The Sirensong Surf hat features a leash that you can tie on to your bikini or wetsuit so you won't lose the hat in the surf or wind. Available in a variety of colors with screen-printed and/or fabric embellishments on the brim.
We have a taller 'high-rise' option which is more like a traditional "trucker" style cap, and a low-rise version, which is closer in style to a traditional baseball cap.
Each hat is custom-decorated in our workshop prior to shipping, so please leave a note at checkout if you have any specific request for hat decoration - otherwise, we're happy to surprise you! Note that hats may take an extra day or so to ship due to the custom-nature of the designs.
Our Premium Ready-to-Wear collections are made with luxuriously soft and supple limestone-based Yamamoto Neoprene (2.5 mm thick) and high-quality, 4-way stretch Lycra fabric. Together with our exceptionally tailored design, these materials provide added stretch and a more flexible, forgiving fit than other wetsuits of comparable thickness that you may be used to.
What's more...our signature side-ties allow for greater variance in bottom sizing: cinch tighter or loosen as needed for a more customized fit

It is important to remember that every woman's body is different, and our wetsuits stretch in subtle ways to fit differently based on height and weight distribution as well as specific measurements.

- The cm ranges presented above estimate the minimum and maximum body measurements expected to comfortably fit in a given size, and are based on actual wetsuit measurements and stretch capacity.
- For example, with the XS Bust range of 73-85 cm: 73 cm is just slightly larger than the actual wetsuit measurement (you want it to stretch for a snug fit), and 85 cm is at the upper end of the materials' stretch capacity.
- For an optimal fit, your measurements should be somewhere within the given range, but larger measurements may still fit if you are smaller in other areas.
- Taller ladies or those with a long torso who fall in the XS or Medium category may want to choose a larger size to accommodate additional height. Our jackets provide an option for those with a hard time fitting in a 1-piece suit. We look forward to adding XL springsuits and additional tall sizes in future collections!
If you have additional questions, you can email us and we'll help you pick the best fit.
Mahalo!
