Question Hi Im 6'1", 170lbs, 33 waist... surfing in socal... Is the XL suit best? (I wear medium to large shirts)
Answer We suggest size Large but please provide other measurements for accurate sizing.

Question Hi-

I'm thinking of getting a new wetsuit.

Your answers say that the suits fit "tight" and to buy one size UP if in between. I'm 6 feet, 46inch chest with large thighs/bum.

If I get larger(3XL) then I'm afraid it will be way too long.

Is it just the IST suits that run smallish or all the wetsuits??.


Answer It might be a bit lengthy but the material is stretchy; the IST suits run true to size.

Question I'm 5'2", 140lbs. Waist 31-32". What size would be best for me?
Answer We will recommend you to try the size S, but it may not be perfect fit.

Question I am trying to find a suitable wetsuit for someone who is difficult to fit. He is 5'2" tall, 33" chest, 30" waist, and 35" hips. If it is long in the sleeves and legs, I can probably get it adjusted, but I wouldn't want it too long in the body. We need a flexible suit, suitable for warmer temperatures. Would this suit be O.K, or is there another one you could suggest? What size should we get?
Answer We will recommend you to give the size small a try.

Question I am 5'5" tall, weigh about 180 lbs. My waist is 40", my inseam is 27" and my chest is 44". I live in Southern California, where the water temperature is between 55 and 70 degrees. Do you have a full jumpsuit that will work for me?
Answer We will actually recommend you to get a 3mm-5mm wetsuit, according to the temperature you provided.
For this 2.5mm wetsuit, we will recommend you to get the size XL, but it may not be perfect fit. It may be a bit too long.

Question I'm 5'6", fairly muscular, 165 pounds, 30" inseam, 33 waist. I'm worried about the inseam on the large, I have a medium Body Glove, spring suit, shortie, its okay, a little tight in the chest, but I have used it in triathlons with no problems, except the struggle to get out of! I want to use this suit for tri's, and SUP on cooler days. Would you recommend a large? or stick with the medium?


Answer Would you please provide us your chest and hip measurement?
So we can give you a more accurate recommendation.

Question Will this suit work in Alaska in water temps 45-55 degrees.Basically using for dip-netting in waist to chest depths.
Answer It's too thin. 7mm will work.
Here is a link for you to pick the right wetsuit with right temperature:http://seavenger.com/wetsuits-c-37.html#wetsuitfinder

Question i am 5'11" / 220# my chest is ( 48 - 49" )
waist is ( 36" ) i have fairly large arms & legs.
i am thinking that a 2x would fit but what do you think?

Answer Yes, you can try size 2XL.

Question 1) Advice rather than question (re: recent purchase of a "L" size, received safely/securely; used one time presently for "sailing," surface only); I'm about 5'6" tall, a swimmer, of about 180 pounds, muscular; received in May 2013.
2) The "L" fit tight, a "M" would have been way too small; I could have bought an "XL" without difficulty, perhaps better?
3) It's a "good suit," never wet at this time.
4) Thank you.

Answer If it is too tight and uncomfortable, we suggest you to go for the XL.

Question Hi. I am an odd size. 37 inch chest, 34 waist, 20 inch thighs, 13 inch biceps, 150 pounds, 5 feet 2 inch tall. I wear a men's medium shirt. What size suit would you recommend for me? I would be using it in temperate gulf waters. I like this suit. Thank-you for your help.
Answer We would recommend you to get the size S, but it may not be perfectly fit.

Question I am 6'1" 40-42 waist 230 broad shoulder. skinny leg and arms 17 1/2 neck what size suit
Answer According to the information you provided us, we would recommend you to get the 2XL. However, please provide us your chest measurement, so we can give you a more accurate recommendation.

Question i am 5'10
weigh 160
waist 32
wat size do i need

Answer We will recommend you to get the size M.

Question I noticed you posted a refund. I thought I would receive store credit. You refunded the credit card I used? Thanks, I want to reorder with the correct size.

Please sign in your account and you will see the credit in there.

Question Height 6'1"
Weight 175
Chest 42"
Waist 32"
Inseam 33"
Hips 40"
Likely water temp 68-70 degrees. Will be kiteboarding and would like excellent arm mobility. I was thinking about a Farmer John style. Do you have a size and style recommendation? Also, I'm on a tight budget.

Answer From the measurement you provided, I would suggest a size L. Also we would recommend this suit here.
This is a 1MM suit, but with glide skin inside, so will keep you warm as a 2mm or 3mm. Also since its a 1MM, this suit comes with great maneuverability.

Question Is This A Good Triathlon Wetsuit?
Answer Depending on the water temp, usually we recommend shorty more than full suit for triathlon, just because shorty have a better maneuverability. Here is a link to the shorty we would recommend.

Question i'm 5-10; weigh 220, weist 40,what size would i wear?
Answer Suggested size: XL
following link you may see the caculator as:

Question Hi,

I am about 5'11, weigh about 185lbs, chest size 44', waist size 33inches. I bought a wetsuit (from another manufacture) that was XL and a bit snug. I would prefer to be more comfortable but am afraid to buy the XXL. Can you provide a suggestion Thx

Answer The suggested size XL should be the best fit for you.

Question im 6'4" 155 lbs tall and lanky..please help lol
what size should i get?

Answer XL might be the best for you but might still be to big.

Question Hi, my husband is 6'1'' and the rest of his measurements all fall in line with the large. Would you recommend the large or XL (for the length) for him. Thank you
Answer If his measurements are all exactly in line with L, and he is 6'1" we recommend XL since these suits are cut very tight.

Question My son is 5' 10" 125 lbs. small chest. Works in an indoor pool teaching kids to swim. Says he's cold during the 2 to 3 hours he is in water. It's in NY and I'm assuming it's unheated. Please recomend mm suit and size.
Answer This suit that you are looking at is definitely a good suit for indoor swimming, but I would ask for the water temperature first, if the water is not that cold, i would suggest a shorty instead of the full suit, better maneuverability. And as for the sizing, please provide us with the measurement of hes chest, waist, and hip measurement. That will help us to get you the most accurate sizing. Thanks

Question I ordered a diving suite in women size 15 I could fix the suit but, the arms were a little to tight. I was considering ordering the mans suit in a size XXL. I wear a size 16 and my weight is 215 lbs I am 5'5" and my bust is 44DD. Do you think that I maybe able to fit this mens XXL?
Answer This wetsuit may fit you, although it is made for taller men, and anatomically cut. Without your other dimensions such as waist and hip we cannot say for sure. Check the size chart under the product description. However, if the size 15 fit, it may work for those dimensions.

Question I want to paddleboard on a lake in the fall months (outside temps about 55 to 60) in CT.) I hardly ever fall in the water but don't want to be cold while I'm riding.
Answer The wetsuit you reference is a good choice. If you want even more mobility, plus the warmth of Metalite coated neoprene, you might want to consider this 1mm full suit from Tilos, an excellent manufacturer.

Question I want to buy this for my dad who is 5'7 and weighs about 135 lbs. He wears size medium shirts and has 30' waist. I want to get this for him so he can boogie board and play in the Pacific Ocean. Will this be a good suit for him and if so what size? Thanks.
Answer This 2.5mm suit should be fine for California Pacific Ocean most months, except maybe the winter. We would recommend a size M for him.

Question Is this suit good for triatholon swim event section?
Answer http://seavenger.com/1mm-titanium-lined-glide-skin-jumpsuit-men-p-1511.html
The suit you reference can work for a triathlon swim event, depending on water temperatures and swim distance. Another choice might be this 1mm titanium lined suit which gives you warmth in addition to more flexibility.

Question Hey there. I'm 6'6" and am a tree. I'll be using the suit during surfing. I weigh 156 32"waist and a thin chest. Is there a size you think would work? I'd assume the 6'6 version is too large.
Answer Unfortunately, we believe your dimensions will not work for any of our off-the-rack wetsuits; the larger sizes, height-wise, are for much heavier individuals.

Question would this suit be ok for surfing
Answer Yes, this suit will be very good for surfing, especially in California.

Question i am 5'9 155lbs waist size 32. chest about 38-39. i will be kayaking in the california ocean. what size and what mm do you recommend?
Answer http://seavenger.com/1mm-metalite-full-male-p-1181.html

We recommend a size M. The suit you reference is a good choice especially for the price. These 1mm suits are also excellent, and would give you much more flexibility. Depending on what time of year you are kayaking, they're also a very good choice.


Answer You do not specify how tall you are, but in all probability the XL will be ok since there is not a huge length difference and the extra room in arms and legs will be there.

Question I notice that you don't carry MT sizes. What would you suggest for someone like me that doesn't really fit your size chart? (6'0"; 165lbs.; skinny chest) Also, any combo deals with a women's version of this?


Answer These suits are cut on the small side, so a size L should fit you. Yes, we have the same combo deal for the women's version.

Question I will be snorkeling in spring water and the ocean with temperatures @ 72 degrees. I am 6'3", 220lbs.38" waist what size should I buy.
Answer You do not give your other dimensions such as chest and hips, but it sounds like you would take a 3XL which we do not have in this suit.
We do have it this suit:

Or, you may want to consider a shorty such as this one:
http://seavenger.com/3mm-stylish-tropical-shorty-blue-mens-p-315.html 3XL

Answer This is a terrific wetsuit, as long as the water isn't too cold. I definitely recommend it. He should get size M, although I would check his chest size as well. If his chest exceeds 39 inches, you might want to look at a large size.

Additional comments I have used this suit a few times and did a triathlon in it on Sunday, which was my intended purpose for it. It performed better than my expectations! For those who are getting into triathlons you will not be disappointed by this suit, comfortable, superb range of motion, I never felt restricted anywhere, for $58 can you say deal? You can go out and spend @$200 for a Zoot if you like, but why? I do want to have the sleeves and inseams shortened, just to make it easier to slough off, 4" on the sleeves and 3" on the legs.

This is an awesome suit for the money. I usually take a medium and opted for the large because it was described "as a tight fit" I'm 5'6" 160 lbs, with a 42 chest and 33 waist, 39" in the hips. I was worried the inseam and arm lenght, I have a 30" inseam, and long arms for a short guy. The suit is tight, but once on felt great, the inseam and arm lenghts are acceptable, although 1/2" shorter on each would be my preference. I was impressed by the high quality at a very low price.

This jumpsuit is make out of great quality material, tailoring and badging, but is is small compared to other neoprene suits in the same size classification: XL. I had bought an O'Brien Zen size L, and it was too small to close the back, even though I am just under 200lbs and just shy of 6', and so I bought one IST size XL and it was too small, needing help to close the back, and so I bought two more, size XXL, which aren't received yet.

I think the template for the jumpsuits needs a little bit of relaxing to suit the size classification.
