I use the HHS ultra lite it is easy to put on and adjust, They do ride up in the groin area at times. And I put my jacket over top of it. Most of time I don't even know it is on. And make sure you are attached to the tree the entire time you leave ground. I know a lot of people that will no attach to the tree until they are up in the tree. I think many accidents would happen going up and down the tree.
I posted a fanboy post over in the BHOD forum about me and my buddy both buying the HSS harnesses like current Hollywood movie star Justin Zarr wears. LOL! We were both texting the whole hunt about how miserable and uncomfortable they were to us. He immediately bought a Muddy and loves it. He and his wife go to Vegas for a week and he tells me to try his Muddy while he was gone. Really comfortable and easy on and off but I don't trust those clasps it uses. Don't know what they're called but they're on everything. I could take a deep breath and the one across my chest would come undone. I knew the same buckles were on the legs as well. Hunted with it once. I went with a Gorilla. Super comfortable and I picked up two pockets as well. It may possibly take an extra 15-30 seconds to put on because you have to think to buckle the legs, but they will not unbuckle unintentionally.
