Frequently Asked Questions
Everything you need to know about SIXS performance gear, shipping, and returns.
What makes SIXS sports technology different from standard compression gear?
SIXS utilizes patented carbon undergarment technology designed to manage sweat and heat efficiently. Our fabrics transfer moisture away from the skin to the exterior of the fabric without absorbing it, keeping your body temperature regulated during intense physical activity.
How long does shipping take and can I track my order?
Standard shipping typically takes 3-5 business days within the continental US. Once your order is processed, you will receive an email with a tracking number to monitor your package in real-time.
What is your return policy for worn athletic apparel?
For hygiene reasons, we only accept returns on items that are unworn, unwashed, and in their original packaging with tags attached. You have 30 days from the date of delivery to initiate a return through our online portal.
How should I care for my SIXS gear to ensure longevity?
To maintain the integrity of the carbon fibers, we recommend machine washing in cold water on a delicate cycle. Avoid using fabric softeners or bleach, and always air dry. Do not tumble dry or iron your SIXS products.
Do you offer international shipping?
Yes, we ship to over 50 countries worldwide. International shipping rates and delivery times vary by location and will be calculated at checkout. Please note that customs duties may apply depending on your country's regulations.
Which payment methods do you accept?
