Packing 101: Everything You Need to Know
From your first sock to a premium silicone packer: how packing works, how to do it, and how to find what fits your body.

Packing is one of the easiest ways to affirm your gender, and getting it right can make your days a lot more comfortable.
At Transguy Supply, our team packs every day. We've worn this stuff. Here's what we learned.
What Is Packing?
Packing means wearing a prosthetic, called a packer, in your underwear to create a natural-looking bulge. For many trans men and trans masculine people, packing reduces dysphoria and increases confidence in everyday situations: getting dressed, using public restrooms, being seen in gym clothes, intimacy.
Some people pack every day. Others only in specific situations. Some try it once and decide it's not for them. All of that is valid. Packing is a tool, not a requirement. You're not more or less trans based on whether you pack.
How Does a Packer Work?
A packer is a soft prosthetic worn in your underwear. It sits in a pouch, harness, or purpose-built packing underwear and creates a natural-looking bulge under clothing. Most packers are made from TPR or silicone and are designed to feel natural on your body. They don't attach to your skin. They're held in place by the underwear or harness.
Packers come in a range of materials, sizes, and price points. The two most common materials are TPR (thermoplastic rubber) and silicone. TPR packers like the Mr. Limpy are soft, affordable, and great for beginners. Silicone packers like the My Buddy 4" offer a more realistic weight and feel and are body-safe for long-term wear.
How to Pack: Getting Started
The basic process is simple: choose a packer, choose a way to hold it in place, and wear it. The trick is finding the combo that works for your body and your life.
- Choose your packer. Start with something cheap, like a TPR packer or even a sock, to figure out if packing is right for you before you spend more
- Choose your hold method. Packing underwear, a pouch, or a harness. Each has tradeoffs, covered below
- Position it. The packer sits in the front of your underwear, angled slightly downward for the most natural look. Most people find the right position quickly with a little experimentation
- Wear it at home first. Give yourself a few days to get comfortable with the look and feel before going out in public
- Adjust as needed. Packer size, position, and hold method are all personal. What works for someone else may not work for you
Packing With Socks: How to Pack for Free
Before spending anything, try packing with a sock. Roll a crew sock into a compact bundle, tuck it into the front of snug briefs or boxer briefs, and wear it for a day. If you hate the feeling or the look, you've lost nothing. If you love it, or it changes how you feel walking around in the world, you'll know a real packer is worth it.
The sock test is also useful if you're not sure what size packer to get. A smaller, more compact roll gives you a subtle look; a fuller roll shows you what a larger packer would feel like day-to-day.
How to pack with a sock, step by step:
- Pick a clean crew sock. A thin sock gives a subtle shape, while a thicker athletic sock adds more bulk.
- Roll it from the toe up into a short, soft cylinder, then fold the cuff over the roll so it holds together.
- For a firmer bundle, tuck the roll inside a second sock or add a few loose stitches.
- Place it low and centered in snug briefs or boxer briefs, angled slightly down, just like a packer would sit.
- Finally, check the look in a mirror with your usual pants on, and resize the roll until it feels right.

How to Choose the Right Packer
The right packer depends on your budget, the level of realism you want, your body size, and how you plan to wear it.
Budget / beginner
Start with a TPR packer like the Mr. Limpy ($20–$24). Soft, lightweight, and widely available. It's been the go-to first packer in the trans masc community for years. One thing to know: TPR contains trace mineral oil, so always use a barrier (packing underwear or a harness) instead of direct skin contact.
Best value silicone
When you're ready to upgrade, silicone is worth it. The My Buddy 4" Silicone Packer ($30) has become our fastest-selling packer. It's ultra-soft and body-safe, with a realistic weight, and it comes in multiple skin tones. The #1 Trans Packer ($38) is another strong option with exceptional detail and one of the widest skin-tone ranges in its price class.
Size
Bigger isn't always better. A packer that matches your body proportions looks and feels most natural under clothes. As a general guide: 3–4" for a subtle, everyday look or smaller frames; 4–5" for a more noticeable profile. When in doubt, start smaller. You can always size up.

How to Wear a Packer
There are three main ways to hold a packer in place. Each has tradeoffs. The best pick depends on whether you want simple, flexible, or secure.
Packing Underwear
Built-in front pouch holds your packer without any accessories. Put it on and go. The most popular method for everyday packing.
Shop Packing Underwear →Packing Pouch
Clips or pins into any underwear you already own. Good for people who want to pack in their existing underwear without buying a dedicated pair.
Shop Pouches →Packing Harness
Holds your packer firmly against your body. Great for working out, sports, or anyone who needs maximum security all day.
Shop Harnesses →O-Ring Harness
Pack in whatever underwear you already own. The O-ring holds any packer or STP device securely in place.
Shop O-Ring Harnesses →STP Packers: Pack and Pee
An STP (stand-to-pee) packer does two things: creates a natural bulge and lets you urinate standing up. If public restrooms (especially urinals) bring on dysphoria, an STP can change a lot.
Popular STP options include The Lou STP and the STP Freely XL (which pairs with an insertion rod to become a 3-in-1 device). STP packers have a learning curve with positioning, but most people get comfortable within a few uses.
For STP use, purpose-built STP underwear like the Cake Bandit STP Boxer Briefs makes positioning much more reliable than a standard pouch.

Pack and Play Packers
A pack and play packer (also called a 2-in-1 or 3-in-1) is firm enough to use for penetrative play while still soft enough to pack comfortably throughout the day. Standard soft packers aren't made for this. A pack and play is built to do both.
Entry-level options like the Mr. Right ($60) give you a firmer feel and realistic detail at a friendly price. Premium options like the ReelMagik Pack N Play ($379–$1,378) are fully customizable with hand-painted detail, floating anatomy, and adjustable firmness. It's the closest thing to a custom-made prosthetic you can get without surgery.
3-in-1 packers add STP functionality to the pack-and-play equation. The STP Freely XL + Insertion Rod ($72 bundled) is the most affordable 3-in-1 on the market. Most similar devices start at $200+.

Packing Tips for Beginners
- Start smaller than you think. Most first-time packers go too big. A smaller packer is easier to position, less likely to shift, and looks more natural under most clothing
- The underwear matters as much as the packer. A great packer in the wrong underwear will still shift and frustrate you. Invest in a dedicated pair of packing underwear before judging how a packer feels
- Wear it at home first. Give yourself a few days to find the best position and get comfortable with the look and feel before going out
- For TPR packers, always use a barrier. TPR contains mineral oil that can irritate skin with long direct contact. Always wear it with underwear or a harness between the packer and your skin
- Use packer renewing powder. A light dusting of Packer Renewing Powder after each wash keeps TPR packers soft and extends their life significantly
- Packing is personal. Some people pack every day; others occasionally. There's no minimum. Do what feels right for you
The right packer is the one you actually wear. Start simple, figure out what works for your body, and upgrade from there.
Packer Care and Maintenance
TPR packers (Mr. Limpy, Packer Gear)
- Wash with warm water and mild soap after each wear
- Pat dry completely. Never store it damp
- Dust with Packer Renewing Powder to maintain softness and prevent tackiness
- Store away from direct sunlight and away from other TPR products (they can bond together)
- Never use silicone-based lube or oil near TPR. It breaks down the material
Silicone packers (My Buddy, #1 Trans Packer, Mr. Right)
- Wash with warm water and a body-safe toy cleaning spray after each wear
- Silicone is non-porous and easy to sanitize, but it still needs regular cleaning
- Air dry completely before storing
- Finish with a light dusting of Packer Renewing Powder to restore a smooth matte finish
- Store separately. Silicone touching silicone over time can damage the surface
FAQ
How do I pack for the first time?
Start with the sock method. Roll a crew sock and tuck it into the front of snug underwear. Wear it at home for a day or two. If you like the feeling, invest in an affordable TPR packer like the Mr. Limpy and a pair of packing underwear. That combination is the simplest, most reliable starting point. Don't overthink it. You'll get the hang of positioning fast.
How does a packer stay in place?
Packers are held in place by the underwear or harness you wear them with. They don't attach to skin. Purpose-built packing underwear with a built-in front pouch is the most reliable method for everyday packing. Packing pouches and harnesses offer more flexibility if you want to pack in underwear you already own. A loose regular brief won't hold a packer well. Snug is key.
What size packer should I get?
Most beginners go too big. A 3–4" packer looks natural under most clothing and is easier to position and keep in place than a larger one. Go with 4–5" if you specifically want a more visible profile. The sock test helps here. Try different roll sizes to get a sense of what feels proportionate on your body before buying.
Can I pack with socks?
Yes, and it's the best way to try packing before spending any money. Roll a crew sock into a compact bundle and tuck it into snug underwear. It won't look as realistic as a silicone packer but it gives you the experience of packing to help you decide if it's right for you. If you want something more realistic on a tight budget, check out our DIY packer guide.
What's the difference between a packer and an STP?
A standard packer is designed for wearing (creating a bulge) only. An STP (stand-to-pee) packer does that plus lets you urinate standing up. It has a funnel system built in or attached. STPs have a learning curve with positioning but can significantly reduce restroom-related dysphoria. Some devices are 3-in-1: pack, stand to pee, and use for play.
What is a pack and play packer?
A pack and play (or 2-in-1) packer is firm enough for penetrative use while still soft enough to wear comfortably throughout the day. Standard soft packers aren't made for this. They're too floppy. Pack and play packers are built to be firm enough for play and soft enough to pack. Options range from the affordable Mr. Right ($60) to premium custom prosthetics like the ReelMagik Pack N Play.
Is it safe to pack every day?
Yes, with a few basics: use a barrier between a TPR packer and your skin (packing underwear or harness), clean your packer regularly, and rotate your packing underwear like any other underwear. Some people pack daily for years without issues. If you notice skin irritation, take a break and check whether your packer material may be causing a reaction.
