People need protection from cooler water. In most situations, especially with scuba divers, a thick wet suit is worn — often a wetsuit that has a thickness of 7mm.
But there are tons of water-sport brands and it can be difficult to know which to choose. We put together this guide to help you find the top available suits so that you can buy the best one for you.
So let’s get right to it — what is the best 7mm wetsuit in 2017?
Top 7mm Wetsuit Reviews
The best 7mm wet suit we’ve found is made by O’Neill, which is one of the top and most reliable brands in the industry. Check out the review below.
- Great mobility even with 7mm thickness
- Durable & high-quality materials used
- Affordable considering the brand
- Material can bunch in spots
- Pricey compared to lesser-known brands
If you need a 7mm suit, this is an excellent choice, sporting a great combination of comfort and range of motion, earning it the number one spot on our list of the top 7mm wetsuits.
This 7mm neoprene wetsuit by NeoSport features multi-layer knee pads for extra durability and flexibility. It is kind of difficult to get on, but once wearing it the range of motion is similar to other seven millimeter wetsuits. Feels great if fitted properly.
- Rock solid seals
- Pretty flexible for 7mm
- Adjustable collars and zipper flaps
- Sizing varies widely by body type
- Can be a challenge to get on
Another great suit for cold water diving. While it can be a chore to get on, it’s actually pretty flexible for this thickness. It’s a good price for the quality.
Even though it comes with already bent arms and legs (in order to “reduce fatigue”), it still starts to feel a little restrictive after using it for longer periods of time due to muscle fatigue.
- Strong but flexible
- Well-insulated and stylish
- Seams are sturdy and strong
- Starts to feel a bit restrictive after long use
- Can quickly wear around zippers
This is a good all-around one piece 7mm scuba suit — a very solid choice for beginning or experienced divers alike.
Why A Wet Suit?
People wear wetsuits during various water sports (e.g. scuba diving, surfing, or snorkeling) as a layer of protection from cold water, long-term exposure, and for other environmental and comfort reasons.
Contrary to what some people believe, wetsuits don’t keep you dry (that’s what a dry suit is for — for more info on this, see Wetsuit vs Drysuit). Quite the opposite, in fact — wetsuits work by trapping a layer of water between the suit and your body, which then heats this thin layer to keep you warm while submerged.
For diving in cooler water, a wetsuit is one of the must-have pieces of scuba diving equipment.
Finding the Best 7mm Wetsuit
Because 7mm wet suits are often worn in more extreme water conditions, choosing the right 7mm wetsuit is an important decision.
If you’re having difficulty figuring out which type of wetsuit you should buy, or if you even need a wetsuit, we put together a wetsuit buying guide to help you.
Guide to Buying a 7mm Wetsuit
Again, since wetsuits are not cheap (unless you’re trying to find cheap 7mm wetsuits that won’t last), it’s important you figure out if a seven millimeter wet suit is even the type of suit you need.
Wetsuit Thickness Matters
Wetsuits are made at a variety of thicknesses, from less than 1 mm to 7 mm and more. The thicker the wetsuit, the more insulation from cold the suit can provide. This increased insulation comes at a price, however, as thicker wetsuits come with decreased mobility. Finding the right balance between thickness and mobility is key.

When to Buy a 7mm Wetsuit
A 7mm wetsuit is considered a thick wetsuit and tends to be used in cooler water temperatures. While personal preferences will come into play (i.e. some people get cold more easily than others), people start needing a 7mm suit when temperatures drop below 70 degrees.
With water any colder than 60 degrees, you will certainly want a wetsuit that’s 7mm thick (at least), and in water temperatures this cold you may even want to consider using a drysuit.
Once you decide on buying a 7mm wetsuit, you need to figure out what size you will need, since how good the fit is will have a major impact on the wetsuit’s effectiveness.
How a 7mm Wet Suit Should Fit
Getting the right fit for your wetsuit is very important — an improper fit will not keep you warm enough or will restrict your movement too much or both.
A 7mm wet suit should be snug and without any excess material at the back or down the arms and legs. With that said, you should still be able to move without too much restriction.
Hopefully this guide has helped you find the right wet suit for you. Now go dive in!
