Shipping & Returns°

Because KELVIN is in pre-sale, orders ship in waves rather than immediately. The estimates below are indicative and not guaranteed — a confirmed ship date is emailed to you before dispatch.

• Netherlands & Belgium — 1–2 business days once your wave ships.
• Rest of EU — 3–5 business days once your wave ships.
• International — 7–14 business days, customs dependent.

Shipping is calculated at checkout based on your destination. Any pre-sale shipping promotions are shown on the product page and applied automatically.

Once your wave ships, you'll receive a confirmation email with a tracking link. You can also view order status from your account at any time.

Unopened products may be returned within 14 days of delivery for a full refund. For hygiene reasons, single-use cooling elements cannot be returned once opened, except where required by law.

Email info@kelvinperformance.com with your order number and reason. We'll send a prepaid label where applicable and confirm the next steps.

Once we receive and inspect your return, refunds are issued to your original payment method within 5–10 business days. You'll get an email when the refund is on its way.

You can cancel a pre-order any time before your wave is charged and dispatched for a full refund — just email us. After dispatch, the standard returns policy applies.

If your order arrives damaged or incorrect, email us within 14 days with a photo and your order number. We'll replace it or refund you at no cost.
