A triathlon wetsuit is for hip lift. The shoulders still have to recover.

After the watch, this is the ticket

Goggles leak. Caps tear. A tech suit is a championship footnote. A triathlon wetsuit sits next to a GPS watch on the till. ZONE3’s Vanquish-X is £699 on the UK guide. Orca’s Apex Flow V2 is $1,149 on the US shop. ROKA’s Maverick X.3 is $1,345. blueseventy’s Helix is $995. That is the second-dearest swim object most age-groupers will ever buy.

People still treat it as warmth. Warmth is a side effect. The race object is body position: legs that do not drag a trough, a hip that rotates, an arm that still finds the catch at 1400 m. A surf steamer sits on a board. This suit swims, then comes off in T1. If you bought the wrong category, stop. The rest of this page will not save a 5 mm surf zipper.

Hips up, shoulders free

Every brand on this page is selling the same argument in different panels. Put millimetres on the sinking bits. Take millimetres off the moving bits. blueseventy prints it without poetry: thinner rubber flexes, thicker rubber floats. Their Helix graphic runs 1.5 mm in the arms and 5 mm where the rules allow lift. ZONE3’s Vanquish-X runs 5 mm down to 0.3 mm. Orca puts Exo-lift and Aerodome in the lower torso of Apex Flow V2 and 44+ plus 0.88 Free in the arms. ROKA patterns the whole Maverick with the arms already up so the shoulder panel is not fighting a down-by-the-side pattern.

The trade-off is not a slogan. A heavy-legged pool swimmer who still drops the hips in a lake wants the float map: thicker legs, Aerodome or lift panels, a suit the brand labels Flow or Float or Helix. A club swimmer with a decent line who hates a locked recovery wants the flex map: thinner shoulders, 40 or 44 foam, a suit the brand labels Flex or Aspire or X.3. Buying max buoyancy and then complaining the catch died is you ordering the wrong column.

Sleeveless exists. ZONE3’s Ascend sleeveless was $295 on the US collection that morning. Warm water, shoulders first. Not the default race suit. If the water is wetsuit-legal and your legs sink, keep the sleeves and spend the money on a size that zips.

Yamamoto in one sitting

Almost every race suit on this rack starts at Yamamoto Corporation in Japan. The numbers are cell grades, not marketing poetry. #38 Standard is the work foam: diving, kayaking, a sheet that needs more force to stretch. #40 Super Stretch is the triathlon and surf shoulder sheet, built by loosening #39. #39 sits in the middle and is the usual body panel because it floats well for the money. Aerodome is Yamamoto’s patented sheet with air holes; brands sandwich it for extra lift, and Orca claims about 30% more buoyancy than a conventional sheet on Apex Flow V2. SCS is Super Composite Skin, a slick coating, a surface not a cell. Orca also sells 44+ as an exclusive high-stretch mix in the Apex arms. A stiff jersey on 40 foam will still feel cheaper than a stretch jersey on 39. Read the panel map, not the biggest number on the hang tag.

Fit or the suit is waste

I will be blunt. A £700 suit that bags at the lumbar, or that stops a full breath, is a bin bag with a YKK zip. Neoprene only works when it is a second skin. Water flushing through a gap is drag you paid to add. A chest you cannot inflate is a panic you will remember at 200 m.

ROKA’s own fit copy is the useful one. The suit should feel tight on land. Expect help with the zip. Expect ten to twelve minutes the first time if you sized down inside the chart. If it constricts breathing or the shoulder in the water, size up. ZONE3 says the same split: size down to race, size up if you will live in it for long training. blueseventy splits Race Fit and Comfort Fit on the Helix finder. Race Fit is slow to don and faster in the water. Comfort Fit is the opposite. Pick the job. Do not pick a colourway.

Length is the silent miss. Air at the small of the back is usually a longer torso, an MT or a Tall, not a smaller chest. Fingernails are how you turn a new suit into a warranty argument. Pads of the fingers. Plastic bags on the feet and hands if you must. Rinse after salt or chlorine. Hang from the waist, not the shoulders. Orca prints that last line because people wreck the thin arm panels on a coathanger.

Five millimetres, then the thermometer

World Triathlon’s FAQ is the short dictionary. Wetsuits cannot exceed 5 mm thickness. A two-piece is legal if the overlap is still no thicker than 5 mm. Hands, face, and feet stay uncovered. When the suit is mandatory it must cover the torso. Socks in the swim only when the suit is mandatory.

Water temperature is measured, then announced. For age-groupers from the youngest category through 55 to 59, a wetsuit is forbidden at 22°C and above on swims up to 1500 m, and at 24.6°C and above on 1501 m and longer. It is mandatory at 15.9°C and below. From 60 to 64 upward, the 24.6°C forbidden line applies at every distance. IRONMAN’s age-group legal ceiling is 24.5°C. The local athlete guide can still be stricter. Check the week of the race. A £1,000 suit in a non-wetsuit swim is a transition bag ornament.

ZONE3

ZONE3 is the British rack I trust for a clear ladder. Their wetsuit guide still listed Vanquish-X, Aspire, Vision, Advance, Agile, and Glide on 23 August 2026. Vanquish-X is the elite sheet: Yamamoto #40 and #39, 5 mm to 0.3 mm, SCS, X-10 Extreme shoulders, Aerodome, £699. Aspire is the competition suit most people should actually buy. UK list £549. US list $995. B-Prene by Yamamoto, X-10 shoulders in #40, #39 body, Aerodome on the men’s suit, SCS they print at a 0.021 drag coefficient. Vision is the 2024 Triathlete winner still on the rack at £399 / $795. Advance at £299 is the first Yamamoto #39 mix. Agile at £219 / $395 is the honest first full-sleeve.

ZONE3 prints Loughborough Sport testing across the range. A lab, not a miracle. Use it as “these suits change speed and load,” not a promise that Vision beats Apex Flow on your body. B-Prene is their biodegradable Yamamoto sheet in Vision and Aspire. Landfill claim, 30% in 522 days. Not a reason to size wrong.

Orca

Orca split the old names. Predator and Sonar became Flow. S7 became Float. Equip became Flex. The 2026 flagship I opened is Apex Flow V2 at $1,149 on the US site and €869 on the European shop. Yamamoto 44+ and 0.88 Free in the arms. Exo-lift and Aerodome in the lower torso. They say it is for a decent stroke that still wants the hips held. Apex Flex V2 is the shoulder-first sibling at $859. Apex Float V2 is the max-lift sibling at $699. Athlex Flow V2 sits at $599 / €479 as the balanced mid. Athlex Float V2 was $399 on the related rail.

Orca’s UK homepage that morning was selling Vitalis open-water suits, not the triathlon Apex rack. Buy triathlon from the triathlon URL. A Vitalis TRN at £219 is a visibility training suit. It is not Apex Flow.

ROKA

ROKA is the US till at the top of the mountain. Maverick X.3 is $1,345. They call it the fastest suit they make. ARMS-UP patterning, RSX centreline buoyancy, Aerodome in the new build, catch fabric on the forearm, 2 mm ankle panels so you can kick out in T1. Pro Max is $995 if you want lift without the X.3 ticket. Comp.3 is $565, still ARMS-UP, still RSX, the entry they call the best first Maverick. Tall sizes exist. Use them. Ignoring Tall is how long torsos buy a bag of water.

blueseventy

People still type BlueSeventy. The shop is blueseventy. Helix is $995. Yamamoto throughout, seamless shoulders, 1.5 mm arms, lift panels on the quads, reverse zipper so the pull is fast in T1. They print a 55°F / 12.5°C minimum and they tell you to train in another suit. I agree. Reaction is $680. Fusion $420. Sprint $325. Helix 2023 leftovers were $500 exchange-only. That is a closeout, not a current Helix.

What the tills said on 23 August 2026

Official shops that morning. Sale stickers move. Lists do not make a suit faster. GBP from ZONE3 UK. USD from Orca, ROKA, blueseventy, and ZONE3 US. EUR from Orca Europe where the US page was silent on pounds.

If this is the first neoprene

This page is the race rack. It is not the first-lake lesson. A first full-sleeve can be ZONE3 Agile, ROKA Comp.3, blueseventy Fusion or Sprint, Orca Athlex Float if the legs sink. That job lives on best beginner triathlon wetsuits. Do not let a shop talk you into Vanquish-X because you have an autumn 70.3 and a winter of 2,000 m Tuesdays. The suit will not invent the Tuesdays.

Chop and glare are best open water swim goggles. The wrist that counts the lake loop is best swim watches. Put them in the bag. Log the session when you get home. A wetsuit morning without a course note is a time you will misremember in March.
