Wetsuits — How to Choose & Fit
We've been fitting surfers on the East Coast for 30+ years. This guide walks you through wetsuit thickness by water temperature, how a suit should fit, and which brand matches your body type — so you stay warm and surf longer.
A warmer wetsuit isn't just a thicker one. Four things decide how warm you'll actually be in the water — get these right before you shop by millimeters.
Fit comes first
A suit that flushes water feels colder than a thinner suit that fits right. Nail the fit before you worry about thickness.
Water temp, not air temp
A sunny day can still be freezing in cold water. Match your suit to the water and you'll last far longer in the lineup.
Seams & zip
Chest zips and glued/blindstitched seams cut flushing and hold warmth better than back zips and flatlock stitching.
Cover the extremities
Hands and feet go cold first. Boots — then gloves and a hood — extend your season more than extra suit thickness alone.
Thickness
Wetsuit thickness by water temperature
Use this as a practical starting point. Wind, session length, and your personal cold tolerance matter too — if you "run cold," size up the warmth.
Rule of thumb: water temp matters more than air temp. A sunny day can still feel freezing in cold water. When in doubt, choose warmth and you'll surf longer.

Fit
How a wetsuit should fit
Fit is the #1 factor for warmth. A good suit is snug — they aren't easy to get into, and they're restrictive by design. You want snug without being so tight it compresses the neoprene's air bubbles and kills the insulation. Give and take: snug in the chest beats loose anywhere else.
Good fit looks like
Snug at neck, wrists, and ankles
No big loose pockets behind knees or lower back
Minimal water movement inside the suit
Full range of motion without shoulder pain
Red flags
Baggy arms/legs that "balloon" with water
Neck gap that lets cold water rush in
Excessive pulling on shoulders or crotch
Hands go numb fast (usually from flushing)
01
The undershirt trick
What size shirt would you wear under a pressed dress shirt and tie? If that's a Large, you'll wear a "L" wetsuit 90% of the time — bump to LT if you're tall, LS if you're short.
02
Never size down in the waist
The most common first-timer mistake. Bagginess at the waist and upper thigh is where a suit pools cold water — miserable fast. Fit the waist snug.
03
The tightness test
Zipped up, grab the neoprene at your sternum and pull. If air rushes in to fill the space, it's not too tight. If it snaps back with no air, it may be.
04
New suits run tight
Your old suit stretched out with use (which is why it stopped keeping you warm). A fresh suit hasn't broken in yet — and once it's wet, it gets much more flexible.
Between sizes? Nothing beats trying one on — especially for a first suit or a brand switch. Come in, or call the shop at (843) 884-1035. 30+ years of combined wetsuit experience and we'll dial in your fit.
Brand fit
Which brand fits your body type
Every manufacturer's sizing runs differently — one company's "M" isn't another's. O'Neill and Rip Curl have the most reliable, tightest-tolerance sizing. Read the size charts, use a tape measure, and measure your waist about an inch below the belly button.
Best seller
O'Neill
Broad / stocky builds
The rugby / football / weightlifter build — the person people call to help move a sofa. Athletic-cut undershirt and you can see your pecs? O'Neill is likely your brand.
Our pick: the O'Neill Hyperfreak line — our best-selling wetsuit.
If there's less than an 8" difference from chest to waist (based on a Large) and some clothing runs a touch "short" on you, Rip Curl is probably your fit. Tends to suit people tall for their weight.
Swimmer's build
Quiksilver
Lean with broader shoulders
Slender body and legs with larger-than-average shoulders — but not as broad as O'Neill. You're in shape, most clothing fits well, and you've got a 6–8"+ waist-to-chest ratio.
Taller / thinner
Billabong & Hurley
Lean, longer proportions
Similar lean, longer proportions to Rip Curl — thinner still. Worth trying if standard cuts run short on you and Rip Curl feels close but not quite dialed.
Styles
Wetsuit styles at a glance
From warm-water summer sessions to winter cold snaps, here's what each style is built for.
Rashguard / no suit
Warm water, sun protection, and rash prevention. Great for summer and travel.
Springsuit / shorty
Shoulder-season comfort. Keeps your core warm while staying flexible.
Full suit
The everyday East Coast workhorse. Choose thickness by water temp.
Hooded suit
Cold-water sessions. A built-in hood seals warmth and reduces flushing.
Boots
Your feet go cold first. Boots extend sessions and protect from rocks and shells.
Gloves & hoods
For winter. Keep hands from going numb and seal in warmth up top.
Construction
Seams, zippers & neoprene
Once fit and thickness are handled, these details separate a warm, long-lasting suit from a cold, short-lived one.
Chest zip vs back zip
Chest zip is typically warmer with less flushing; back zip is easier on and off. Both can be great — prioritize fit.
Seam types
Glued & blindstitched seams are warmer than flatlock. Taped seams add warmth and durability in colder suits.
Stretch vs durability
Softer, stretchier neoprene paddles easier but can wear faster. Stiffer neoprene lasts longer. The best suit is the one you'll wear often.
Make it last
Rinse with fresh water, dry in the shade, and keep it out of hot car trunks. Good care adds seasons to a suit.
Local knowledge
Charleston & South Carolina notes
In the Lowcountry, conditions swing a lot through the year. Most local surfers keep a simple rotation: a 3/2mm for the cool months, a 4/3mm for cold snaps and winter, plus boots for the coldest sessions. Building a one-suit quiver? A well-fitting 3/2mm is the most versatile pick for our water — and as fall drops temps from the summer 80s toward the 60s, it's the first suit most people reach for.

FAQ
Common questions
Snug. It should feel tight on land with no big loose areas, but you should still be able to breathe and paddle. Loose spots cause flushing and make you colder; too tight compresses the neoprene and kills insulation. Chest-snug beats loose-anywhere-else.
Broadly: O'Neill for broader/stockier builds, Rip Curl for slender/taller builds, Quiksilver for a leaner swimmer's build, and Billabong or Hurley for taller and thinner builds. O'Neill and Rip Curl have the most reliable sizing.
Use a tape measure and read the brand's size chart carefully. Measure your waist about an inch below the belly button, and have someone else measure for you if you can. Never size down in the waist.
Choose based on water temperature and cold tolerance. A 3/2mm is more flexible; a 4/3mm is warmer. If you're often cold or surf long sessions, a 4/3 is worth it. The first number is chest/back thickness, the second is arms/legs.
Yes — and we recommend it, especially for a first suit or a brand switch. Trying on in person beats guessing online. Come into our Mount Pleasant, SC shop, or call 877-560-9009 and ask for Angelo or Phil.
Rinse with fresh water after every session, dry it in the shade (never a hot dryer or direct sun), avoid leaving it in a hot car trunk, and store it on a wide hanger rather than folded or crammed.
