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

The SpareParts Pete Trunks offer a sleek, square-cut fit designed for anyone who wants secure, gender-affirming packing underwear with all-day comfort. Styled like classic boy shorts but engineered for packer support, these trunks give you a smooth, natural silhouette while keeping your packer exactly where you want it — no shifting, no slipping, no surprises.

Created exclusively for soft packing, Pete Trunks work beautifully with a wide range of packer brands, shapes, and sizes. The contoured pouch includes an internal stability strap, plus the option for your packer to rest directly against the skin for full-contact sensation or remain covered based on your preference. With an open-fly design, you can use STP packers naturally and confidently.

Made from lightweight, breathable Nylon-Spandex, these trunks wick moisture, stay cool, hug comfortably, and sit smoothly under clothing. They’re durable, hygienic, tagless, and built for everyday wear — whether you're running errands, working out, or just moving through life on your terms.
