Frequently Asked Questions
Everything you need to know about the world's most comfortable underwear.
What makes BN3TH underwear different from other brands?
Our patented MyPakage Pouch Technology™ provides a 3-dimensional pouch that offers unparalleled support and comfort, keeping everything in place without the need for shifting or adjusting.
How do I find the right size for me?
We recommend checking our comprehensive Size Guide located on each product page. Our underwear is designed for a snug yet comfortable fit; if you are between sizes, we typically suggest sizing up.
What is your return and exchange policy?
We offer a 30-day comfort guarantee. If you aren't completely satisfied with your first pair, you can return them for a full refund or exchange. For hygiene reasons, subsequent purchases must be unopened in original packaging.
How should I care for my BN3TH products to ensure they last?
To maintain the integrity of the fabric and technology, we recommend machine washing on a cold, gentle cycle and hanging to dry. Avoid bleach, ironing, and fabric softeners.
How long does shipping take and do you ship internationally?
Standard shipping typically takes 3-7 business days within North America. We do offer international shipping to select countries; delivery times and rates will be calculated at checkout.
What materials are used in your products?
We prioritize high-quality, sustainable materials like Tencel™ Modal, which is breathable, moisture-wicking, and shrink-resistant, ensuring a premium feel against your skin.
