5mm vs. 7mm Spearfishing Wetsuits: Which Thickness Gives You the Edge in the Water? 

Choosing the right spearfishing wetsuit is essential because it defines who wears it and the pleasure felt in the water. Various factors can affect your dive, such as The wetsuit's thickness is another factor. To decide based on the type of diving one would prefer, one must differentiate between the 5mm spearfishing wetsuit and the 7mm spearfishing wetsuit.

What is a Spearfishing Wetsuit?

A wetsuit is the clothing used for spearfishing, providing thermal insulation, buoyancy, and the diver’s cover. Bulky, thick, and all but for water-tight, neoprene wetsuits to be used while spearfishing make you warm in cold water, protect you from the dangers of the underwater world, and give adequate flexibility. That is why one of the factors that defines the level of thermal insulation of a wetsuit at underwater temperatures during the divers’ activity is the width of the neoprene used.

Key Differences Between 5mm and 7mm Spearfishing Wetsuits

1. Thermal Insulation:

As one learns from the names of the two different wetsuits, the thermal protection that the two provide is the most important and sole differential factor between a 5mm spearfishing wetsuit and a spearfishing wetsuit 7mm. It affords ample float for water that can be as chilly as 60 to 70levels Fahrenheit or 15 to 21 levels Celsius, utilizing only a 5mm thin neoprene wetsuit. It also provides the advantage of the ability to resist expansion and contraction and that it can expand and contract for efficiency in moderate temperatures.

On the other hand, a 7mm wetsuit provides better thermal properties and is used where the water temperature is below 60 F (15 C). The thickness of the neoprene affords one the warmth, which is very important, especially if you are going for long dives in cold water. 

2. Flexibility and Comfort: 

Compared to the 7mm spearfishing wetsuit, the 5mm one is less rigid and requires less range of motion strictly limited in any direction. This added flexibility helps in activities that need quick and sudden movements, like spearfishing. The 5mm wet suit facilitates better fitting, and the least fatigue may likely be experienced when on longer dives. 

Alternatively, a wetsuit for spearfishing of 7mm tends to be rather stiff because of the increased thickness of the neoprene. It does this while offering better heat retention but at the cost of slightly less flexibility. This may affect the comfort and space utilized when maneuvering, especially when diving in warmer waters, which would require less insulation. 

3. Buoyancy: 

Thickness impacts Buoyancy: a 7mm wetsuit makes a diver thicker and will also impact buoyancy. The thickness increases buoyancy, which is beneficial greatly if you are in cold water and wish to achieve a neutral buoyancy. On the other hand, having less thickness, as is seen with the 5mm thick wetsuit, will afford the wearer less buoyancy, yet this is desirable, especially when swimming in warmer waters where buoyancy is not a major concern as it is with warmth. 

Wrapping Up

It depends on the surroundings you want to dive into and the clients' preference between a 5mm spearfishing and a bare spearfishing wetsuit 7mm. The 5mm is recommended where the water is not extremely cold but still relatively cool, where you get a good combination of warmth and flexibility at the same time. 

The 7mm wetsuit is used where the water is much colder, although the thickness of the neoprene provides excellent thermal protection. Consider the temperatures of water you expect to work in, the degree of mobility you require, and your aptitude to select the most appropriate workwear for spearfishing trips.
