Frequently Asked Questions
Everything you need to know about your order and our products
How do I determine my correct size?
We recommend using our comprehensive Size Guide found on each product page. Our apparel is designed for a snug yet comfortable fit, so if you are between sizes, we generally suggest sizing up.
What is your return and exchange policy?
We offer a 30-day return policy on most items. Please note that for hygiene reasons, certain intimate apparel must be unworn and in its original packaging to qualify for a refund or exchange.
How long will it take for my order to arrive?
Standard shipping typically takes 5-7 business days within the continental US. Once your order ships, you will receive a tracking number via email to monitor its progress.
How should I care for my Knix products?
To maintain the integrity of our technical fabrics, we recommend machine washing on a cold, gentle cycle and hanging to dry. Avoid using bleach or fabric softeners.
Do you offer international shipping?
Yes, we ship to most countries worldwide. International shipping rates and delivery timelines are calculated at checkout based on your specific location and local customs regulations.
Are your products leak-proof?
Our specialized leak-proof collection features patented technology designed to absorb moisture and provide backup protection. Each product listing specifies the level of absorbency provided.
