First off, I am a bigger guy, so I needed something to fit my waist and hips. The XL-2xl I bought is actually a bit loose for me, so I am sizing down one on my next purchase so it fits more snugly. I love the feel of my packer when I wear loose boxers with this harness. It's so liberating! I can totally understand why some cis guys only wear boxers. I tend to wear boxer briefs with my packer tucked in between the front flaps, but I have been looking to find something more stable to keep me from having to adjust so many times a day. This is, by far, the best harness I have tried. The last one I had, the packer hole was down too far and it made it go down my leg. Not the best look- not very natural feeling, either. This harness doesn't chafe (it'svery soft), washes well in the washer ( I use a bag for delicates and use the delicate cycle), and keeps everything securely in place. For reference, I use a medium or large Mr. Limpy, and the hole in front works perfectly for it.
I love the soft fabric of this strap, and appreciate that it's easily washable (which I've only done by hand, not by machine). I use it mostly as a play harness, often doubling it up with a boxer harness for extra stability. With a play schlong that has a smaller base, I use it with a neoprene stabilizer I got from RodeOh, which helps it stay in place. I do recommend this strap, and use it regularly.
For me, this strap is almost ideal. It's affordable, it feels secure on my body, and I appreciate the multiple ways a packer or dildo can be worn with it. The description says it's machine washable. I haven't tried that yet, but the tag on the item says to hand wash, and that's something I'm comfortable doing and probably will do to prolong the lifespan of the garment. It is something that will require regular washing, and I'm probably going to invest in at least one more. I prefer to have a pacing strap that I can wear underneath my clothes as opposed to one that attaches to my clothes.
The Mr Limpy XS does risk falling out if not positioned snugly against the body. This can take some adjustment but is a non issue if wearing the strap under another undergarment. I imagine that less flexible dicks or ones with a larger base would not be at risk of falling out of this harness.
I really like this harness. Its fits me perfectly and I'm not afraid to go out in public packing anymore. The only issue is the ring to hold the packer in place is too big for my packer (mr limpy) and it will slip out. But if you tuck a wad of kleenex under the shaft it doesn't really move. I like it.
