Packing Underwear STP Compatible Bamboo Fabric 3-Layer Pocket

The First Step to a Secure Foundation

TRUHK boxer briefs feature a 3-layer pocket system with bamboo fabric for all-day comfort. Compatible with all Emisil packers and STP models. The O-opening design provides secure positioning for STP use.

Why It Works

  • 3-Layer Pocket: Secure positioning for packers and STP models.
  • Bamboo Fabric: Soft, breathable, and moisture-wicking.
  • STP Compatible: O-opening for stand-to-pee functionality.
  • All-Day Comfort: Designed for extended daily wear.

This piece is an anatomical model, handmade to order and designed to be worn. A few things worth knowing before you wear it for the first time.

  • Firm shaft: worn, with conditions. Pack & Play (ER) models, and 3-in-1 STP models with the support rod fitted, can be used for penetration while worn against the body — always with a condom, water-based lubricant only, and never loose or detached: there is no flared safety base. Pieces without a firm shaft are made for wear. Full conditions in section 3.4, linked below.
  • Not a toy, and not for the mouth. Keep it away from children and pets, and out of the mouth — it is not a food-contact item.
  • If it doesn't feel right, take it off. Any discomfort, irritation or skin reaction means stop wearing it and check with a doctor.
  • Not a medical device. Nothing we make is intended to treat or diagnose anything, and nothing here is medical advice.

Used outside what it is designed for, a piece can be damaged in ways that are not a manufacturing fault. Full terms, section 3.4: Product Terms & Safety.

  • Wash with warm water & mild soap after each use
  • Air-dry fully before storing
  • Store away from dust, direct sunlight & oils
  • Avoid silicone-based lubricants
  • Use cornstarch powder to maintain surface feel

I haven't even received my order. It says it's still stuck in Canada and I'm in Western Australia

Very disappointing that I haven't got my order, it hasn't moved in a while.

Great underwear!

I Would buy these over and over again if I could. I was at first bummed I couldn't get the other ones they had for sale, but I'm extremely happy with them.
