Wetsuits designed for freshwater swimming.

Ruby Fresh are Open Water Swim wetsuits expressly designed for swimming in fresh water where the need for greater buoyancy, warmth and visibility are heightened. Backed by the swim event The Ruby Swim, itself a creation inspired by the amazing geographical location with the existence of an island to swim around - all set in pristine alpine waters.

The Need

Most, if not all triathlon and open water swim wetsuits, are designed based on use in salt water, and predominantly, warmer water.

Ruby Fresh wetsuits - the 'Flow' male & female are designed around the needs of fresh water i.e. lesser buoyancy and for predominantly cooler waters, and added to this, such is the nature of open water swimming - it’s also important to be seen.

So the three points of difference are: Buoyancy • Warmth • Visibility

The wetsuit combines these three separate attributes not previously seen together in this product space.

The suits are designed to enhance body position in the water, the 'downhill' swim position feeling; enhance comfort in colder water - to keep you warmer for longer or to increase swim duration; and to be seen - additional safety in a multi-user environment.

The first suits hit the shores of New Zealand on January 8th, 2019.

The points of difference.


• Improved buoyancy for freshwater use rather than salt water use - introducing the ‘Buoyancy Tray’. • Yamamoto Ti-Alpha Titanium layers. Warmth. Thin. Light. • Open Water visibility. Gold and day-glo graphics. • Improved arm maneuverability. • Body core stabilisation. Swim-Roll dynamics. Enhancing how open water swimmers ought to swim. • Easy on. Easy off - ease frustration. Especially for older swimmers.

The suit is targeted for mid range ability swimmers and upwards. As a triathlon wetsuit it has shown to be fast in competition due to the buoyancy profile creating an improved streamlined position in the water. It adheres to FINA (Fédération Internationale de Natation) rules.

A prime requirement of the design is to enhance the 'feeling' you are swimming well. This is as important as 'actually' swimming well. Creating the streamlined body position by altering the swimmers position in the water, combined with the extremely maneuverable arms (which has been the single biggest point of feedback) - this all adds to the intended overall improved user experience.

Panel Design

Yamamoto #39 & #40 with SCS coating is used across the entire wetsuit.

Yamamoto #40 1.5mm neoprene is used throughout the entire arm / shoulder / latissimus dorsi sections (panels 3, 5, 9 & 11). It has excellent modulus, features a strong skin surface and flexibility and is the most stretchable neoprene on the market. Such extensive use of #40 grade is not 'normally' used.

The torso section of the suit, waist up, is lined with thermal Ti-Alpha, a titanium layer between the outer neoprene and the lining reflecting 35-40% of generated body heat back towards the body and the thin water layer between the body and suit lining, rather than being dissipated immediately to the water. In addition the calf panel (panel 8) also benefits from a Ti-Alpha layer in an effort to reduce calf cramping in conjunction with its 2mm width to enable easy removal when you are in a hurry!.

The one-piece core panel section (panel 1) is designed to be very buoyant in specific positions. The entire panel uses 5mm Aerodome Yamamoto SCS Neoprene which is 20-30% more buoyant than non-aerodome neoprene material. It is active from below the knee, the entire front thigh, wrapping entirely the hips, buttocks and lower abdomen. The positioning lifts the hips and legs noticeably and promotes hip roll. The panel incorporates a central chest 'pivot' section to the neck cuff. Its width is gauged to provide less buoyancy to the sternum region in conjunction with the 3mm chest panels (panel 2). This is to further aid the 'downhill' body position, in conjunction with the raised hips/legs. We term this entire panel the 'Buoyancy Tray'. The rest of the suit uses #39 grade which is lightweight and soft. The rear of the thigh (panel 7) is 4mm. All panels use Yamamoto 'SCS' (Super Composite Skin) proprietary hydrophobic coating.

Overall, the wetsuits' neoprene panel positioning promotes the more efficient swim-roll dynamics technique rather than a flat swim positioning. This technique enhances reach and creates an improved power phase in conjunction with hip roll movement.

...at base of the zipper - to aid closing your wet suit. Grab the Tab with one hand, pull up the zip cord with the other. It's genius. And it provides a clean alternative to secure your Tow Buoy.

The Original Design Specifications

Other Features Of The Suit Design

• No wrist-cuffs. After studying their need and function and then eliminating them.

• No internal forearm 'catch' panels - omitted by design after the realisation catch panels were almost useless and little more than a marketing gimmick.

Combined, these two design details allow the use of a very long taped seam on the inside of the forearm (duplicated on the calf leg section) which allows these sections of the suit to be cut to desired length. This enhances speed of removal in a racing situation (by cutting shorter) or to allow a better arm / lower calf fit.

The calf panel made from 2mm titanium lined #39 grade neoprene allows very quick and easy removal over the heel. Better than elastic stretch panels that were trialed. This is great for T1 times in Tri races but also too for those with difficulty reaching that area of the body. This can be quite an issue for some.

We have a verified Yamamoto Code of Authenticity.

Water Quality and Environmental Stewardship

Ruby Fresh wetsuits and The Ruby Swim co-founded a direct action lake and water focused initiative called The Touchstone Project.

People are reminded of the ‘Check Clean Dry’ philosophy to stop the cross contamination of lakes from ‘Lake snow’ (Lindavia) and Didymo. 

The Touchstone Project is a direct action initiative to support those concerned about the Lake Wanaka water catchment, raise awareness of impacts around the lake, and how people can have a positive influence on the water in the lake. For instance a persons personal contribution in how to minimise bad stormwater and runoff.

By working with people who 'do stuff ' - those making tangible differences, and by starting to gather and understand information about what affects lake water, Touchstone supports actions that directly improve lake values.
