SpareParts Pete Briefs Nylon Packing Underwear | Secure, Gender-Affirming Packer Support (Sizes S–3XL)

The SpareParts Pete Briefs are the gold standard of gender-affirming packing underwear — a classic, comfortable, everyday option designed for folks who want their packer to feel secure, natural, and exactly where it should be. With a contoured, soft-packing pouch, these briefs create a smooth, natural bulge, even when using a smaller packer, making them ideal for beginners and long-time packers alike.

Made from lightweight, breathable Nylon-Spandex, Pete Briefs wick moisture, stay cool all day, and sit smoothly under clothing. The internal design gives you freedom and control, including an internal stability strap for extra security, the option for skin-on-skin contact, and compatibility with a wide range of packers — including STP packers for natural, confident use.

Whether you’re running errands, working out, traveling, or just moving through your day, these briefs keep your packer secure, comfortable, and exactly where you want it, with zero shifting and zero stress.
