Determining the Best Wetsuit for You

You've probably thought of wetsuits in the past as being unnecessary for your needs, and maybe even a little funny looking. However, wetsuits can be of great use to you, even if you're just learning how to dive, or you're an expert on the surf. Wetsuits have numerous advantages for swimmers to take advantage of, including:

  • Additional flotation
  • Reduced drag in the water
  • Extra warmth in colder waters

But there are tons of wetsuits out there and many different styles. How can you know which is the best for your needs? Read on.

How a Wetsuit Works

Before you determine which wetsuit you need, it is useful to understand how a wetsuit actually works. A wetsuit traps a thin layer of water between your body and the wetsuit material, letting your body warm the water to a comfortable temperature. The thicker your wetsuit, the longer and warmer your body will remain in the water. 

To keep your body warm and dry, many wetsuits are made with a material called neoprene. Neoprene is a synthetic, elastic rubber with excellent insulation properties. The thicker the neoprene in a wetsuit, the warmer you'll be in the water. The neoprene in a wetsuit traps the water between the suit and the skin while body heat warms the water, reducing heat loss in cold water. Buoyant and lightweight, neoprene can also be used as a protective cover because of its resistance to abrasive textures.

Thickness and Warmth

To determine how thick of a wetsuit you should buy, you will need to take into account the temperature of the water. If you plan to use a wetsuit on the beach in the middle of summer, your wetsuit will be much thinner than if you wanted to use it in the winter. Wetsuits aim to keep warmth in and cold water out. The colder the water, the thicker your wetsuit should be. 

Some wetsuits use air chambers on the outside of the suit to trap heat. Fused with a locking zipper, this mechanism blocks out water to prevent flushing.

Below is a chart to help you decide what style and thickness (mm) of wetsuit is right for your water climate.

  Water Temperature    Type of Wetsuit
  75+F   Rashguard
  74-64F   2mm Springsuit
  66-59F   2mm Long Sleeve Springsuit or 2-3mm Fullsuit 
  59-56F   2-3mm Fullsuit + Optional Booties
  55-50F   3-4mm Fullsuit + Booties
  50-44F   4-5mm Fullsuit + Booties + Hood
  43-F   5-6mm Fullsuit + Booties + Hood


Freedom of Movement

In the water, your movements shouldn't be restricted. A wetsuit that is too snug will make it hard to swim properly. Your wetsuit should fit comfortable against your skin, without restricting arm, leg or body movements, but snug enough that water can't easily get in. Each wetsuit manufacturer has their own standard sizing for wetsuits, which may vary between companies.


Each wetsuit has its own kind of seam, each with its own set of pluses and minuses:

  • Overlock Stitch: Found on the least expensive wetsuits, the overlock stitch sticks out of the neoprene, which can be uncomfortable. Although strong, this stitch leaves needle holes for water and wind to enter the wetsuit. 
  • Flat Lock Stitch: A completely flat stitch that goes through both sides of the neoprene shell. This does NOT provide a water tight seal.
  • Glued and Blind Stitched: This stitch is first glued together then threaded with a needle on the same side, not going all the way through. Continuous stretching and use over time may create small holes.
  • Liquid tape: Rubber used to seal the inside and outside of the stitching, creating a 100% waterproof seam.
  • Neoprene Tape: Most flexible seam tape. Can be used on the inside of the seams, creating the most flexible 100% waterproof seal.


The zippers on your wetsuit can vary as well, which determines how you get in and out of the suit itself:

  • Back Zip: Opens vertically down the back, making it easy to put on and take off your wetsuit. However, this type of zipper also reduces flexibility and can be stiff.
  • Chest Zip: Zips horizontally crosses the upper chest, providing more flexibility on the back of the suit. This kind of zipper keeps water flushing through the suit while swimming or surfing.
  • Zipper Free: Wetsuit is made of neoprene with flexible liners utilizing Velcro™ closures, keeping the cold water out and flexibility in.

Wetsuit Styles and Accessories

Now that you know what to look for when choosing your wetsuit, you are ready to pick the right one for you. However, there are many types out there. Choose the one that suits your needs!

  • Full Suit: One-piece suit that stretches from the top of your neck to your ankles. Also called a full-length suit. View: Men's Full SuitsWomen's Full Suits
  • Spring Suit: Either has full length legs and a short sleeve top or a full length top and short length legs. The type depends on your personal preference. View: Men's Spring SuitsWomen's Spring Suits
  • Dry Suit: Used for extremely cold water conditions. Dry suits are designed to keep as much waterb out as possible by using rubber seals around the neck, wrists and ankles. Some also use Velcro™-style straps around the wrists and ankles to provide an extra measure of sealing.
  • Three Quarter Suit: One-piece suit with short sleeves and legs that extend to the ankles.
  • Farmer John / Long John / Short John (Jane): One-piece suit which combines a vest top and either short or long legs. View: Men's Long JohnsWomen's Long Johns
  • Spring Suit: One-piece wetsuit with short legs and long or short sleeves.
  • Rashguard:  Not a suit itself, but can be layered under a wetsuit for extra warmth and to protect against chafing. Rashguards and looser fitting surf shirts block UV rays while under the sun. View: Men's RashguardsWomen's Rashguards
  • Hood: Used to keep your head warm and keep the wind out when in cold temperatures. Some wetsuits come with the hood attached or you can purchase the hood separately. View: Men's HoodsWomen's Hoods
  • Gloves: Keeps your fingers and hands warm in cold water. They come in different thickness levels and styles depending on your environment. View: Men's GlovesWomen's Gloves
  • Booties: Foot coverings to protect your feet in cold waters. They have two varieties: round-toe and split-toe. The split-toe, or two-toe, has a compartment for your big toe and another space for the rest of your toes. This adds more stability in the water, keeping your feet warm in colder climates and offered in different thickness levels. View: Men's BootiesWomen's Booties

I want to swim in an outdoor pool that is around 81-85 F but the air temperature is around 35-45 in the winter. My back and arms exposed makes my body a bit too cold. What do you recommend for a wetsuit? is there some other type of long sleeved high back swimsuit that would also work. I swim 100 25 yd lengths in an hour usually, so I move decently fast.

For thickness and warmth you will want to consider a 2/3 mm wetsuit. As for size you will want to compare your height and weight to the sizing charts provided. Sizing for each item will vary from brand to brand and often depend on the style and materials.

I have a 2mm 1/2 wet suit (short in arms and legs) that I plan to use for lake swimming for 65-70 degrees. I'm bald, and wondering if my head will feel the cold more than my extremities, in which case I should get a hood. Thanks for any advice.

Hi John!

We recommend the "IST 5MM Hood with Triple Glue". This has an extended bib to guarantee a seal underneath the collar of a wetsuit. It has different neoprene sections for the best possible combination of stretch and durability. The face seal is lined with smooth skin to eliminate water transfer and the jaw/ throat area is designed to stretch to accommodate variances between users, while the collar, head, and triple glued blind stitching is designed for maximum thermal protection and durability. The top panel is double layered to create a vent to allow air or water to escape the hood to prevent unwanted pressure or bubbling.

Hello Lucas!

When selecting a wetsuit you will want to decide whether you want a full sleeve or sleeveless and what thickness you prefer. As for sizing it is best to review the sizing chart for each wetsuit you are viewing. Sizing Charts are located just below the size selection and just above the add to cart button on each product page.

I want to swim in our apartment pool year 'round but it's only heated from May through October. I'm still cold even when the heat is on but I warm up after a few laps. What would you recommend for when they turn off the heat? I live on the SF Peninsula in an area where it's windy most evenings and the pool is in the shade by the time I get off work. I'm also 5'4 & 185# so I'm not sure about sizing either. Do they even make anything my size?!

Really missing swimming, I live in the Puget Sound/Seattle area, and it looks like the colder lakes and the Sound are my only options. I'm 5'6", weigh 115#, and get cold in an 83 degree pool. :-))) (No kidding.) I want a really warm and flexible wetsuit designed for swimmers. I also have a really testy back, and the full suits are SO difficult to get on and off that I often put my back out trying. Is there a warm option? (eg: top with balaclava hood & separate bottoms? A long-sleeved shortie with leg coverings?)
Thanks so much!

Im looking to purchase a suit for my daughter, she is 5'7" and 93 lbs, so far the suites either hike up her crotch area or they are super baggy on her. She uses it for surfing and sometimes swimming at the Oregon coast, waters are cold and she struggles to stay warm since she is very thin with no body fat.
Thank you

My husband is in need of a 100% waterproof garment that will completely keep his legs and feet absolutely free of any and all water. He needs this to clean our above ground swimming pool just at the beginning of our swimming season for Washington state, he would be wearing the suit for a few hours for several days. He will be getting inside pool to clean and scrub it by hand. He believes he would need a full wetsuit? The issue is: he is approx 5’ 2 1/2 - 5’3” tall and weighs 255 - 260 lbs. Do you have recommendations and in a size that would fit?
