Frequently Asked Questions
Everything you need to know about your SEFI performance gear.
How should I care for my SEFI activewear?
To maintain the technical integrity of our fabrics, we recommend machine washing on a cold, gentle cycle with similar colors. Avoid fabric softeners and tumble dry on low heat or hang to air dry.
What is your return policy for sports equipment?
We offer a 30-day return policy for all unworn apparel with original tags and unused equipment in its original packaging. Please note that for hygiene reasons, water bottles and sweatbands are final sale.
Do you offer international shipping?
Yes, SEFI ships worldwide. Delivery times vary by location, typically ranging from 5-10 business days for international orders. Shipping costs are calculated at checkout based on your destination.
How do I know which size to order?
Each product page features a detailed 'Size Guide' with specific measurements. Our athletic wear is designed for a compressive fit; if you prefer a more relaxed feel, we recommend sizing up.
Can I change or cancel my order after it's placed?
Because we aim to process orders as quickly as possible, changes or cancellations can only be made within 60 minutes of purchase. Please contact our support team immediately for assistance.
Are your materials sustainably sourced?
At SEFI, we are committed to performance and the planet. Many of our collections utilize recycled nylon and organic cotton to reduce our environmental footprint without compromising on durability.
