Sizes do Run Small

I just wanted to let everyone know - when the other reviews state size's run small they aren't kidding. I'm a Large: always have been - Got the shirt: Returning it for X-Large.


Super Comfortable

By Jon

Very warm and comfortable. Great for wearing under a wetsuit for extra warmth.

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.

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 long sleeve shirt has thumb loops, 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.

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.

Lavacore in the Galapagos

By Chad A.

from Escondido, CA, US

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

Very warm and comfortable. Great for wearing under a wetsuit for extra warmth.


Warm, comfortable, and looks good

By Bazil

This is such an awesome product. Used it recently on a warm water trip to the phillipines, and we were doing 4am early morning departures for one of the sites. I wore this out on the 30m pre sunset boat trip, and it kept me warm with the sea spray. In the water, it was warmer than my 3/2 full suit and i paired the top with just a pair of board shorts. I felt really good on trim. Although i felt I had a bit of added bouyancy and was using the same weights as when i dived my 3/2 ss/ll suit. All in all excellent. When i first tried the top it was quite tight on the chest, but after a few times in the water it fit like a glove.


Lavacore is good

By smitty



Great Option for a warmer rashgard


I did 6 dives at various sites in the Western Caribbean in March of 2012. I wore the Lava Core top and swim shorts on every dive. Max depth 95 ft and no problems, i stayed warm and comfortable.


Sizing seems to run a size small...

By James H.

from Fort Worth, TX, US

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.


TIghter than the size chart shows


from St Petersburg, FL, US

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.


Really warm 1 mil suit top


from Elkhart, IN, US

Great product. Too small. Sizes run SMALL!!!! I would add 2 sizes to what the chart shows


Shirt runs very small in shoulder/ arms

By Papa

I normally wear an XL but I had to exchange for a 3XL to get the right fit. I feel like it is equal to 2mm of Neoprene.


Warm and versatile!

By Suzy

Lavacore is a great product and my dive buddies were envious of the two piece design. At first I thought the excessive length of the top would be a problem, but when I wore both pieces (top and bottom), the length allowed enough overlap that I didn't have a lot of water seeping in to my core. For warm water diving (as in Grand Cayman), I was fine with just the shirt on warmer days and used the pants one misty morning. Nice versatility to have that option. The lavacore products did not affect my buoyancy at all, so no change to weights was needed. One design issue for me was a single seam at the neck that chafed a bit, but it may just be my unit. A bit of tape over the seam end fixed the issue.


Sizing very poor

By Batman

no issues with service or delivery


Way too small!!


from Poquoson, VA, US

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

By Tom D.

from Houston, TX, US

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.


Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
Robert L  Research
GLENN B  I have a lavacore vest and it is super comfortable against the skin under a drysuit, perfect first layer for super cold diving above 50F it is my only undergarment in a dry suit.
MICHAEL M  Need it for warm water dives and night dives.
MARK M  I was recently on a live aboard to Socorro Island with 2 dive instructors who were wearing Lavacore shirts. They were highly impressed by the thermal protection and comfort. Enough of a recommendation for me.
John B  For warm water snorkeling to give more warmth, sun protection with the bonus of neutral bouyancy
JOSHUA S  I use it primarily for diving in Belize, but also as an undergarment under my 5mm when diving deep our extended dive time.
MICHAEL D  Wanted light weight exposure protection with more warmth than a rash guard.
Shopper  Is it best to get one size smaller than your shirt size for a better, snugger fit? I tend to get cold when diving in cool water even with my 5mm wet suit. thank you in advance for your time and help.
RONALD H  No, one size smaller will be too small. They are already undersize in my opinion. It is a struggle to get out of when wet. I wish I had purchased zippered version.
MICHAEL D  I use my normal shirt size. It fits very snug. Have not tried it under a thicker wetsuit. I use it as a light weight, warm weather suit.
BOB G  Lavacore sizing is odd. Maybe because the started in Australia? My dive buddies and I have all found that their shirts run small. Do not order a size smaller than your normal shirt size. If you do, the Lavacore will be uncomfortably tight. I strongly recommend you order one, or even two, sizes larger than you normally would. Don't be surprised if the sleeves are too long.
DAMARYS P  It is for the most part a true fit. If anything it's a little snug.
GARY P  No, they are sized correctly and have a lot of stretch. Get your regular size. Smaller would make it too snug
DALE C  That's a tough one as I remember the sleeves being too tight when the body fit, so I returned the long sleeve for the short, especially to wear under another suit. The material isn't as stretchy as neoprene, so you might think of that so you don't feel restricted wearing it. the associated measurement charts were pretty close, except for the sleeve thing. Hope that helps. Good diving to you.
KIRILL L  I would say, get your correct size or even a bigger size, it's very snag fit.
Joe S  LavaCore is supposed to be true to size, however in some cases it may fit a little small. Lavacore is the equivalent to a 1.5 - 2mm neoprene and neutrally buoyant. It stays a little warmer when layered beneath a wetsuit. It does dry fairly quick except the lower part of the garments where the water drains. After about half hour, just wring it out and it should dry fairly quick.
PAUL P  I wouldn't. I had the same concern but am happy with the snugness. I am 6 feet tall, 200 lbs and wear a large.
JEFF H  Not unless u wear regular clothes large. Pretty true to size. FYI, I don't find lava core to be warmer than reg neoprene. Maybe equivalent to 2 or 2.5 mm... Also, dries ok except lowest hanging part of garment stays damp a long time, so you feel like you are aways putting on damp suit. Don't use my lavacore as much as I hoped. I dive in a 3 or 5 mm in warm water a lot (long dives, 3-5x a day) and sometimes I'll throw on a 5 mm ore for xtra warmth, even ith the 5 mm full suit. Hope this helps.
SHAWN N  I found the Lavacore clothing to run small. You might want to purchase the shirt in your regular size.
Shopper  My stats are: weight: 67 kg height: 192 cm waist: 31 inches chest size: 93.5 cm May I know what size fits me? Thanks, Zacch
KIRILL L  I think you should try size M first (I'm wider and I'm on the edge between M and L). However It might feel too small as it has very weird cut in shoulders. Note that size L has the same feeling :)
JEFF H  You vs me (I hope I got conversions right) weight 147.7 lbs vs 144 lbs height 6'3" vs 5' 8" waist 31 vs 32 chest 37 vs 40 I bought the medium. And the medium shorts. Love them both. The shorts will fit you. It sounds like you are tall and thin. I am afraid the medium might be too short in body and sleeves; don't know if the large will be too big in waist and chest. Hope this helps but sorry I can't be of more assistance. So...I love the product. Remember Leisure Pro's policy: You have 60 days from the date of invoice to return the merchandise for full refund on your credit card. So I'd order one and see; if you have a trip coming up order both and return the one that doesn't work! See you underwater!
JAMES A  Can you convert that to non metric lol
Fabio N  Yes, you'll be fine!
