Keep in mind that some factors other than water temperature could affect the wetsuit thickness or type of scuba diving wetsuit needed.
Tolerance for Cold:
A thicker or thinner wetsuit may be required or desired as everyone’s tolerance for the cold varies. If you are someone that tends to feel cold, err on the side of going with a thicker wetsuit. Otherwise, using the wetsuit thickness table should be a very good place to selecting the right wetsuit style and thickness.
Performance Expectations:
Something you will have to take into account is the demand for high performance. The less wetsuit (meaning thinner and less coverage) worn will translate to high performance. If performance is at the top of your wetsuit requirement list, you may be inclined to buy a slightly thinner wetsuit or go with reduced coverage as applicable. Alternatively, if budget can accommodate, a higher-end wetsuit can provide you with appropriate insulation and very high performance.
This now leads us to types of wetsuit products!
Lycra Rash Guards, Poly Fleece, Baselayers, etc.:
Rashguards and baselayers are primarily worn under wetsuits or alone, as sun and/or abrasion protection. These items do not provide thermal protection when worn alone, although baselayers do add some warmth, so they are only appropriate for water that is typically 75F+.
Springsuits, Short Johns, Short Janes, Tops & Jackets, and Bottoms:
These items provide wetsuit coverage to areas of the body. When a little insulation is needed and water temps are in the high 60’s, any springsuit, short john (or jane), top or bottom would be perfect. They also work well in heated swimming pools that just aren’t quite heated enough!
Long Johns & Long Janes:
Johns (men’s) and janes (women’s) are essentially sleeveless fullsuits. This style of suit is popular in layering applications, like SCUBA and kayaking. Johns & janes are also a popular style in triathlon/swimming style wetsuits, as this cut allows for full range of motion in the arms and shoulders.
Fullsuits or Full Wetsuits:
Fullsuits come in a variety of thicknesses for all water temperature conditions. In most cases, the thickness will be described with two numbers, such as 3/2mm. This means the majority of the suit is made of 3mm neoprene (wetsuit material) and the flex points 2mm. Manufacturers do this to enhance the comfort and flexibility of the suit.
We also offer SCUBA Combos so you can mix and match your scuba diving wetsuit!
From here you should be well on your way to choosing the right scuba diving wetsuit for your next dive. If you need some more help, we’ve got you covered! Give us a call, email (service@wetsuitwearhouse.com), or live chat!

Im a large OZZY bloke, 6″3 and 189kg (416 pound) dived all my life but its impossible to dive in the colder months due to never having a big enough wet suit last one i owned was 20 years ago and it was 3xl, im preying that you can help me
Hey Adam,
What is your chest measurement? From the sounds of it on your height and weight, you may need to consider a custom size wetsuit. Let me know your chest measurement and I’ll help! Thanks!
I rented a Henderson 3MM women’s full suit that fit well. I believe it was a size 10. Can you tell me the measurements that
would correspond to this suit size? My height is 5′-4″. Do you make suits for people that are not as tall?
Hi Laurie,
If you’re interested in a Henderson suit, their size 10 measurements are as follows:
Chest: 35 to 37 inches
Height: 5’5 to 5’8
Waist: 30 to 32 inches
Hips: 38 to 40 inches
I hope that helps you! As far as suits for petite heights, some brands do offer Short sizes which would be perfect for you. Feel free to let us know if you need additional help or information!
Are any brands tailored better for skinny people? I am 5-9, 135 pounds, 36″ chest, 28″ waist. I had an old O’Neill 3mm size men’s small that was super tight in the arms and legs but allowed me to carry around a gallon of water sloshing around the waist – hoping to find something more form fitting. Thanks!
Hey Dan,
Honestly, you should check out HyperFlex men’s full wetsuits. We have a great selection of size XS, which would fit your measurements. Check it all out here: https://www.wetsuitwearhouse.com/wetsuits/category/hyperflex-wetsuits.html
I am looking to find a manufacturer that make wetsuits for tall women. I am 6’2 and have curves (typical female 36/28/42). When I dove before, they just put me in a men’s…let’s just say, that was a disaster.
Is there anywhere I can buy off the shelf, or will I need to get it custom made?
Thanks for the help!
Hi Amy!
The tallest size we have for a diving suit is the Henderson 12T, which has a height range up to 6’0″. That may be worth a try – the sleeves and legs may be just a hair short, which should not be a problem. Here’s our selection of the Henderson women’s diving wetsuits in a size 12T: https://www.wetsuitwearhouse.com/wetsuits/category/henderson-wetsuits.html
Let us know if you have any more questions or concerns. We’re happy to help. Thank you!!
