Frequently Asked Questions
Everything you need to know about AONIJIE technical sports gear and your order.
How do I choose the correct size for my hydration vest?
AONIJIE hydration vests are designed for a snug, 'no-bounce' fit. We recommend measuring your chest circumference while wearing your typical running gear and referring to the specific size chart on the product page. Many of our vests feature adjustable side straps for a customized fit.
Are your hydration bladders and soft flasks BPA-free?
Yes, all AONIJIE hydration solutions, including our PEVA bladders and TPU soft flasks, are 100% BPA and PVC-free. They are food-grade safe and designed to be odorless and leak-proof during high-intensity activities.
How long does international shipping take?
Orders are typically processed within 1-2 business days. Depending on your location, standard international shipping usually takes between 7 to 15 business days. You will receive a tracking number via email as soon as your package is dispatched.
What is your return policy for performance gear?
We offer a 30-day return policy for unused items in their original packaging with tags attached. Due to hygiene reasons, hydration accessories like bite valves cannot be returned once the seal is broken unless there is a manufacturing defect.
How should I clean and maintain my AONIJIE backpack?
To preserve the technical fabrics and sweat-wicking properties, we recommend hand washing in cold water with a mild detergent. Avoid machine washing, bleaching, or tumble drying. Always air dry in a shaded area away from direct sunlight.
Do you offer a warranty on your sports equipment?
Yes, we provide a 12-month limited warranty on all AONIJIE products against manufacturing defects in materials and workmanship. This does not cover damage caused by normal wear and tear, accidents, or improper use.
