Here is what the makers have to say about Pete:

As with all SpareParts HardWear products, PETE is fully hand or machine washable, making him hygienic and easy to care for. 

PETE is made of light weight Nylon, Spandex, Jersey material. The Nylon Spandex component helps PETE breathe and to pull moisture away from your body, to keep you cool and dry. The Jersey component enables PETE to hug and hold, and be comfy soft against your skin.

PETE'S open fly front, provides easy access, and enables you to use a STP (Stand to Pee) packer naturally and with complete confidence. 
Pete doesn't want to be just a friend; he wants to be your BFFAF (Best Friend Forever And Forever). You never have to wonder, as PETE'S always got your back, your front, and everything in between. Whether you are taking wide steps, using the restroom, or performing rigorous activities, PETE'S secure fit, allows you to move freely, with zero fear that your packer will shift, dislodge or worse fall to the floor. 

PETE is agile and easy going; you can pull down and just as quickly pull up on your PETE UnderWear knowing that your packer will stay securely in place, exactly where you want it. 

PETE helps your image, as his contoured pouch under clothing, gives even a small packer the realistic bulge appearance of a flaccid penis. He is a great companion, and comfortable to wear all day along.

The sheath covers the packer so everything is nicely tucked in the pouch, and can be adjusted to sit in a comfortable position. You do have the option of the shaft sitting on the outside of the Freestyle via an opening on the side of the front.
