What is the point of wearing FAST helmets if you are not going to wear tactical headsets. You sacrifice some level of protection in order to better integrate comtacs.
I am starting to see more non special forces PLA soldiers wear them. Aesthetically, it does not look good wearing them without headsets.
Have you worn them all day?
1. It saves battery on your ear pros
2. Two gel pads pressed up on the side of your head in the jungle get pretty hot after a while.
3. You only really wear your Peltors when you are expecting contact.
Most troops would rather not wear a helmet if they can get away with it especially in a hot and/or humid environment. I still remember having to wear the old PASGT years ago and how heavy, uncomfortable and unstable it was. (2 point chinstrap, no nape support at all). The LWH and MICH/ACH are noticeability lighter, much more comfortable (with the right pads, issued pads from Gentex are very hard and not comfortable at all) and more stable with a 3 point chinstrap. Even without ear pro, I'd take a FAST helmet over a MICH anyday. Less material means less weight, better situational awareness too since the extra ballistic material can actually muffle your hearing slightly. I personally can care less about aesthetics if I am wearing something that makes me more efficient in my duties, even if its a small amount.
I have several different electronic ear pro sets and tend to wear them all day out in the desert when shooting. All of them have the uncomfortable stock ear cups replaced with gel cups which make a huge difference. Even when its over 100 F out, I wear them no problem. Batteries last a long time too, only exception is my Peltor Tac 500s which have Bluetooth anyway.
Only exception is that since COVID, I've been wearing neck gaitors not really for virus protection (I rarely if ever get sick) but for sun protection. (I burn easily and Im tired of sunscreen everyday) Since the gel cups have to seal over bunched up cloth instead of skin, it can get uncomfortable.
