We blend 15% Royal Alpaca — the rarest grade of alpaca fiber, ultra-fine at under 18 microns — with 85% Tencel™, a silky fiber made from sustainably harvested wood pulp. Together they create underwear that naturally regulates temperature, wicks moisture, and resists odor. Both fibers are 100% natural, plastic-free, and biodegradable.
Machine wash cold on a gentle cycle with similar colors. Lay flat to dry or tumble dry on low. No bleach, no fabric softener — the fiber is naturally soft and odor-resistant, so they stay fresh longer between washes.
We offer a 90-Day Fit Guarantee. If they're not the most comfortable underwear you've ever worn, send them back for a full refund. No questions asked.
They fit true to size. The Royal Alpaca and Tencel™ blend has a natural stretch that conforms to your body without losing shape. If you're between sizes, we recommend going with your usual size — the fabric adapts.
Royal Alpaca fiber is hand-sheared once a year by fourth-generation herders in Peru, sorted by micron count, and processed at a GOTS-certified mill. Small batch production means every pair gets the attention it deserves. The 3-pack and 6-pack bundles bring the per-pair price down significantly.
Yes. Every fiber is natural — 15% Royal Alpaca and 85% Tencel™, both biodegradable. Even our waistband uses fabric-encased natural rubber instead of exposed synthetic elastics. Zero microplastics, zero polyester, zero compromise.
Both Royal Alpaca and Tencel™ are naturally durable fibers. With proper care, expect these to outlast conventional underwear significantly. The blend resists pilling, maintains its shape, and actually gets softer with each wash.
