Frequently Asked Questions

Everything you need to know about AONIJIE performance gear.

How do I choose the right size for my hydration vest?

We recommend measuring your chest circumference while wearing your typical running apparel. Each product page includes a specific size chart to ensure a snug, bounce-free fit for your trail running needs.

Are AONIJIE water bladders and flasks BPA-free?

Yes, all AONIJIE hydration products, including our TPU water bladders and soft flasks, are 100% BPA and PVC-free, ensuring safe and odorless hydration during your workouts.

What is your return policy for sports gear?

We offer a 30-day return policy for all unused items in their original packaging. If your gear doesn't fit or meet your expectations, contact our support team to initiate a return or exchange.

How long does shipping take for international orders?

Standard international shipping typically takes 7-15 business days. Once your order is dispatched, you will receive a tracking number via email to monitor your package's progress.

How should I clean and maintain my running backpack?

To preserve the integrity of the technical fabrics, we recommend hand washing with mild soap and air drying. Avoid machine washing or tumble drying, as high heat can damage the waterproof coatings and elastic fibers.

Which payment methods do you accept?
