I have a couple of older PASGT helmets that I had set up for my wife and I years ago. I recently pulled them off the shelf and installed the Oregon Aero BLSS Upgrade to them. It is night and day comfort wise. Much more comfortable and secure. I got 2 upgrade kits off of Ebay for less than $90. It took about 15 minutes for each helmet to install the kit. Unfortunately I dont have any pics as the camera is broken but here is a link to the company:
