SpareParts Pete Trunks Nylon Packing Underwear Black Size S

The SpareParts Pete Trunks are packing underwear in a short, square-cut boxer brief style, here in black, Size S. SpareParts made the Pete line for soft packing: a front pouch holds your packer securely so it gives a natural bulge, and it won’t shift, slip or fall out when you move.

The Pete Trunks look like boy shorts but have an open fly, so you can use a stand-to-pee packer. The fabric is a light nylon and spandex jersey that wicks moisture and sits smoothly under clothes.

• The base of the packer sits in its own rear panel, so it stays put.
• An extra elastic strap sewn inside the pouch adds security.
• You choose: packer straight against your skin, or fully or partly covered.
• The open fly front gives easy access and works with an STP packer.
• Works with a wide variety of packer brands, sizes and shapes, per SpareParts.

From SpareParts’ own Pete product page. SpareParts’ measurement chart isn’t in the text we could read, so we don’t list waist sizes.

The Pete line comes in four cuts. The Pete Trunks give more leg coverage, like boy shorts. The briefs are a classic contoured pouch brief with a four-inch side. The Commando is a jock-strap style, and the Freestyle adds a thin sheath over the pouch. We stock these:
