I purchase two different kind and out the two the cotton with the two button is my favorite. Be aware that that underwear run small so if you are normally a small get a medium. It’s awesome with any kind of packing you’re wearing plus the adult activities! I will be getting more!
My packer fits perfectly and I feel so sexy and manly
Paired this with the Axolom Noodie. They were comfortable and packed well, but the hole was high up and caused STP leakage.
It takes a little while to get used to the STP but it’s amazing. Great quality and design.
They are very comfortable and they hold the packer still
First STP I could successfully use with no leaks!
So far im so happy with my purchase. Came in about a week. Its very easy to use and feels and looks great. I chose the color pretty spot on. Thank you so much!
I was not expecting to get as much from this as I do. In terms of StP I am still learning, but it is very comfortable and has taken the place of my daily packer. I use the flex fit harness and once it warms up to my body temp, it really starts to feel like a part of me.
There are a few draw backs, if you're not careful packing, there will be some popping/snapping from the cup. If you pack straight down, the bulge can be square without rearranging. Since this is the first StP I have ever been successful using for the tP part, I'm not sure if the learning curve is standard. The cup does seem on the smaller side which makes it good for long term comfortable wear, but very little margin of error when it comes to positioning. Despite it being very flexible and comfortable it is still pretty springy and if you're not careful there is still the potential for the dreaded bonery appearance.
For those wondering I am 5' 3" and 136lbs and I think this is a fantastic choice for smaller dudes looking for a more discrete bulge.
AXOLOM Au Naturel FTM Packer -- 4.3" Shaft Circumcised
the anti-spillage lip could be wider, it takes some practice to use the STP side of it but overall it looks very nice and does the work well as a packer too.
