Origin Story

Sirensong Wetsuits | Designer, Jamie Defay Collins
Sirensong Wetsuits | Designer, Jamie Defay Collins

Based in Hawai'i, on the North Shore of O’ahu, Sirensong Wetsuits was founded in 2013 by Designer & Owner, Jamie DeFay Collins.

Sirensong Wetsuits | Designer, Jamie Defay Collins

What began as a personal project, quickly blossomed into a full-fledged business catering to a worldwide community of women seeking flattering & functional warmth in the water.

In the beginning, all wetsuits were custom designed & sewn in-house, with patterns screen-printed or hand-painted onto the neoprene.

Now, quality production is provided by an outside group of highly skilled individuals, while all styles & fabric designs are still designed in-house.

We've also leveled-up the value & quality of our springsuits — using premium eco‑conscious limestone-based neoprene.

We pride ourselves on impeccable quality, comfortable fit, and creating the most uniquely beautiful wetsuits around.

Finally, a wetsuit you'll GENUINELY want to wear!

EXPERIENCE THE PERFECT FIT

Feminine, Flattering, and Sooooo Luxurious!

Our wetsuits were designed and tested by a woman, with careful consideration of a woman's needs, & in celebration of the female form...

Bootyliscious Options!

Choose from two flattering bottom styles that hug your curves in all the right places...

Adjustable Side-Ties

Feminine styling with a purpose! Cinch tight or loosen the side-ties to suit your particular shape & find your perfect fit.

*

Not sure if you'll like the ties hanging down? No worries! Thread them back up & through the holes to keep them tucked out of sight.

Built for Comfort

Our sleeveless wetties have deep-cut arm holes to prevent chafing, while our longsleeve suits are designed for maximum comfort when your arms are raised and moving around...

After all, you'll be doing much more than just sitting-pretty in your suit (but if that's your jam... you'll be well suited for that too!)

Either way — we firmly believe that Comfort, Functionality, & Mobility are essential!

Hourglass Shaping

Color blocking & strategic cuts accentuate — or give the illusion of — killer curves!

Order Flow

Prior to shipping, each wetsuit goes through a hands-on finishing process, followed by a thorough quality-control inspection. Orders are generally shipped from our home-base in Hawaii, within 1-2 business days.

  • Grab-Bags and other orders containing hats may take an extra day or two, as the hats are generally not finished in advance of ordering.
  • Occasionally, during high volume sales periods/sale events, it may take longer than 1-2 days to get your order out. If you have a shipping deadline we should be mindful of (e.g., leaving for a trip, a birthday, etc.) – please let us know in your order comments or by email, and we will do our best to make sure your package arrives on time.

Once your order is packed-up and ready to ship, you will receive an email containing package tracking details.

  • Because we create shipping labels online, your shipping notification email may arrive before tracking details are updated online by the shipping company (USPS, DHL, etc.) – but not to worry...updates should appear soon!

Choose from our discounted flat-rates (generally USPS Priority Mail) to save money, or pick a courier service (FedEx/DHL) for more time-sensitive service. Shipping rates are listed below:

Shipping Rates...

  • Kama'aina (all Hawaiian islands) — $6
    Once received by USPS, delivery ranges from overnight (Oahu) up to 2 business days for outer islands.
  • Overnight Express (Hawaiian islands) — $22
    While generally unnecessary on Oahu, outer-island customers requiring overnight service should choose this option. ( If you are on Oahu and require overnight service, choose this option if overnight is a MUST.)
  • Standard Domestic (Mainland, Alaska, Puerto Rico, Guam, US Virgin Islands, and APO) — $12
    This service generally takes 3–5 days, but occasionally longer, as routing overseas from Hawaii often adds extra time.
  • 2-day Express (Mainland, Alaska, Puerto Rico, Guam, US Virgin Islands, and APO) — $40
    Please note that so-called 'overnight' service from Hawaii is virtually non-existent and generally takes 2-days.
  • Standard International flat-rate shipping — $24
    Service generally takes 7–15 business days. Expect a slower Customs processing time when choosing this option.
  • International Express flat-rate shipping — $24
    Service generally takes 4–10 business days. Again, expect a slower Customs processing time when choosing this option.
  • Expedited International Express (FedEx, UPS, DHL) — Rates Vary
    This is the fastest and most reliable option with the quickest Customs processing time. Rates vary depending on location and courier service.

International Taxes & Tariffs

flags

Please be advised that you may be responsible for import taxes/tariffs, which are assessed-by and payable-to your home country's Customs agency.

  • As soon as it's available, a pdf copy of the shipping label and associated customs documentation will be available for download via a link provided on your order status page. (Please refer to your order confirmation email for the link to your order status page.)
  • Customs processing time can add unpredictability to the expected delivery date for international shipments.
