Here is a guide to packing underwear. There are a whole lot of very affordable options out there. This post will tell you all you need to know about packing underwear for trans guys and FTMs.

Don’t Drop that Packer!
If you wear a packer (a phallic object in the underwear to give the appearance of having a penis – read more here), you really need to think about how you are going to keep it in place. I have heard of men who have actually had their packer fall out of their pants, and somehow survived that experience. However, I would find that extremely embarrassing. Consequently, I have spent many hours of my life fussing about what kind of underwear to wear to keep my packer firmly in place.
Good packing underwear can make your life as a trans man or FTM easier, by ensuring you feel more comfortable about passing. And also by making you feel relaxed and safe, because you know you are not going to be embarrassed by having your packer fall out of your pants!
How to Wear Your Packer
It’s really important to get the position of your packer right. It should not be worn too low or too high. Take a good look at other men’s bulges (without being obvious about it!).
Also, it helps to remember that anatomically, a penis is really just a large clit. Although it is positioned slightly more forward than a clit, if you line up the base of your packer with the base of your clit, you will have it in the correct position.
Of course, the next challenge is to keep your packer in the correct position – and that’s where underwear for packing comes in.
Regular or Custom Packing Underwear?
Basically, you can choose between regular underwear, or underwear specifically designed for packing. With regular underwear, you just want something that is going to fit tightly enough that the packer will not fall out. If the design also lends itself to working well with a packer, so much the better.

For example, a lot of people like these Scrotum Separation Cool Performance Stretch Short Boxer Briefs. These are not designed as packing underwear, but will obviously do the job just fine. Many of the customer comments attest that they do a great job of supporting a packer. Quite hilariously, the advertising copy on this product refers to the penis as a “todger”!
Enhancing Underwear Repurposed as Packing Underwear
Enhancing underwear is underwear intended to enhance the bulge of cis men. This is usually achieved by equipping the underwear with an especially designed pouch. Of course, this pouch can just as well be used to position your packer. An example is the product below: enhancing briefs.
This works very well, in my experience. Be warned however, that these are best suited for days when you want to go big! The pouch is sometimes so large and firm that you can wear it without a packer inserted!
Underwear that is Custom Designed for Packing
The problem with regular underwear is that sooner or later, you are likely to pull down your pants in a stall in a public washroom, forgetting about your packer – and have it tumble out onto the floor. Which is not at all hygienic!
If this happens while you are changing in a gym change room, it is also potentially embarrassing. I have had both of these things happen to me. In the change room situation, I snatched my packer up with such lightning speed that I was spared embarrassment, but it was NOT a fun experience!
That’s where underwear that is especially designed for packing is so great. This kind of underwear uses various designs to ensure that the packer stays in the correct position, and also cannot fall out. The simplest kind simply has a pouch at the front. The problem with this is that you may potentially wear your packer too high up.
I have a couple of pairs of underwear that work like that, and I find I don’t wear them too often as they must be worn very low on the hips in order for the packer to be in the correct position.
A Better Option
A better option is the kind that uses sewn-in extras to hold your packer. Some of them have a ring of some kind to hold the penis part of the packer in place, and some also have a cloth cage to hold the balls in place as well. In the video above, this kind of underwear is shown at minute 2:35. I have had much more success with this kind.
First, they keep the packer in the correct anatomical position as you move around, and second, they never let the packer get away. I have found that with the penis-hold-only underwear, my packer can work its way loose.
Packing Underwear that Doubles as a Harness
Some packing underwear is designed to be strong enough to double as a harness, in case you are the boy scout type who likes to be ready for anything! This dedicated packer harness is well rated by many.
Stand to Pee Packing Underwear
Also called STP packing underwear, Stand to Pee packing underwear is designed to not only keep your packer safe, but also to enable you to pee while standing, assuming you have a packer that is designed to do this. So it holds your packer securely, yet has a front opening that you can use at a urinal.
PETE UnderWear is a made-in-the-USA brand that is designed to do all this, plus be comfortable, lightweight and breathable. With this pair, you can choose to wear your packer directly against your skin, or not.
Transman-run Company for Personalized Packing Underwear
A few years ago I discovered an online supplier of underwear designed specifically for FTMs – TranZwear. This company is run by a transman, and they customize products to order. For example, you could get yourself several pairs of Dockers boxer briefs, with sewn-in cloth rings to hold your packer, and (if you wanted) sewn-in cloth loops (called ball cages) to hold your balls in place. They also have a range of brands, including Calvin Klein. Plus, they also sell packers.
I find this company very personal to deal with, and very professional too. I do not earn a commission from them – I just admire their work, and have been a repeat customer for more than a decade now. I actually recommend them to my own detriment, because I do actually earn a small commission if you choose to buy from Amazon. However, I would be doing you a disservice if I did not tell you about TranZwear.
Open Front Thong
Now for something completely different … I learned about this interesting underwear from my readers. It’s called an open front thong, and has a well-placed hole. Obviously, you can use this underwear to position a packer in the correct place, anchoring it with the penis poked through the hole. The fact that this thong costs less than a dollar means it is probably worth experimenting with!
