How Does a Wetsuit Work?
Unlike a dry suit which keeps you dry, a wetsuit is designed to keep you warm by letting in water. So, there is nothing like a waterproof 7mm wetsuit. But how is this possible? Here is how this garment works. A wetsuit is designed to fit into your body tightly.
In other words, it tends to stick to your skin. However, you will find that this garment usually leaves little room for water to enter. So, once you get inside the water, the wetsuit works by trapping just a small volume of water between it and your skin.
The trapped water is then warmed up by your body heat and acts as an insulating layer. Essentially, wetsuits are made of neoprene material which works as the insulator against cold water temperatures. So, the thicker the neoprene, the warmer you can expect to be.
Benefits of using wetsuits
Besides keeping you warm while you are submerged in cold water ranging from around 40 to 60-degrees, there are other benefits of using wetsuits. These include:
Helps you swim faster
All wetsuits are manufactured from naturally buoyant neoprene materials. This makes it easy for you to stay afloat with minimal effort. Consequently, this enables you to glide easily through the water and swim faster.
Provides safety and protection
Generally, wetsuits are made from neoprene with different thickness levels ranging from 2mm to 7mm for extreme winter conditions. So, thicker wetsuits can provide you with superior protection from abrasion and even sunburns. You also won’t have to worry about your skin getting irritated or cut by sharp objects such as shells.
Wetsuits are designed to be comfortable to wear for as long as it is necessary. So, by allowing you to stay warm while in the water, it means you can also swim for longer without feeling uncomfortable.
Another benefit of using a wetsuit is that it can help enhance your performance in the water. This is because it is designed to fit tightly into your body. And as a result, it helps compress your muscles and joints, thereby allowing you to perform better.

What To Consider When Buying 7mm Wetsuit
When looking to buy the best 7mm wetsuit, there are a few things you must look out for. But what are these things? Read on to find out.
Wetsuits come in different sizes to choose from. However, the best wetsuit is one that fits snugly on your body. This is because a loose suit will let water in and hence will not keep you warm.
Generally, a good-fitting wetsuit should not leave any space between the suit and your skin. It should fit tightly. So, make sure to check the individual manufacturer’s size guidelines because sizes differ across manufacturers.
Type of stitching
The type of stitching particular wetsuit employs will determine how well it can prevent water seepage. For most wetsuits that are inexpensive, you will find that they use flat lock stitching. Unfortunately, this type of stitching may allow some water to seep in.
On the other hand, some wetsuits are glued and blind stitched. Some products may also feature double-blind stitch and others single-blind stitch. But overall, this type of stitching is more durable and does not allow any water to seep through.
A zipper makes it easy for you to get in and out of your wetsuit with ease. Generally, most products either come with a front/chest or a back zipper. But for added convenience, you might want to consider a chest zip and back zip wetsuit.
Having said that, some wetsuits also feature zippers around the ankles and wrists to provide you with a snug fit. In addition, you should consider getting a wetsuit that utilizes heavy-duty and durable YKK zippers.
The best wetsuit brands are designed to be 100% sealed to keep water out. For some products, they come spot-taped at the stress points only. Others utilize watertight seals, which are equally good at preventing water seepage.
However, the best wetsuits usually feature Glideskin seals around the wrists, ankles, and even the neck area. Overall, this is considered the best form of a seal.
Almost all 7mm wetsuits are manufactured from neoprene materials. However, some suits are made from thermoprene, which has more stretch compared to standard neoprene.
On the other hand, you will find that some wetsuits feature open-cell neoprene construction. These wetsuits tend to be softer, comfortable, and very flexible but can be a little costly.
But when it comes to durability and comfort, you might want to consider getting a wetsuit made of double-lined neoprene. Other types of materials that are equally good include dive-grade stretch neoprene, high-stretch neoprene, and EverFlex neoprene.
There are different types of wetsuits, including shorties which are cut just above your knees. These are easy to put on and very comfortable, but they provide you with no leg protection.
Another common type of wetsuit is the full-body or jumpsuit. Although they are not as easy to wear as the shorties, they provide you with more warmth and protection.
You probably already know that choosing the best 7mm diving wetsuit for your needs is not a straightforward process. So, we hope these frequently asked questions will make it easier for you.
What temperature is a 7mm wetsuit good for?
Because of its thickness level, a 7mm wetsuit temperature can range from 45 to 60 degrees F. But it depends on your tolerance for cold and how well the wetsuit is stitched to keep cold water out.
What thickness wetsuit for 55-degree water?
A 4mm wetsuit will work if you will just be swimming. However, if you plan to do a lot of surfing or diving at this temperature range, you should consider a 5mm wetsuit.
What to wear under a 7mm wetsuit?
There is actually no right or wrong answer here because it is a personal choice. However, you should at least wear a swimsuit in case you have to change your wetsuit in front of people. You could wear a swimsuit and tee-shirt, swimming trunks, or any type of non-restrictive swimsuit. Also, you can wear a rash guard top to keep you a little bit warmer and help ease skin irritation.

Can you swim in a 7mm wetsuit?Yes, if the water temperatures are extremely cold like 40-degrees F or below. However, the suit must be very flexible to allow more movement. That said, you will find a 3mm or 5mm wetsuit the best for swimming
