WHAT TO WEAR UNDER A WETSUIT IN COLD WATER

Snorkeling and scuba diving are among the most enjoyable water sports activities. You can snorkel or go scuba diving just to chill on a weekend or during your vacation.

However, before getting into the water, you should wear a wetsuit. You also need to know what to wear under a wetsuit to have an enjoyable experience. You can choose what to wear depending on your preferences.

Before we continue, let’s find out why you need to wear more layers of clothing under your wetsuit.

Why You Should Wear Layers Under Your Wetsuit

Is it really necessary to wear layers under a wetsuit? Well, the answer is “Yes” for the following reasons:

Protection and Insulation

Undergarments help to keep the body warm when you are snorkeling in areas with cold temperatures.

You can always wear a thick wetsuit to keep warm. However, the heavy garment will restrict your movements and make you tire quickly. Wearing thin fabric layers under the wetsuit helps to insulate the body against the cold without draining your energy.

When snorkeling, you will encounter different temperatures. Before choosing what to wear under a wet suit in cold water, consider how cold the water is, the air temperature, and the wind above the water.

You should also know the right type of clothing (one-piece, full-body or two-piece) to wear. Ensure that the garments are made from materials that will keep you warm throughout your stay on the water.

There are also wet suits that can protect you against UV rays. Wearing these garments will protect you against scrapes, stings, bites, and cuts. The wetsuits serve as thin layers between your skin and the elements.

Decency

Snorkelers often change into their swimming wear in open places like a beach. However, wearing and removing wetsuits is not easy. This is not something that can be done quickly while covering yourself with a towel. Moreover, you may feel uncomfortable standing around in your speedos or bikini while having lunch.

Therefore, you need something that will cover you up. You can cover yourself by wearing a thin rash guard, bathing suit, or any other type of clothing underneath the wetsuit. This way, you can change the wetsuit without feeling embarrassed. 

Hygiene

Renting a wetsuit may not be an option if you don’t want your skin rubbing where other people have rubbed on before. It’s not hygienic to wear a wetsuit that was worn by someone else who may not have worn anything under it.

It is also advisable to wear some undergarments since some people pee in their wetsuits. You can wear some trunks or swimsuit for hygiene. 

Comfort

Most snorkelers prefer going nude under their wetsuits. However, this can be uncomfortable as the skin rubs constantly against the inside of the wetsuit. For some snorkelers, the skin starts to feel sore and chafe after wearing a wetsuit for a long period of time.

The areas that suffer from wetsuit chafing include the crotch, neck, behind the knees, and armpits. To avoid this problem, apply anti-chafing cream or gel. However, wearing lycra or spandex underneath is the best solution. 

What to Wear Under a Wetsuit (for Men & Women)

What women should wear under their wetsuit isn’t the same as what men should. Here is an overview of the garments to be worn:

What Men Should Wear Under a Wetsuit

Rash Guard

It’s important to keep warm when snorkeling or scuba diving. There are various wetsuit undershirts that you can go for. However, a compression shirt or rash guard makes for the perfect layer in cold water. You can wear the shirt or rash guard to keep your arms and torso warm, and diving shorts to keep the legs warm.

Like is the case with diving shorts, compression shirts help to keep you warm and prevent the wetsuit from rubbing against your skin. The rash guard short sleeve shirt also improves blood flow to your heart.

You can also go for a long-sleeved shirt, if you are snorkeling in very cold water.

Things to Consider

  • Wear a sports bikini as it fits tightly compared to a normal bikini
  • Wear a sports bra under your suit and combine it with compression or spandex shorts.
  • Avoid wearing jumpsuit with large buckles or knots as this can dig into your skin. Instead, use streamline suits and flat clasps.

Conclusion

If you are wondering what to wear under a wet suit in cold water, you have a variety to consider. If you have a wetsuit that you use when the water is warm, you can wear a rash guard or a jumpsuit with it.
