewing, a full underarm gusset, and extended back material to keep the shirt from riding up.

Great purchase and "Like New" as advertized.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.
