Comprehensive Weight Guide | How Much Weight For 5mm Wetsuit

One of the most important things to consider when shopping for a wetsuit is its thickness. A 5mm suit will keep you warm, but it isn’t going to be as buoyant in water.

Buoyancy is essential if you are trying to dive from a boat or surf big waves so it’s worth making sure that your suit has enough weight built-in before buying one. How much weight for 5mm wetsuit need? Read on and find out.

What Is A 5mm Wetsuit And What Does It Do For You?

A wetsuit is a piece of clothing worn by people who go swimming in cold waters. It helps to keep the body warm and also provides insulation from sharp currents or rocks as well as protection against stings, bites, scrapes, and scratches.

The thickness of your suit varies depending on where you are going to be using it, for example, driving won’t require the same amount of buoyancy that surfing will demand so there’s no need to wear something super thick underwater if you’re just snorkeling with friends around coral reefs.

Typically, you will need to wear about 40 pounds of weight if you want your suit to keep you afloat. This is because the water gets less dense as it cools and this means that without any extra help, the buoyancy isn’t enough for someone who weighs more than 150lbs.

Because this suit will be able to support your body much better than thinner suits do. It may seem like all these weights don’t make sense but once you’re out there experiencing what they can really do, trust us it makes perfect sense.

If anything ever seems too complicated or confusing, just remember that if you wear 40 pounds with a thin wetsuit (like the ones used for scuba diving), chances are high that you’ll sink right away.

On the flip side, when you wear 70 pounds with a thicker wetsuit (like the ones used for surfing), chances are high that it will be much easier to stay afloat.

How Much Weight For A 3mm Wetsuit

If you have a thin wetsuit, then it’ll need about 30 pounds of weight to keep its buoyancy. This will depend on how deep the water is but as a general rule of thumb, this much weight should be enough for most people who want to keep their bodies afloat in shallow waters.

And finally, if you have no idea what kind of suit you’re going to wear and just don’t feel like doing any calculations at all try your best with 20 lbs or less.

because that’s probably not enough anyway although some surfers do manage just fine by wearing lighter suits which only offer them minimal protection from sharp objects and bruises while they play around in the waves. Next time we’ll explore different kinds of wetsuits so stay tuned.

The Top Benefits Of Wearing A 5mm Wetsuit

There are many benefits to wearing thicker wetsuits in cold waters, including:


The insulation that your body gets from the suit will help you stay warm and comfortable even when swimming around in temperatures below 40 degrees Fahrenheit (approximately four Celsius). That is better than having to wear something thinner with no buoyancy.

Protection Against Stings

If you’re worried about getting hurt by marine stingers or creatures like jellyfish while out on the water then it’s best to protect yourself fully before heading out.

You can do this by either putting on multiple layers of clothing, which sometimes isn’t enough protection for people who have sensitive skin; or wearing a thick layer of neoprene instead, just like you would with a wetsuit.

 Protection against scrapes and scratches

Beaching yourself on sharp rocks or coral can tear up your skin quickly so it’s best to be protected completely before going out into the water to play around in. This means wearing thicker clothing like full-body wet suits.

A Few Things To Consider Before Buying Your First 5mm Wetsuits

There are a few things to consider before you go out and buy your first suit. Firstly, think about what activities you’ll be doing in the water because this will tell you how much weight is needed for buoyancy purposes.

If you’re just going off into deeper waters to snorkel then there’s no need to wear anything super thick but if diving from boats or surfing big waves then it’s best that you have something more sturdy on so that there isn’t any risk of injury once in the water.

Also, make sure that your new wetsuit fits well with good seams and stitching along every inch otherwise, the neoprene may become ripped which could cause harm while swimming around.

Finally, consider the durability of your suit and how often you’ll be using it. If you’re diving around reefs or just going for a quick snorkel then there’s no need to wear something super thick but if surfing big waves in colder waters is what you love doing then having thicker neoprene on will help keep out any currents while still providing warmth.

Wetsuit thickness varies depending on where they are worn and by whom. How much weight is needed depends on which activity is being done as well so make sure that before buying one, all factors have been considered carefully. Be safe when wearing these suits near water.

Tips On Caring For Your New Wetsuit

  1. Get rid of saltwater ASAP after getting into deep waters. Salt is like poison for wet suits so be careful not to soak up too much before removing yourself from where there’s saltwater nearby otherwise, you’ll have damaged your precious purchase.
  2. Dry off completely once back at shore with a towel right away. Whether it’s rainwater or seawater, don’t let it stay on the surface for too long because this can also cause damage to the neoprene.
  3. Store your suit properly after use, away from water at least for a few hours or overnight before putting it back in its original packaging and storing them somewhere dry like a closet. If you put on wetsuits frequently then having more than one will help with this process too.
