Billabong Women's Synergy Wetsuit Review

Looking back at Cleanline’s top-selling women’s coldwater wetsuits of the past few years, the Billabong Synergy continually is at the top. We’re not surprised at the Synergy's surge in popularity, given the eco-friendly materials and quality features. Ladies who are looking for a wetsuit that can handle a wicked Nor’Easter or a gnarly winter PNW swell can rest assured they’ll have a comfortably warm session when paddling out in the Synergy.

The Synergy is an exceptional value and performance option for your cold water surfing needs. Furthermore, its competitive price point means you get all these great features without emptying your wallet.

Highlights and Features

  • Made with premium, recycled materials
  • Strategically placed seams for a comfortable fit
  • Graphene recycler lining for incredible strength and heat

Without further ado, let’s take a look at what makes the women’s Synergy so special.

Neoprene and Liners

Billabong took it upon themselves to create a more eco-friendly means of producing neoprene. Through the use of up-cycled car tires in addition to leftover neoprene scraps, the Superlight Foam neoprene has high thermal retention along with being a surprisingly stretchable rubber. Compared to other $200-$300 wetsuits, the Superlight Foam neoprene tops out as one of the most flexible options.

By far, the key feature of the Synergy is the graphene internal liner with its funky purple honeycomb appearance. This Nobel-prize-winning material contains some mind-boggling technology: Graphene is 200 times stronger than steel but remains flexible and is an excellent conductor of heat. Once in motion, the graphene liner warms up quicker than other liners and continues to produce heat even when waiting for the next set of waves to come through.

The liner is placed where it matters most: in the chest, back, and hood. The strategic placement provides optimal warmth while still maintaining flex in the shoulders and arms for easier paddling. Billabong doesn’t boast about this, but from experience, we’ve found that the graphene liner dries quicker than other liners in competitor suits.

Seams and Stitching

The makeup of the seams and stitching is such a vital component of quality wetsuit design. Billabong incorporates its climate-friendly mentality with the use of a water-based adhesive. The seams are glued and blind stitched, which is commonly found in mid-range wetsuits.

The Synergy has strategically placed Superflex Neo Tape on the inside of the wetsuit in high-stress areas for added durability and quality. You can find the tape on the chest, back, inner thighs, and knees.

Fit and Cut

The general fit of Billabong wetsuits runs true to size with a slightly wider cut to the neoprene panels, which results in a good fit for ladies with a few curves or a more athletic build. The Synergy is available in a wide range of sizes from 2 to 12, with a little bit of flair in the design.

A key update for all Billabong wetsuits has been the redesign of the hood on the 5/4 model. For ladies with a full head of hair, we’ve found the hood to have a forgiving and comfortable fit.

Entry and Zipper

The Synergy is available in two entry systems: back zip and chest zip. Surfers who are looking for a user-friendly wetsuit should consider the back zip entry option. The large back entry makes it an ideal choice for beginners, as it offers ease when putting on and taking off. An extra panel of neoprene is layered between the zipper and your body. This design feature helps to quickly flush out any water without making direct contact with the skin. The water simply flushes back out thru two small drain holes along the lower back.

The Synergy’s slant chest zip entry offers superior water protection and performance. The smaller chest zip entry helps to reduce water infiltration, allowing you to stay drier for longer. Additionally, the tighter seal minimizes water flushing. Moreover, because a smaller opening requires less material, it also allows for better stretch capability throughout the suit as well as greater flexibility while surfing.

When it comes to performance, the Synergy wetsuit is designed to keep you warm and comfortable in the water. With the graphene-lined interior trapping heat and offering superior insulation, you stay warm for longer. The seams are also internally taped for extra comfort, with no irritation or chafing.

Furthermore, the suit is made from eco-friendly neoprene, which is soft against the skin and gentle on the environment. Additionally, it flexes easily with your movement, providing an unrestricted range of motion in the water. With its unique combination of features, the Billabong Synergy is ready for anything.

Value and Durability

As the cost of quality gear increases, the Synergy remains an affordable option. Topping out at $300 for the 5/4 hooded model, it’s tough to find a comparable option to the Synergy with high-tech options like the Graphene liner.

With proper care and treatment, the Synergy has proven to hold up well against salty ocean water. Our warranty guru can attest to the fact that it’s very rare to see the suit come back for warranty issues.
