Marlin Women’s Open Water Triathlon Wetsuit

45+ years of wetsuit expertise. A proven Marlin heritage. Re-engineered for the modern female swimmer.

Designed and developed by Northern Diver, the Marlin Women’s Open Water Triathlon Wetsuit brings together decades of wetsuit manufacturing experience with advanced Yamamoto neoprene and performance-focused technologies. Designed specifically around the female body shape, it delivers a close, second-skin fit without restricting the freedom of movement needed for efficient swimming.

The Marlin has a proud history in competitive swimming. Earlier generations of the suit were worn by elite athletes including Faris Al Sultan, 2005 Ironman World Champion, and Christof Wandratsch, who set the then-world record for the fastest English Channel swim in 2005. This latest generation takes that proven foundation and combines it with modern materials, construction techniques and hydrodynamic technology.

Engineered Around the Female Form

The Marlin Women's Triathlon Wetsuit has been independently designed and cut to complement the female body, helping create a smooth, streamlined fit across the shoulders, torso, hips and legs.

Available in XS, S, M, L, XL and XXL, the suit is designed to feel like a second skin: close enough to minimise water movement between the suit and body, while allowing the flexibility required for a natural swimming stroke.

Advanced Yamamoto Neoprene & SCS

The Marlin combines Yamamoto #39 and #40 neoprene with Super Composite Skin (SCS) coating to create a lightweight, flexible and hydrodynamic suit.

Highly flexible Yamamoto #40 is strategically used across the arms, shoulders, back and ankle sections, where unrestricted movement is essential. The remaining panels use lightweight and soft #39 neoprene to provide a comfortable balance of flexibility, insulation and performance.

The smooth SCS outer surface is designed to reduce water resistance while also helping the suit glide more easily over the body during dressing and removal.

Aerodome Buoyancy Technology

At the heart of the Marlin is a 5.0mm Aerodome core panel, extending from the knees across the front of the thighs and wrapping around the hips, buttocks and lower abdomen.

Aerodome uses evenly positioned air pockets within the neoprene to increase buoyancy while reducing material weight. In the Marlin, this buoyancy is concentrated around the lower body to help raise the hips and legs in the water, supporting a more efficient body position and encouraging natural hip rotation through the stroke.

Ti-Alpha Thermal Protection

For cold-water performance, the torso and calf sections incorporate Ti-Alpha, a titanium alloy layer positioned between the neoprene and inner lining.

Designed to reflect body heat back towards the swimmer, Ti-Alpha helps reduce heat loss and improve thermal insulation in colder open-water conditions. The technology is particularly valuable across the torso, while the calf panels provide an additional layer of thermal protection.

Designed for Faster Transitions

Triathlon racing demands more than speed in the water. The Marlin has therefore been designed with quick and practical removal in mind.

Instead of conventional elastic wrist cuffs, the forearm and lower calf openings feature long-taped internal seams that can be trimmed to suit the individual swimmer. Combined with flexible 2.0mm Yamamoto #40 neoprene in these areas, the suit can be pulled over the hands and heels more easily, helping reduce transition time and frustration.

A YKK® zip with long puller, Velcro fastening and protective inner zip flap completes the race-ready design.

Built for Open Water

Bright purple shoulder and arm panels provide increased visibility in open water, while the carefully considered panel construction supports freedom of movement, buoyancy and thermal protection where they're needed most.

Whether you're training in the open water, preparing for your first triathlon or chasing your next personal best, the Marlin Women's Triathlon Wetsuit combines Northern Diver's heritage with modern performance technology to help you swim with confidence.

From the original Marlin to today's advanced triathlon suit, this is 45+ years of wetsuit expertise built around the modern female swimmer.

KEY FEATURES

1. Female-Specific Fit

Designed and cut specifically around the female body shape, the Marlin provides a close, second-skin fit designed to minimise excess movement while maintaining the flexibility required for an efficient swimming stroke.

2. Yamamoto #39 & #40 Neoprene

The suit combines lightweight Yamamoto #39 with highly flexible #40 neoprene. #40 is strategically positioned through the arms, shoulders, back and ankles to maximise freedom of movement during the stroke.

3. Super Composite Skin (SCS)

The smooth SCS coating creates a hydrodynamic outer surface designed to reduce water resistance. It also helps the wetsuit slide more easily over the body, making it easier to put on and remove.

4. 5.0mm Aerodome Core

A buoyant 5.0mm Aerodome panel extends from the knees across the thighs and around the hips, buttocks and lower abdomen. Its integrated air pockets increase buoyancy and help lift the lower body into a more efficient swimming position.

5. Ti-Alpha Thermal Technology

A titanium alloy Ti-Alpha layer is incorporated into the torso and calf sections to help reflect body heat back towards the swimmer, improving thermal insulation for colder open-water swimming.

6. Swim-Roll Body Position

The Marlin's strategically varied neoprene thicknesses are designed to support a natural swim-roll technique. Increased buoyancy around the hips and legs helps encourage a streamlined body position while allowing natural rotation through the stroke.

7. Trimmable Cuffs & Calves

Long-taped internal seams allow the forearm and lower calf openings to be trimmed to the swimmer's preferred length. This allows for a more personalised fit and easier removal during triathlon transitions.

8. Flexible 2.0mm Quick-Release Sections

The cuffs and lower calf sections use highly flexible 2.0mm #40 neoprene, helping the suit slide more easily over the hands and heels when dressing and removing the wetsuit.

9. Race-Ready Construction

Triple glued and taped seams provide a secure and durable construction, while the YKK® zip, long puller, Velcro fastening and protective inner zip flap provide practical performance for training and race day.

10. Open-Water Visibility & Personalisation

Bright purple shoulder and arm panels increase visibility in open-water environments. The suit can also be personalised with names, logos and other approved designs through Northern Diver's in-house design team.
