Amazing harness

This harness works like a charm for my freely xl. I love how there's 2 holes to slide the stp through to make it even more secure. The harness hugs me well and I couldn't be happier with the purchase.

So so surprised by how well this works. I've crafted a few different versions of something similar at home to use and just can't ever get it right. The ones I've bought have been uncomfortable or didnt work well but this is super silky and comfortable, not scratchy at all. I ordered the largest size and as a 300 pound dude with about a 52 inch waist it works perfectly- I didn't want it to be too tight for all day wear but it still holds things securely once you situate them correctly.
I highly recommend this and really hope the company looks into larger sizing in the future for the folks that could use it

Amazing Product

I was initially worried about how it would feel and if it would induce dysphoria, but to my surprise, it didn't at all! When you wear it underneath your underwear, you will forget it's even there. It works amazing with a packer and keeps everything in place where it is supposed to be. The harness fits snuggly, comfortably and is completely discrete. I highly recommend buying this product if you are buying a packer from this shop.

Great Harness

Bought and use with my STP freely. It works great and is true to size, very comfortable (i forget i’m even wearing it.) Note that my personal experience (with the stp freely, i can not speak for other packers,) positioning the shaft upwards holds way better than holding downwards. Just a note! But yeah good product 👍
