Yes. Each item in the bundle has its own size selector. You can mix sizes freely — for example, M in Classic Cut and L in Seamless.

Bundles save between 10–30% compared to buying each piece individually — the more pieces, the bigger the discount. The exact savings are shown on each bundle page, and the discount is applied automatically at checkout.

Yes. If one piece doesn't fit, email us at support@pynpy.com within 30 days and we'll exchange just that piece — unopened and unworn. No need to return the whole set.

Most customers find 4–5 pairs is enough for a full cycle — that gives you a clean pair each day while others are drying after washing. If you prefer having extras or have longer cycles, 6–7 pairs is ideal. Bundles are the most cost-effective way to build a rotation.

Each bundle includes the underwear pieces listed on the product page plus a free waterproof travel bag. Everything ships together in one package.
