Frequently Asked Questions
Everything you need to know about your Silix performance gear.
How do I know which size to order for my athletic wear?
Each product page includes a detailed size guide with specific measurements. If you are between sizes, we recommend sizing up for a relaxed fit or sizing down for a compression fit.
What is Silix's return policy on used sports equipment?
We offer a 30-day return policy for items in original, unused condition with tags attached. For hygiene reasons, base layers and swimwear cannot be returned once the seal is broken.
How long does shipping take for domestic orders?
Standard shipping typically takes 3-5 business days. We also offer expedited 2-day shipping at checkout for athletes who need their gear in a hurry.
Are Silix fabrics moisture-wicking and squat-proof?
Yes, our apparel is engineered with advanced moisture-wicking technology to keep you dry and high-density knit patterns to ensure 100% opacity during intense workouts.
Do you offer international shipping?
Silix currently ships to over 50 countries worldwide. Shipping costs and delivery timelines vary by location and are calculated at the final stage of checkout.
How should I care for my high-performance gear?
To maintain fabric elasticity and sweat-wicking properties, we recommend machine washing in cold water with similar colors and air drying. Avoid using fabric softeners or bleach.
