Inspired by the haenyeo—the legendary badass women free-divers of Jeju Island—we designed this quarter-zip for navigating the treacherous waters of the corporate office. We traded the actual ocean for water cooler talk, with the lightweight bio-washed cotton jersey that breathes easy, ensuring you won't break a sweat when the edible hits right before a mandatory sync. Naturally, we equipped it with our signature stash pocket so you can safely store your goods and submerge yourself in a THC-induced corporate dissociation. It’s the ultimate stealth uniform for surviving the 9-to-5 grind.

Fit Tip: Heads up, this one is cut a little slimmer than our standard fit to sit closer to the body. Order true to size for that sleek, tailored look, or size up if you want to hit our usual roomy, relaxed drape.

⚖️ Risk of Loss (UCC § 2-509 — in human words):

Once we hand your package to USPS/UPS/FedEx and they scan it in, they are responsible for getting it to you.

We’re a small brand — we can’t absorb carrier mistakes the way Amazon can.

If you want coverage until final delivery, please add shipping protection at checkout.

Please note that Sundae School will not be liable for any lost/stolen shipments that do not have a shipping protection.

If you purchased package protection with your order and your package is lost, you can file a claim here.

⏰ FTC SHIPPING TIMING (16 CFR § 435)

We legally must ship within the time advertised — or within 30 days if nothing is stated.

If there’s a delay, we’ll notify you + give you the option to cancel for a full refund.

📦 PACKAGE PROTECTION

Your package protection covers shipping mishaps caused by carriers during transit. It is added to all orders by default, but you may remove it on the cart page before checkout. Please note that once it is removed, we're unable to assist with any shipping-related issues.

Your package protection also includes a free return label, meaning the cost of the return shipping is covered if you choose to return or exchange your order. However, it does not cover restocking fees charged by our third-party warehouse, as these are not related to shipping mishaps, nor overrides final-sale eligibility.

If your package is lost and you purchased Package Protection with your order, please file a lost package claim here.

🕵️ MISSING OR STOLEN PACKAGES

Once a package is marked “Delivered”, our delivery obligation is complete under UCC § 2-509 & § 2-510.

If it says “Delivered” but you can’t find it:

Check with neighbors/building staff
Contact the carrier to file a claim
We’ll support with any proof they need

We cannot refund, replace, or reship delivered packages.

Lost Before Delivery:

If tracking stalls or there’s no delivery scan, please contact the carrier for a “lost package” investigation.

We’ll help with documentation.

Undeliverable Packages:

Wrong address / refused / unclaimed → you cover re-shipping.

Original shipping isn’t refundable.

💸 DAMAGED / DEFECTIVE ITEMS

First of all, we’re so sorry that your item arrived in less-than-perfect condition 😭. While we don’t currently offer repair services, we’ll do our best to make this right for you.

Please email us at counselor@sundae.school with clear photos or videos of the issue, and our team will assist you as soon as possible.

Need an extra button?

Most of our garments include extra buttons inside the item. If your item did not come with extra buttons, feel free to reach out to us and we'll be happy to help.

Lost the extra buttons or your order was delivered over a month ago? You can still request replacement buttons for a small shipping fee.
