What is a Packer? A Beginner's Guide

For a lot of trans men, transmasculine and non-binary people, packing isn't a novelty or a nice-to-have. It's part of how you wake up, get dressed and walk out the door feeling like yourself. The right packer in the right underwear can take the edge off bottom dysphoria, make passing in public less stressful and shift the way you move through your own body.

The wrong setup, or no setup at all on a hard day, can do the opposite.

Despite how much packing matters, getting clear, honest information about it is harder than it should be. A lot of what's online is buried in forum threads, written for an audience that already knows the language, or trying to sell you something before it explains what it is. If you're new to packing or thinking about starting, that's a frustrating place to land.

I'm Robyn Electra, founder of Gaff and Go. Packing isn't part of my own experience as a trans woman, but it's part of daily life for so many people in our community. I've written this guide based on what we hear from the people who shop with us and what we've learned from years of designing for the trans community.

A quick note before we get into it: nothing in this post is medical advice. If you're using products that come into contact with the body, look for body-safe materials (platinum-grade silicone is the gold standard), pay attention to how your skin responds and stop using anything that causes irritation or pain. If you've got specific health concerns, talk to a healthcare provider.

SO, WHAT IS A PACKER?

A packer is a prosthetic worn in the underwear to create a bulge in the crotch area. Most packers are penis-shaped, though some are more abstract and designed for feel rather than appearance. They're worn most often by trans men, transmasculine people and non-binary people, but anyone can wear one if they want to.

The word "packer" comes from "packing," the act of placing something in your underwear to give the appearance of having a penis. People have been packing for as long as people have wanted to present masculinely without having the anatomy society expects. The rolled-up sock has a long history. Modern packers are a much more refined version of the same idea, made from body-safe silicone and shaped for realism, comfort or both.

WHY DO PEOPLE PACK?

The reasons people pack are personal and all of them are valid. Some pack to ease bottom dysphoria, the discomfort that comes from having a body that doesn't match your gender identity. For someone with dysphoria, the visual of a bulge in the pants and the physical sensation of a packer against the body can be genuinely affirming.

Some pack to pass better in public, to be read as male in everyday situations, in changing rooms, at the gym or in any setting where the absence of a bulge might feel exposing. Some pack because they like how it looks and feels under their clothes. And some pack for sex or intimacy, where the right device can be used for play or, with certain models, for penetration.

Plenty of trans-masc and non-binary people don't pack at all, or only pack sometimes. There's no rule that says you have to. Packing is a tool, not a requirement, and your relationship with it can change over time. Some people pack heavily early in transition and stop once they feel more settled. Others find it more useful as time goes on. Both are completely normal.

WHAT ARE THE DIFFERENT TYPES OF PACKERS?

There are a few different categories of packer, and the right one depends on what you want it to do.

A soft packer is the most basic and most affordable option. It's a soft, flexible prosthetic that creates a bulge in the underwear with no other functions. Soft packers are comfortable to wear all day and just need a properly fitted pair of underwear to hold them in place. If you only want the visual and the feel, this is where most people start.

A stand-to-pee packer (STP for short) is designed to let you urinate standing up. STPs have a built-in funnel that channels urine through the prosthetic, which means you can use a urinal or just stand to pee at home. There's a small learning curve, and dribbling on the first few attempts is normal, but the technique becomes second nature with practice.

A pack-pee-play packer is the most advanced category and does what the name suggests. It works as a soft packer for everyday wear, an STP for peeing standing up and a firmer prosthetic for sex with a partner or for masturbation. Some pack-pee-play models have additional features for ejaculation. These are the most expensive option but also the most versatile.

DIY packers are worth mentioning too. If you can't afford a commercial packer or aren't ready to order one (perhaps you're still in the closet or sharing a delivery address you'd rather not have packers arrive at), a rolled-up sock or a stocking-based packer can do the job. There's nothing wrong with starting here.

HOW TO CHOOSE YOUR FIRST PACKER

A few practical things to think about when you're picking your first one.

Material matters more than anything else. Look for body-safe silicone, ideally platinum-grade. Cheaper packers made from unsafe materials can cause skin irritation and break down faster. The price difference is real, but a body-safe packer that lasts for years is better value than a cheap one you replace every few months.

Size is personal. There's a real range, from small and discreet packers that just give you something to feel and a subtle bulge, through to larger packers designed for an obvious presence in fitted clothing. If you're new to packing or you don't always pass yet, smaller is often easier. A sudden noticeable bulge can draw attention you don't want. You can always size up later.

Skin tone is worth considering if realism matters to you. Most brands offer a range of tones now, though the choice is still narrower for darker skin tones than it should be.

Adhesive vs non-adhesive is the last thing to think about. Some packers stick directly to the body with adhesive. Others sit in your underwear or in a packing pouch. Adhesive packers stay in place very securely but require careful skin care. Non-adhesive packers are simpler and more flexible, but they rely on properly fitted underwear to keep them where they should be.

HOW TO WEAR A PACKER

This is where packing underwear becomes essential.

A regular pair of boxers or briefs isn't built to hold a packer in place. The packer can shift through the day, slip out the leg or settle in an awkward position, and you end up readjusting constantly. Properly designed packing underwear has a built-in front pouch that holds the packer securely against the body, where it should sit.

Our packing underwear is made from soft, breathable fabrics with a purpose-built pouch that holds a soft packer or STP in position throughout the day. The brief cut is closer-fitting than boxers, which keeps everything in place when you're moving around. 

If you'd prefer a harness, that's a valid option too. Harnesses are particularly useful for STP and pack-pee-play models, where the security and angle a harness provides matters for the prosthetic to work properly. For everyday packing with a soft packer, packing underwear is usually all you need.

WHEN PACKING ISN'T FOR YOU

A final note. Some people try packing and find it isn't right for them. The bulge doesn't feel affirming, the prosthetic feels in the way, or the practical hassle outweighs whatever benefit you'd hoped for. That's a completely valid outcome, and it doesn't make you any less trans or any less masculine.

If your dysphoria sits more in the chest than the lower body, our chest binders might be a more useful place to start. Plenty of our trans-masc readers find that binding does more for their day-to-day comfort than packing does. The two aren't mutually exclusive either, and many people use both depending on the day.

WHERE TO GO FROM HERE

Packing is one of those things you can only really learn by trying. Start with a soft packer if you're new to it, choose body-safe silicone, and pair it with proper packing underwear so you're not constantly readjusting. Once you know how it feels and how you want to use it, you can branch out into STPs or pack-pee-play models if those would help you.
