Frequently Asked Questions
Everything you need to know about your Nass performance gear.
How long does shipping take for Nass orders?
Standard shipping typically takes 3-5 business days within the continental US. International delivery times vary by location, usually ranging from 7-14 business days.
What is your return policy for athletic wear?
We offer a 30-day return policy for all unworn and unwashed items with original tags attached. Please note that for hygiene reasons, certain items like compression undergarments are final sale.
How do I find the right size for my workout gear?
Each product page features a detailed size guide. We recommend measuring your chest, waist, and hips and comparing them to our chart, as our performance fit may be more snug than casual wear.
Are Nass products sweat-wicking and squat-proof?
Yes, our apparel is engineered with high-performance moisture-wicking fabrics and high-density knits to ensure they remain opaque and comfortable during high-intensity training.
Which payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and interest-free installment plans through Klarna or Afterpay.
How should I care for my Nass technical fabrics?
To preserve the elasticity and moisture-wicking properties, we recommend machine washing in cold water with like colors and hanging to dry. Avoid using fabric softeners or bleach.
