Turn Up the Heat: 6 Cold Water Wetsuits to Keep You Warm

Turn Up the Heat: 6 Cold Water Wetsuits to Keep You Warm

Between surfing, paddleboarding, water skiing, swimming, snorkeling and diving, watersports enthusiasts spend a lot of time in, on and around the water.

That's all great when the weather's warm and sunny. But what's a diehard wakeboarder or kayaker to do when the weather takes a dip? Invest in a cold water wetsuit, of course!

A cold water wetsuit is an excellent way to extend your warm-weather fun into the fall (or even later depending upon your latitude and longitude).

What is a cold water wetsuit, you ask? Read on to get the low down.

How Do Cold Water Wetsuits Keep You Warm?

Cold water wetsuits, just like regular wetsuits, are made out of neoprene, which is basically a wearable piece of insulation. Constructed of small closed air-filled cells, this flexible and stretchy fabric traps a thin layer of water next to your skin.

This water is then warmed by your body heat, thereby keeping you warm and toasty in the water. The thicker the neoprene, the warmer you'll be.

Neoprene ranges from 0.5 to 5+ millimeter in thickness, so you'll want a higher millimeter rating for the ultimate warmth.

Types of Cold Water Wetsuits

Depending on the temperature (and your tolerance level), you have several wetsuit versions to choose from.
  • Full Wetsuit: Full wetsuits cover the entire body from arms to legs and usually with a high neckline. This is a good choice if there's any chance of getting immersed. It's even great for kayaking.
  • Shorty Wetsuit: Also called spring suits, a shorty has long or short sleeves, covers the torso and usually ends above the knee. I recommend this on warmer days or when you don't mind a few splashes.
  • Long John Wetsuit: Long John wetsuits are made of thinner material. They cover the whole body except for the arms and are designed for warmer water. If you're very warm-blooded or in a location that isn't super cold, this may be just what you need.
  • Top: This is just what it sounds like: the top. It has short, long or no sleeves and can be worn with shorts, swim trunks or a separate bottom wetsuit (mentioned next). There's usually a zipper down the front. This is a great choice because of the ease in donning and doffing (putting it on and taking it off in SCUBA-speak).
  • Bottom: This is just the bottom (like a pair of shorts but form-fitting and made of neoprene). It has short or full-length legs and can be worn with a rashguard top, a T-shirt or a wetsuit top (mentioned above). I recommend this type for things like fly-fishing or jet-ski riding.

Features of the Best Cold Water Wetsuits

Since wetsuits, in general, are designed to keep you warm, there are several specialty processes used in their construction that makes them suitable for watertight wear.
  • Flatlock Stitching: Flatlock stitches lie flat against your body. This type of construction is designed for water above 62 degrees as some water may get in.
  • Glued and Blindstitched: The neoprene pieces are glued and then stitched with a process known as blindstitching. Blindstitching is when the needle doesn't go all the way through the fabric. It comes back out of the same hole it went into. This process makes for a very watertight seal. It's meant for use in water that's 55 degrees and up.
  • Sealed and Taped: For the ultimate cold water protection, you'll want to choose a sealed and taped wetsuit. The sealed and taped process is where the neoprene is glued and blindstitched and then has an interior seam tape to add durability. This type is meant for water 55 degrees and below.
  • Zipper: Wetsuits can have back or chest zippers or even be zipperless. Back zippers usually have a long leash that allows you to easily grab to zip and unzip it. You'll want to make sure you have the zipper pulled up all the way, otherwise, you could end up with leaks.

A rashguard is a great choice when it's not super cold out. It works similar to a wetsuit in that it traps a small amount of water inside to keep you warm. Sometimes, just that extra bit of fabric covering your arms is all you need. 

Neoprene Gloves

Choose a pair with a textured grip on the palms for a secure hold on that ski line. If you're into sailing, cold water sailing gloves are the way to go.

Neoprene Boots

Who would've thought about wearing boots on the water? I sure didn't. But the same neoprene boots that divers wear can keep your feet just as warm on that wakeboard or waterski.

They usually have soft rubber soles with a textured bottom grip and are about ankle length in height.

Neoprene Hoods

They all say that the best way to keep warm is to wear a hat. Whoever "they" are have a point.

But you can't just wear any old hat while you're zipping around the lake. You'll want a neoprene "hood-type" topping that can be secured to stay on. They're made of soft neoprene that fits over your head and rests on your shoulders.

Features include four-way stretch, anatomical contouring and watertight seals around the face. Divers use these while diving in cold water. If it works for them, it must be great above the water, right?

You'll want to take into consideration the wind, air temperature, your level of activity and if/how long you'll be in the water (rather than just getting occasional splashes).
