Questions & Answers

Larry C : What is the total weight of this suit? Can just the shirt be bought?Steve S : This is a fairly light shirt and this is just the shirt.MARIO S : It's quite a light weightand it protects and warms a little. You can perfectly wear the shirt alone. EnjoyWILLIAM S : I have a large and it weighs about 3/4 of a pound. It's pretty lightweight. Yes you can buy just the shirt only. Check out Leisure Pro's website for this product. There is a sizing chart to figure out what size to order. If you go to the specification tab for the product it should tell you the exact weight for the size that you need.SCOTT H : It's not a wetsuit and it's fairly light weight. A short sleeve, long sleeve, and other various versions can be purchased with shorts or pants. I personally own the short sleeve and a long sleeve with hood and shorts. I hope this answers your questions.GEORGE T : It's designed more a rash guard shirt or tone layered under your wet suit. I found it to be cumbersome to get on and off and ended up going to a 2 mil neoprene vest.C MICHAEL C : The product you are looking at is the shirt only. It weighs less than a pound dry. I recently purchased a short sleeve shirt and a couple other Lava Core products. I love their products but they all run small. I'd suggest a size or two larger for the shirt. It works great wet alone or as a base layer in dry suit. I'm just a consumer but love their products.ROBERT M : It is like a really heavy lycra. It is just a shirt I bought for swimming in public. Is good if you are swimming around coral and has good abrasion resistance. I got it because I have had multiple surgeries and don't want to scare kids or have to answer a lot of questions about it. It has no boyancy factor and fits snugly so swimming in it is better than using a t-shirt.
Steve K : How warm, or how much warmer is it in a wet suit with this on in addition?PETER J : Steve K, I have not worn the Lavacore under a wetsuit. A friend recommended the suit and he wore it, in lieu of as we were diving in the BVIs. I do believe it would add more warmth though.IVAN N : Well, warmer. It is quite thick and the inner side is fleece. When dry it is real warm, and wet not that much but still adds to total insulation.CHERYL P : Wish I could be more helpful. We haven't doubled up with wetsuit over the Lavacore, but a friend @ local dive shop says she uses hers layered with wet suit over it & it makes a big difference--she loves it. I love my Lavacore by itself. Its more comfortable than neoprene, as well as easier to get on & off..MARIO S : I've used in in Aruba, water about28 degrees centigrade, it's maybe a bid cooler than a 3 mm, however for me it was warm enough and much easier to put on and undo. Enjoy Mario
Steve H : What size chest does the medium fit? thanksGARY J : You would buy a Medium, if you had a chest size of 38 to 42 (according to the sizing chart). I have a chest size of 48, which is at the top end of the XL - so I purchased the XXL. It fits well for my intended use. If I was planning on using it as a core warmer, I would have tried the XL.EUGENE H : I bougth XXL and found it true to size but I'm 6-5 and 280#
Shopper : Why Did You Choose This?ROBERT H : I have the full suit from Lavacore and it's well made and warm in tropical water. I expect the same from this tee and it's neutrally buoyant.STEVEN L H : Sizes are off from their chart. The last two were too small.CAROLYN B : Wanted something for warm water diving that fits loosely under a BCD but does not "catch" bubbles and was a little thicker than just a rash guard.STEVEN L H : I like it.

Best rash guard ever

Best rash guard ever! I use it frequently. Local diving and traveling with it. I will purchase this again when I need another one. I have two already.

Sizes are WAY off

Nice stuff - but the sizing is WAY WAY WAY off. I ended up 3 sizes up from the first attempt. I'm larger than most at 5'10' 265 but still - I ended up ordering 3 times. Be sure you measure carefully first - then order at least 2 sizes up - I recommend 3 if you are doing active sports (I am a winter standup paddler). I had to order King1 from another vendor when I discovered on the size-chart hanging off the shirt that 4X wasn't the largest size (it was the largest on Leisure Pro site) - King1 says on the tag it is 290-320lbs and measurements way beyond mine (King2 is for taller/thinner not heavier btw). I tried a 2X - ok - I should have measured - by my measurements I was 3X and I decided on 4X so I could move/maybe wear lingers - I can get a 4X on, but can't really move. I might need 4x if I can drop to 235lbs but I'm not sure - I have large arms. Size King1 - is about right for me. I'm very stocky/very strong, a lot of my weight is in arms/legs and the top is not loose anywhere, even waistline. If you are larger than 265-275 you may not be able to use this product. Leiser Pro was great about returns - but I paid about half the total value in the 2 return shipping costs to get it right. Use a flat rate USPS box it's much cheaper than the one it comes in. After all that - I've used the top one time, out paddling in ambient about 50f and winds of 10 to 15 knots - it's great. Kept my torso warm and cozy I need to fall in a few times to really test it but I think it's just what I need. Erik In Alaska.

Nice weight, good fit, though a bit tight getting on over the head. Fits under my 5mm if needed for extra warmth.

Tight but effective

I ordered the 3xl size based on the measurements in the sizing chart. My measurements were between the 2xl and 3xl and I'm glad I went with the larger size. The shirt was very tight when I first put it on but was very comfortable in the water. I was snorkeling for a couple of hours and found that the shirt didn't impede my motion and was very effective as a rash guard and sun block. I was swimming in the BVI and wasn't chilled. You could use this as a wet suit alternative in the Caribbean. Highly recommended.

Kept me warm but it was difficult to get on and off.

Order larger than guidelines say. Runs small. I bit difficult to get over your head. I ordered two pieces instead of a one piece wetsuit. Due to the difficulty in getting on and off I would likely pick something you step into. Was great for warmth in the cold Galapagos Islands! Wore under a shortie provided by cruise.

Lavacore Mens Long Sleeve shirt.

Leisure Pro again provided excellent service and delivered a great product. Just dove with the Lavacore Mens' longsleeve shirt in Cayman Brac. Not one that gets cold this offered me as much protection as a 3 mil shorty. Love that it is fleece lined. I would highly recommend Leisure Pro and the Lavacore line of products. Note that I ordered a 3x size and normally would do 2x and it was snug but was the right fit. 6'1" and 240 lbs.

Sizing seems to run a size small...

I have a Lavacore hooded vest in a Large that fits fine, but when I wanted a long sleeve shirt I ended up having to go up to XL. I'm 6'2", 185 lbs, 42" chest and by the sizing chart a Large should fit (5'10" to 6'1", 210-240 lbs, 42-46" chest). I tried on a Large at my local shop but there was no way I was going to fit in it. They didn't have XL (5'11" to 6'2", 235-265 lbs, 44-48" chest per the chart) in stock so I ordered from Leisure Pro. Out of the package even it seemed small as it had little stretch trying to put it on. But on my first trip I found that once it was wet from a previous dive it has more stretch and went on/off much easier. It's definitely not loose, even wet, but I think XL is the right size for me.

Allergic to Neoprene

I am allergic to Neoprene and this was a very good option for me. It does not seem as thick as Neoprene in the 3mm range, and it is smaller than advertised, but it does it job and doesn't cause me to itch for 3-5 days after I wear it. It does seem to be solidly constructed.

Lavacore Women’s Long-sleeve Shirt

I love this shirt, very warm and neutrally bouyant. I can wear this layered or as a stand-alone. The only con I have found so far is the slow dry time, but that is not a big deal.

Even thought the Lavacore size chart showed I needed a large, I ordered the extra large based on previous reviews. When I tried it on it was at least 2 sizes too small!! Very disappointing, don't buy.

Ridiculous under sizing

Wish I could write a review based on use. Since most reviews pointed out we should buy a size bigger than indicated, I did. Unfortunately even TWO sizes larger that I should need based on the charts was too small, I had to return for a size THREE size larger. Now those are out of stock and I have nothing at all to take on my dive trip next week. Lovely.

TIghter than the size chart shows

I was impressed by the Lavacore shirt while on a liveaboard in Socorro, where 2 dive instructors were wearing them. They both highly recommended this high quality product, so of course, I ordered one. The older I get (and after 1500+ ocean dives), the less I want to be cold while diving. The product arrived quickly, and as described. My only negative observation is that despite me being well within/ at the low end of the LG size chart dimensions, the Lavacore Long sleeve LG shirt is quite tight. I can see where I might need assistance getting it off after a dive. I had originally ordered the ML size, and LeisurePro was great about refunding/ exchanging for a LG. I have decided to keep the LG size, and have a tight fit.

Mike P

I used the Lavacore shirt with Lavacore short pants as my base layer under a 2mm/3mm wetsuit while doing Cenote diving in Mexico late August 2017 and both worked great. I was concerned because I was told I'd need a 5mm for diving in a Cenote, but I was very comfortable with my Lavacore shirt/pants and 2mm/3mm wetsuit. I wore the Lavacore pants and shirt over my rash guard pants and shirt. I wear an XL rash guard, but I wanted the Lavacore shirt and pants to fit snug, so I ordered the Lavacore pants and shirt in a Large. It was snug, but I was able to put both on dry and take both off wet. I took the Lavacore shirt off between Cenote dives and was able to get the damp shirt back on wet.

Runs small

Well made product, fits very small, use the size chart to determine appropriate size. Warmer than a traditional wetsuit, both in and out of the water (on the boat trip back). Flexible enough to be easy to put on.

Lavacore in the Galapagos

The Lavacore top and bottoms were simple wonderful to use. My only advice is that they run small. I had to second day air a larger size before my trip to get it on time. I used a neoprene dry suite on my trip to to Galapagos which fit much closer then my cloth dry suite, so I was happy that the Lavacore fit snug to me body. Chad

Great for a little heat on a cold dive

Purchased the Lavacore short sleeve shirt for diving in Wisconsin all year long. Wanted something for under a 7mm wet suit to keep the heat in by my body. I already have Lavacore socks, which are fantastic. This shirt is great for that purpose. We do ice diving in the winter and this shirt helps a lot. Normal water temperature is 34 - 47 degrees. I ordered an XL and it was true to the fit and tight. I wanted it that way to remove unnecessary water movement. My only issue is when it is wet, removal is difficult unless you have your buddy help start peel it up.

Lavacore Short Sleeve Shirt

This stuff is great for cold water. I wore the short sleeve short for a quarry dive last week. Under a 7 mil wetsuit it was great. Bottom temp at 60 feet was 46 degrees. It does a terrific job. (Just order it a little big. The sizes run small.)

Lava Core

Love lavacore

By GREGORY H.

Great warmth with no bulk. Much better than a wetsuit.

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 shirt 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.

Shirt is DWR: Durable Water Repellant has flat seam construction throughout for stretch and comfort. Lavacore is neutrally buoyant so you won't need to add weight to your weight system compromising your weight comfort zone. Full gusset incorporated into the underarms offer exceptional arm movement and stretch and all seams are overlapped during flat-lock sewing to ensure maximum water integrity and strength. Lavacore provides SPF 50+ sun protection and is designed and developed with your guarantee of quality. Men's short sleeve shirt has a waist drawstring closure with barrel lock to prevent suit ride up when layering under exposure suit and is hypoallergenic. Shirt is available in multiple sizes.
