So I'm currently an OPFOR guy down here at JRTC. One cool perk about the job is we are authorized to utilize PT and other "bump" type helmets for just about everything except for actual ballistic applications. Considering MILES gear and blanks is typically the order of the day, this means that 90% of the year I wear a ballcap, but the rest of the time I'm wearing a Pro Tec. Typically the PT helmets will only be utilized for operating military vehicles, and primarily, (more importantly), for mounting NODS when we are replicating near peer threats against the rotational training units.
I LOVE being able to wear a bump helmet opposed to an ACH, it's lighter, cooler, you name it. HOWEVER, there are some major drawbacks.
Pros of a stock PT Helmet:
-Light Weight (this cannot be overstated)
-Cool (again, JRTC, it's fuckin' hot down here)
-Padding is not the best, sits real high on the head with stock pads leaving no room for beanies/6th principle of patrolling, etc....
-Issued base plates do not fit properly or securely, allowing NODs to rotate out of whack
-Chin strap is fucking garbage
-Light weight allows NODs to pull forward, making the chin strap even more of a bitch
This is how I initially set my helmet up. I kept the stock pads and chin strap, threw on a VAS shroud, a paint job, and some morale patches and called it good. As soon as it got dark we did a patrol where we had to run NODs and I was miserable the entire time. The whole helmet slipped all over my head, resulting in hot spots and terribleness. Back to the drawing board.
The first chance I got I grabbed my old Ops core harness that I had previously used on my ACH. Turns out it fits the PT helmet just fine. VAST improvement. Over the course of the last 2 years I have also been experimenting with new pad combinations and placement. While I may be losing some protection, I gained vast amounts of comfort by replacing the top and front pads with those from an ACH. I left the rear PT pad. This allows me to run beanies, get a more comfortable and secure fit, and really maximise the ventilation.
Now that I had finally figured out the best pad/harness combo, my next two issues were my paint job and a counterweight. For whatever scientific reason, PT helmets shed krylon like its free. I have had to repaint this bastard like 5 times in 2 years. It looks like shit, I lose camouflage, and I just end up with big shiny spots on my dome. I determined I needed a cover, and if that cover included a counterweight pouch then all the better. A quick internet search located an OD green cover from some airsoft company that fit the bill, I think shipping cost more than the cover itself. A lot of cussing and screwing and cutting later, the cover went on. Well, it really wasn't all that hard, I just had to poke a few holes for the screws and get my methodology down, but I also despise putting helmet covers on anyways. I added some bungee that I cut off of some old ACU pants, in order to allow chem lights, strobes, or improvised camo, and made myself a counterweight out of some gun safe bolts and electrical tape, and I was done.
Here she is in her current setup. I'm pretty content. It retains all the comfort that I want, looks distinctive from the issued PT helmets that my comrades have, which keeps them from taking it on accident, (a real problem when everybody has the same helmet...), is much more useful than the stock configuration, and is extremely comfortable with NODs, (and MUCH MUCH quieter at night when busting through the pine forests, might I add!).
In summary, is it as good as it's high cost competitors? No, probably not. However, it works for me and I didn't have to drop $200+ on what is essentially a plastic bike helmet, plus it's unique and has features I use.
Hopefully this helps somebody. If anyone has questions fire away.
