Product Information
The SCUBAPRO Definition Steamer, Men, 7mm is a CE Class A full wetsuit for recreational cold-water diving, built from petroleum-free, limestone-based X-Foam neoprene with an infrared interior lining that reflects body heat and a diagonal rear YKK zipper with brass slider. SCUBAPRO rates it for water from 50°F to 60°F (10°C to 15.5°C), with secondary use below 50°F (10°C), and it replaces the brand's former 6.5mm Definition Steamer.
Who it is for
This steamer suits the recreational diver who wants one warm, stretchy full suit for temperate to cold water: local shore and boat diving, cooler seasons. SCUBAPRO rates it for water from 50°F to 60°F (10°C to 15.5°C), with secondary use below 50°F (10°C). The Ultraspan chest panel and Stretchtec fabric across body, sides, arms and legs keep 7mm neoprene from feeling restrictive. With sizes from S to 4XL, including short and tall options, it also fits divers who struggle to find proportional sizing in thick neoprene.

Frequently Asked Questions
How should a wetsuit fit?
A wetsuit should feel snug everywhere, with no loose pockets at the lower back, armpits, or behind the knees where water can collect and flush. It will feel tighter than normal clothing on land, which is expected, because the suit works by holding a thin layer of water that your body warms. If you cannot take a full breath or the neck chokes you it is too small, and if you can pinch loose folds of neoprene it is too big.
What do you wear under a wetsuit?
Most divers wear a swimsuit, a rash guard, or a thin dive-specific base layer under a wetsuit. A slick base layer makes a tight suit much easier to pull on and cuts down chafing at the neck, shoulders, and underarms. Avoid thick cotton clothing, which soaks up water, bunches, and makes you colder rather than warmer.
How do you put on a tight wetsuit?
Work upward in small sections, pulling a little neoprene at a time rather than yanking on one spot, and get the suit fully seated at the ankles and knees before working on the hips and shoulders. A plastic bag over each foot and hand, or wetting the suit first, helps it slide into place. Grip with flat palms rather than fingertips, since fingernails are the most common cause of torn neoprene.
Does a thicker wetsuit mean a warmer wetsuit?
As a general rule, thicker neoprene insulates more, so a higher millimeter rating is warmer in the same conditions. Warmth also depends heavily on fit, suit style, seam construction, whether you add a hood, boots, and gloves, how long the dive is, and your own cold tolerance, so two divers in identical suits can feel very differently. Use thickness as a starting point and refine it against your local conditions and personal experience.
How do I care for and store a wetsuit?
Rinse it inside and out in fresh water after every dive day, and use a wetsuit-specific wash occasionally to control odor. Dry it inside-out first and then flip it, always out of direct sunlight, because UV and heat break down neoprene faster than anything else. Store it hanging on a wide-shouldered hanger or laid flat rather than folded, so you do not set permanent creases.
How long does a wetsuit last?
Lifespan depends far more on use and care than on age, so a suit dived hard in sun and chlorine may soften within a couple of seasons while a well-rinsed occasional-use suit can last many years. Signs a suit is finished include compressed neoprene that no longer feels buoyant or warm, splitting seams, and looseness in areas that used to be snug. Repairing small cuts and seam separations early adds meaningfully to a suit's life.
What is the difference between a full suit, a shorty, and wetsuit separates?
A full suit covers arms and legs, a shorty stops at the upper arms and thighs, and separates such as tops, bottoms, and hooded vests layer to add warmth where you want it. Layering a vest or top under a full suit adds core warmth and can extend the range of a suit you already own. Choose based on how much coverage you want, both for warmth and for protection against stings and abrasion.
What water temperature is the Definition Steamer 7mm rated for?
SCUBAPRO rates this 7mm steamer for primary use in water from 50°F to 60°F (10°C to 15.5°C), with secondary use below 50°F (10°C). It carries a CE Class A thermal protection rating. Actual warmth also depends on fit, dive length and whether you add a hood, boots and gloves, so divers who run cold often layer a hooded vest for the colder end of that range.
Does this 7mm model replace the 6.5mm Definition Steamer?
Yes. SCUBAPRO states that this 7mm Definition Steamer replaces the former 6.5mm version of the suit. The current model keeps the Definition platform features, including the Ultraspan chest panel, Stretchtec fabric, infrared fleece interior, diagonal rear YKK zipper with brass slider, and spine and lumbar pad, in 7mm X-Foam neoprene with a CE Class A rating.
What is X-Foam neoprene and why does Scubapro use it?
X-Foam is a 100% petroleum-free neoprene made from limestone rather than oil-based feedstock. Scubapro uses X-Foam in this Definition Steamer, and the suit is assembled with solvent-free glue as part of its green manufacturing process. Divers get the same 7mm thickness and CE Class A thermal rating from a 100% petroleum-free, limestone-based foam.
Which sizes are available, and what do MT, LS and XLS mean?
Thirteen sizes are published: S, M, MT, LS, L, LT, XLS, XL, XLT, 2XLS, 2XL, 3XL and 4XL. MT, LT and XLT are tall cuts, while LS, XLS and 2XLS are short cuts, so torso, arm and leg length stay proportional for divers who are taller or shorter than standard. Each suit also has size indications printed on the wrist seals.
Review summary
This is a 7mm men's full wetsuit from Scubapro built for cold-water diving, with written reviews still few at this point. It is made from limestone-based, petroleum-free X-Foam neoprene and targets water in the 7 to 12 degree Celsius range. It has an Ultraspan chest panel and Stretchtec fabric through the body, arms and legs, a diagonal rear YKK zipper, an infrared interior lining, a padded spine, and abrasion-resistant shoulders and seat. It suits divers who need steady warmth in cold conditions.
