Summary
Fantastic look. Super comfortable. The swim matches the suit.
The Akula is Sumarpo’s high-end race suit — “the Shark” in the range — sitting under the Prana Core and above the Victory and Vanguard. Yamamoto #40 at 1.5 mm through the shoulders, Aero Boost 5.0 in the sides, Bio-Skin scale texture on the torso, SQ-Flex lining, V-shape ankles, SCS coating, two-year warranty. At $979.95 it is proper mid-to-high money. On test it earned it.
The suit closed well, the stroke stayed free, and the body line felt effective rather than floaty-for-the-sake-of-it. If you want a race wetsuit that looks like race kit and swims like it, this is the one.
PROS
– Looks and feels amazing off the hanger and in the water
– Super comfortable through the shoulders and chest
– Very effective swim — free stroke, usable lift, clean T1
– Bio-Skin scale panel is not just graphics. It sits flat and sheds water
– Aero Boost 5.0 in the sides holds a line without turning you into a ski
– V-shape 1.5 mm ankles come off clean
– Two-year material warranty and a test-swim return
CONS
– $980 is premium money. You are buying the look and the #40 rubber, not an entry ticket
– Strong buoyancy. If you already swim very high, you will feel the extra lift
– Textured Bio-Skin wants bags on the feet and nails off the chest

Initial impressions
It looks expensive. On the hanger it feels it.
Sumarpo calls the Akula the Shark. The aurora chest and gold AKULA down the honeycomb panel are why. This is not a quiet black suit. Off the floor it looks like the top of the range even though Prana Core still sits above it.
The build list is the serious half. 100% Yamamoto limestone neoprene. 1.5 mm #40 and SQ-Flex through shoulders, sleeves and armpits — brand claims 630% elongation there. Aero Boost 5.0 in the side panels. Bio-Skin scale texture across the torso. SCS on most of the suit. Slip Skin lining made with recycled bottles. Hidden YKK zip. Ti-α-Seal at neck and cuffs. V-shape 1.5 mm #39 ankles.
In the hand the rubber is soft where you rotate and denser where the scales sit. The included bag in our pack is a proper neoprene stuff sack, not a mesh afterthought. That is a small thing and it is the first sign the suit is finished.
It sits above Vanguard in the family. Vanguard is the all-rounder. Akula is the one you buy when the look and the stroke both have to be right.
FIT
Close. Not a fight.
Fit on the men’s suit we wore was clean. Chest and shoulders closed without the usual wrestling match. The aurora panel sat flat. No crease across the zip. Gold taping on the legs landed where it should.
The collar is the detail most premium suits still get wrong. Ti-α-Seal is there to cut chafe and hold heat. On dry land it is snug, which is what you want. In the water it stayed put without sawing. If you have a long neck and hate high collars, try it on before you commit — Sumarpo’s test-swim return exists for that.
Sizes run the full in-between set: ST, SM, MT, ML, LT as well as the standard row. Use the chart. Aero Boost only works when the side panels are on you, not floating around you.
Get the size right on the hanger. Swim it. If it is wrong, send it back inside 30 days.
Comfort & Performance
Super comfortable. Very effective in the water.
Comfort is the first note and it held up on the rocks and in the sea.
Shoulders stay free. That is the #40 plus SQ-Flex doing the job, not a catalogue line. Combined with the 0.3 mm BRS feel-panel on the arm, the catch does not feel blank. You get some water, not a sleeve of dead rubber. Low Modulus Tech is the brand name for “less fight per stroke.” On test that tracked. We could stand T-pose on the reef in it without the suit pulling the arms down.
Buoyancy is the second half. Aero Boost 5.0 in the sides is meant to lift evenly, not just dump you onto your chest. That is how it swam. Effective, not cartoon. If your legs already sit high you will notice extra lift. If they don’t, this is the point of the suit.
Bio-Skin is the texture you see in the photos. Scale pattern on the torso. Translate it: water wants to leave the chest instead of sticking. SCS does the same job on the smooth panels. Together they are why the suit feels fast at the same effort, not because a graphic says Shark.
T1 is built in. V-shape 1.5 mm ankles and Slip Skin lining come off without a beach fight. For a 70.3 that is free time. For a training loop it is simply less faff.
Warmth: brand says down to 8°C. We were not in 8°C water. Treat that as the floor, not the brief. For temperate open water the thickness map is in the right place — thin where you rotate, denser where you need the line.
Durability
Yamamoto limestone throughout, glued construction, hidden YKK, two-year material warranty. After a salt session the aurora panel and gold print still looked new.
The textured Bio-Skin is the bit to respect. Bags on the feet. Nails off the chest. Do not stand on the legs to yank them up. Scratch panels under the collar and in the lower body are there for rotation, not for rocks.
Rinse after salt. Stuff it in the bag it came with. That is the care list.
VERDICT
Looks amazing. Feels amazing. Swims like the ticket.
We would buy the men’s Akula for comfort, the stroke and the fact it does not look like a training brick. At $980 you are in mid-to-high money. The rubber and the fit justify it if this is your race suit. If you want the same brand for less, Vanguard is the all-rounder below it. If you want the absolute top of the tree, Prana Core still sits above.
For temperate open-water racing in the suit we wore, the Akula is an easy recommendation.
