How to choose the best diving wetsuits?

There are several aspects which one should consider before buying a scuba diving wetsuit.

Size – The main factor before buying a diving wetsuit should depend on proper fit and comfort, which comes from picking up the right size. Sizes differ from brand to brand, so always check the size chart before purchasing.

Selecting the right size is particularly important. If you pick a too large wetsuit, water could leak in and pick up a too-small size, which will be difficult to put on. A scuba diving wetsuit should fit snug, so going for one size smaller can be a good choice. Otherwise, wear it and try to stretch your hand and body or try touching your toes to verify the fit.

Thickness –  Diving wetsuits come in varying thickness and is always measured in millimeters. The thickness range from 1mm to 7 mm. The thinner the suit, the more specific it becomes for warmer conditions.

For cold water diving, go for higher thickness. So, select a suit that’s suitable for the waters you’ll be diving in. Before departing, it is recommended to check the average water temperature from the local diver in that season and then decide on the diving wetsuit.

Style – Scuba wetsuits come in three different types. Regular Divers go for Full wetsuits as it gives more warmth. Occasional divers or beginners opt for a shorty wetsuit that has short sleeves and goes till the knee.

Shorty wetsuits are easy to put on. For very cold water, a Farmer John (Jane) wetsuit is preferred as it comes in a two-piece. It’s, in-fact, double-up the insulation.

Material – Scuba diving wetsuits are made up of open-cell neoprene, closed-cell neoprene, and lycra fabrics. These materials act as an insulator and minimize water quantity that penetrates the suit and keeps body heat from escaping.

Among the three options, closed-cell neoprene is the most commonly used material with a rubbery feel and is rigid. If you want a softer and flexible material, look for open-cell neoprene make. They are best for both warm and cold water diving options.

Lyra wetsuit, on the other hand, is very thin and can be used only in warm water diving where thermal insulation is not needed. They do help in protecting your skin from the sun, sharp corals, etc.

Gender – Nowadays, wetsuits are available in both men’s and women’s versions. So one can buy according to one’s fit and comfort. You even have an option to opt for unisex gear if you don’t want to invest in two products.

Besides your comfort, fit, and quality of the suit, do take a look at other features like the zippers, wetsuit’s seals, kneepads, and stitch. Many scuba diving wetsuits have a personal interior lining that allows them to dry more quickly and adds extra warmth and comfort. The price factor depends on the buyer’s ability to spend.

Some frequently asked questions

1. Can I dive if I am not a good swimmer?

Yes, you can. You don’t need to be a good swimmer for getting an introductory diving experience, but it always an added advantage to have some degree of comfort in the water. Some diving centers on local beaches offer recreational scuba diving for tourists, accompanied by trained divers to get an all-out first-hand experience in diving.

2. How to clean my scuba diving wetsuit?

Most of the diving wetsuits can be hand washed using wetsuit shampoo. A wetsuit shampoo is readily available online as well as from a retail dive store. It is not always recommended to machine wash these wetsuits to help maintain the neoprene fabric. However, you can go for a hand wash cycle option and take it out before the spin cycle process.

3. How do I choose between a drysuit and a wetsuit?

A dry suit is preferred in very cold water conditions as they prevent your body from heat to conduct away from your body. A wetsuit is perfect for mild and warm water diving conditions. Hence the water temperature is key in deciding whether you buy a drysuit or wetsuit.

4. Can I wear my surfing wetsuit for scuba diving?

Technically no. Surfing is done above water, and scuba is an underwater activity. So they are different altogether. Surfing wetsuit is very thin in comparison to scuba wetsuit. You need a thicker and warmer wetsuit for going underwater, especially for cold water diving.

5. What is the minimum age for diving?

The minimum age required to undergo this adventure activity is 10 years.

Final Words

So if you’re buying your scuba diving wetsuit, consider choosing any of the above listed highly-rated, best-selling diving wetsuits on the market today.
