Frequently Asked Questions

Everything you need to know about your AONIJIE performance gear.

How do I choose the correct size for a hydration vest?

We recommend measuring your chest circumference at the widest point while wearing your typical running gear. Please refer to the specific size chart on each product page, as our vests are designed for a snug, 'no-bounce' fit.

What is the best way to clean my AONIJIE hydration bladder?

Rinse the bladder with warm water and mild soap after every use. Use a cleaning brush for the tube and let it air dry completely in an inverted position to prevent mold growth.

How long does shipping take for international orders?

Standard international shipping typically takes 7-15 business days depending on your location. Once your order is dispatched, you will receive a tracking number via email to monitor your delivery status.

What is your return policy for sports gear?

We offer a 30-day return policy for all unused items in their original packaging. Please note that for hygiene reasons, hydration flasks and bladders cannot be returned if they have been filled with water or used.

Are AONIJIE products covered by a warranty?

Yes, all AONIJIE products come with a 12-month warranty against manufacturing defects. This does not cover normal wear and tear, accidental damage, or improper care of the equipment.

Which payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, American Express), PayPal, and Apple Pay to ensure a secure and convenient checkout process.
