Overview

Please add this service to your cart if you need alterations. 

  • All alterations are done by Sirensong's owner/designer, Jamie, in our Hawaii workshop.  As such, please keep in mind that adding alterations adds time to the date you will receive your wetsuit.  If you have a quickly approaching deadline (e.g., leaving for a trip), please check with Jamie to confirm whether it is possible to meet your deadline.  
  • We recommend that you check with us first to see which option best describes your project if you aren't sure.  Note that if you want multiple alterations listed as options here, you don't need to add each to the cart - please choose whichever of the alterations you need is most expensive and we'll use that labor charge to cover everything you need done. 

Confused?  Feel free to email us your questions! 

Mahalo!

International Taxes & Tariffs

flags

For our valued INTERNATIONAL customers, please take note of the following Customs Advisory...

  • International customers may be responsible for any import taxes, duties, or tariffs assessed-by & payable-to your home country.
  • Customs processing time often adds unpredictability to the expected delivery date for international shipments.
  • After your package has shipped, we will upload copies of your shipping documentation to your order status page Sign in to your account, or see your Order Confirmation Email for link, which you can provide to Customs if they request it.
Standard International Flat-Rate Shipping — $24

Service generally takes 8–15+ business days. 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.

Order Flow...

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

  • Orders containing hats, including grab-bags, 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 aware 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 expedite the process on our end.

All of our shipping options include package tracking. Choose from our discounted flat-rates (USPS Priority Mail) to save money, or select a courier service (FedEx/UPS/DHL) to get your package faster and enjoy enhanced package tracking.

  • 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 shipper. Not to worry...updates should appear soon!

Store Policies (Returns, Refunds, Etc.)

Our Goal is to Run this Business with Aloha,
Always.

We get it...online wetsuit shopping can be difficult. It’s disappointing for you when something goes wrong, and it’s disappointing for us too! Please rest assured that if anything does go wrong, we will do our very best to make it right! As a small business, each & every customer is meaningful to us. YOUR HAPPINESS MATTERS! Ultimately, your satisfaction is our top priority.

EXCHANGES

If the size/fit/color/*whatever* is incompatible, we will happily do an exchange on eligible items. If you want to exchange for a lesser-price item, no problem — we’ll refund the price difference and honor any applicable promo codes from your initial order.

Send the item back to us and once we receive it, we’ll ship the replacement wetsuit back to you. (In a rush? ...let us know and we can use the tracking number as confirmation of your return, and we’ll get the replacement suit out to you right away!)

You will not be charged for shipping of the replacement wetsuit out to you. For domestic (USA) exchanges, we will also cover the cost of you sending the original wetsuit back to us.

REFUNDS

You have up to 30 days after receipt of your order to request a refund and begin the return process. For a full refund, exchange, or store credit, your item must simply be unused and returned to us in the same condition that you received it. (Don’t worry if you have removed the tags.)

Send the item back to us and once we receive it, a credit will be applied to your original method of payment. You’ll get an email notifying you of the refund once it has been initiated. Depending on the credit card company/payment method, it can take up to 10 days for the funds/credit to show in your account.

After 30 days? No worries... we can still offer you an exchange or store credit. (We apologize for any inconvenience!)

If an item is returned to us used or notably altered from the condition in which it was sent, to an extent that it can no longer be sold at full price to a new owner, we'll contact you to discuss why a full refund/store credit or exchange can’t be offered. (Don’t worry, this is highly unlikely — we’re not trying to take advantage of anybody! At the very least, a partial refund/store credit will be issued.)

Return Instructions

  1. Please first send an email to let us know you will be returning something:
    love@sirensongwetsuits.com
  2. For exchanges within the USA, we will cover the cost of return shipments. A return label will be emailed to you, which you can print out & use to send the package back to us.

    For refunds and international exchanges, we ask that you cover return shipping costs. Let us know if we can help out by purchasing a shipping label for you (domestic only), in which case we will refund you for the merchandise (vs. merchandise + shipping). If you’d rather buy your own label, we suggest using a trackable shipping service so we can confirm shipment in the unlikely event that your package is lost in transit. Returns should be mailed to the following address:
    SIRENSONG WETSUITS
    61-274 KAMEHAMEHA HWY, UNIT G
    HALEIWA, HAWAII 96712-1300 | USA
  3. Please include your name, and if possible, your Order Number (SIR####) along with the returned merchandise so that we can properly identify it when it arrives.
  4. FOR INTERNATIONAL CUSTOMERS: If returning an item from outside the US, be sure to indicate “Returned Merchandise” on customs forms, as you should be able to recoup import tariffs/taxes you paid. You’ll need to check with your home country’s customs department to determine the exact process.
  5. It’s very important that returned merchandise be carefully and properly packed so that it does not come back to us with extra creases! Some creasing is normal/unavoidable and will relax after use, but nobody likes to receive an excessively wrinkled wettie. With that in mind, we kindly ask that you please return your suit using the following packing technique:
  1. Wetsuits should be laid out flat and placed inside the protective plastic sleeve. (Long sleeve suits come with extra airbags to reduce creasing. Fold the sleeves under to the back of the wetsuit and place the air bags in the fold between the sleeve and the back of the wetsuit. Do this before inserting the wetsuit inside the plastic sleeve.)
  2. Next, with the wetsuit already in the plastic bag, place the [remaining] air bag cushion(s) over the center-back of the suit and gently roll or fold the wetsuit over the cushion so as to avoid hard creases or folds.
  3. Please use an appropriately sized cardboard box (preferably the one your order was shipped in, if you still have it) rather than a soft packing envelope to protect the merchandise. 


These simple steps
make a huge difference!
MAHAL❤

ALTERATIONS

If you find that you need alterations to improve the fit of your suit, either before or after you have used it, please let us know! Some mods may be outside the scope of what we can offer, but others may be doable. Depending on the difficulty of the job, we generally charge between $15 and $80, or may not charge you at all.

REPAIR/WARRANTY

If a wetsuit requires repair within the first year — ugh, we’re SO sorry! — Quality and craftsmanship is deeply important to us! Sirensong will make the repair for free and will cover all associated costs. We can also reimburse you if you prefer to have it repaired locally. Repairs are also possible after one year, but we may charge a small labor fee and ask that you cover shipping costs.

Drop Us A Line

Aloha! We’re happy to answer any questions you have or assist you with placing an order. Send us a message using the form below and we will get back to you as soon as possible!
