Axolom STP Trunk 1.8" O ring is packing underwear for STP Packers. You can pack any of the Stand to Pee prosthetics. It can't be packed with FTM Soft Packers because FTM packers are soft and not eligible for this packing with STP Trunk. It looks naturally well and it is very comfortable. The Axolom STP Trunk is similar to our Axolom STP Trunk. The design is the same but the color is different.
Introduction: Packing underwear is an essential part of trans men's life. The Axolom Packing Jockstrap underwear has an "O ring band" inside for holding a packer gear and also has a little pouch for holding a FTM Packing Gear.
In the beginning, we build various soft FTM packers and some Stand to pee prosthetics. Then we thought to make some essential products such as STP underwear, and FTM packing underwear.

The boxers themselves are quite comfortable, and my STP feels very secure in them. I did have a lot of trouble getting my STP placed correctly, as the natural positioning is too high and it leaked a lot! I found some smaller sized cis boxers worked, but I did eventually get it to work with these ones too. I ordered an XS, since I have very small hips, so maybe a size up might work better?
Had to go up to an XL from a L. As you get older, things are not quite as slim as when young. XL fits great and functions great. Thanks for the product.

Does the job best packing boxers I have ever bought
I love this harness. You can pack very low with it, which is my preference.
For everyday wear, I am packing with DIY packing underwear.
I bought this harness because I wanted to be able to wear my packer without underwear on and feel naked while packing. This is perfect for that and great for wearing under boxer shorts so I can sleep in my packer.
In this photo I’m wearing the Flexit FTM Harness in Beige and the Pico Plus 2.8” (Cut version) in color C2. (I also wrote a review of that packer). I would love for Axolom to come out with more color options. This Beige has a lot of light yellow to it.
Size chart was accurate. My waist at my belly button is 36” and my hips are 37”. I wear size 32” jeans. I wear M size underwear.
I’m wearing the harness size L. It’s both snug and comfortable.
The Uno is a really good option for a slight bulge. It’s perfect for exercise shorts that tend to be tighter at the crotch. The Uno is really lightweight. So it doesn’t give the same satisfying weight as my everyday packer.
The concave form means the packer has a lot of give. So it’s great for exercising. If you lay down on your stomach, for example, you won’t feel the packer press into your pubic bone, it’ll just squish itself down.
The shaft does not come away from the balls, it’s all attached. I have the color C3.
I’m able to pack pretty low with this packer, which is my preference. I sewed a scrap of old T-shirt into my briefs to make DIY packing underwear.
I wear the Pico Plus 2.8” (Cut version) for everyday wear. I have a review on that listing too.

Hi Ezekiel,
Thank you for your feedback. We’ve contacted you via email to assist with your concern. Please kindly check your email.
Best regards,
This packer allows me to pack low and pack small. The texture feels really lifelike and makes for a great prosthetic. They have a color that works great for my skin tone (C2).
With every other packer I've tried, the packer is so large it feels disproportional to the rest of my body. Other packers, even ones marketed as small still make way too noticeable of a bulge in my pants. This packer feels gender-affirming where other packers made me wonder why I would want to replicate having a hard on all day.
Another issue I had with other packers was the balls being so wide that my thighs rub them when I walk, forcing me to sit the packer high up on my pubic bone. Being able to pack this packer low is so much better.
I sewed a scrap of old T-shirt into my briefs to make DIY packing underwear. I pack the shaft to the side of the balls. And I also really like wearing it in the Axolom Flexit FTM Harness. That's a great option for packing without wearing underwear.
The Pico Plus 2.8" is exactly what I've been looking for! It's the first time I've connected with a packer as mine and felt benefits from packing.
euphoria city. i love this thing - it fits super well, keeps things good and snug, and has worked excellently across activities (climbing gym, regular gym, hiking, chilling at home, chasing the dog, driving, etc etc etc etc).
