The Utility STP Packer is made from thin, soft platinum silicone. It is designed to be worn clipped into the included elastic waistband harness.

When not being used for standing-to-pee, the Utility STP Packer hangs with the cup folded against the body. The silicone is flexible and compressible for easy packing. To use for peeing, the cup opens up and is placed between the legs. The Utility has a generous reservoir cup and a tapered funnel to ensure good flow.

This version of the Utility STP has a 4 inch shaft length.  When open, the pee cup measures 3 inches in length and approximately 1.5 inches in width.

When folded shut the total length of the 4 inch shaft Utility STP is 8 inches, and the total folded width is 4 inches.

The included harness is adjustable, with a maximum length of 60 in. The harness is made from 1 inch black polyester elastic with an adjustable plastic slider.

The clips that hold the STP in place are plastic. The clips will leave indentation marks on your STP, but do not cause functional damage.

The Utility STP is available in three color options: light flesh tone, medium flesh tone, and dark flesh tone.
