Lavacore Long Sleeve Rash Vest




The LavaCore Long Sleeve Shirt can be used as a rash guard and as thermal underwear for SCUBA diving in colder waters.

Good fit, sizing chart is right for the Lavacore tops. Warmth factor is good.

Bought this thinking I would use it on my second dive, but found it so snug that I wear it on my first too. I am using it to dive in Tenerife, water temp 19C. It's under my semi-dry. Mine turned out to be a snug fit too, which is what you want, prove

I ordered this item for my husband to wear under his wetsuit whilst diving in the Red Sea in March as an extra layer of warmth. I already have the female version and love it. The outer layer of fabric keeps the wind off and the fleecy lining is war

I am no small person and ordered the Extra Large. The top arrived labelled Extra Large but to be hones it is VERY tight getting the top on. However, it may well be that this is how it is supposed to work as the last two dives have been in water tempe

1st dive trip using Lavacore to the Red Sea, used it under my wetsuit brilliant

Thought is was a very light, thin rash vest. Turned out to be very thick and heavy.

I am in the lower end of the size range for large and this is a tight comfortable fit but does not restrict movement. Replacement for older Lavacore LS and works fantastic under 5mm wetsuit as a thermal layer
