The panels are a brilliant idea but there is a brand called 2UNDR that I think does a better job with them.

The reason is because the panels keep you centered and limit movement, which is a good thing! It's nice! But after a while, you start to slide back a little and the panels start to almost push you back since they only allow for movement mostly in one direction and nothing is supporting from the back end to stop that from happening.

Here's the thing. The 2UNDR brand has a more supportive pouch system and there is a lot of support from all the angles. Really kind of holds you in place but not too much! But I was lying down on my stomach with the 2UNDER and the support on the back of the package is so good that it actually pushed the boys forward while the bed pushed them back, since I was lying on my stomach. After about 2 minutes of that position, I felt a pinch/pain and realized exactly what was happening. Honestly, it made me scared to fall asleep with them. And I imagine these, which are a less effective version of the 2UNDER system, is less likely to cause such a sensation since it doesn't support from the back end nearly as well.

So it's hard to say! Gotta pick your battles, right? I'm going with 2UNDER but I sleep with different underwear. However, they have a version called Nightshift which is a bit more relaxed overall and that might be something I can sleep in comfortably.

Hope my thoughts help. This underwear innovation is definitely something worth trying! Easily a life and game changer. Rarely do I have to adjust anything now and it's very hard to find such underwear. Didn't believe it was possible, to be real with you. Until now....
