I suppose I could post a little feedback on the IOTV.
I've been waiting to see how it works out for some period of time before posting anything, I've had the vest for about 2 months now and was using the IBA with side plates for the prior 8 months.
I spend about 40% of my time mounted (1151) and 60% dismounted, various terrain.
I carry 2 5.56 HSGI 3 mag panels, 4-9mm , strobe, smoke, 2 6x6 GP pouches loaded with trauma goodies, M9, and some hasty balsa wood splints for pressure dressings in the back. I also grab a camelback full of blowout packs, airway, etc..
Unlike the IBA, surprisingly, all this stuff fits, and fits well on the IOTV. With the cumberbund style closure/ over the head donning, I am able to mount everything forward for easy access unlike the IBA. I had to use my chest rig to get the stuff where I could use it. Camel back fits great, no funny buldging, straps fit well over the shoulders.
Three words: Comfortable as hell.
No matter how well I adjusted the IBA I either got it tight enough and it was a bitch to close or loose enough to close but not tight enough to ride on my torso. The IOTC distributes well and feels like it's part of me.
The internal cumberbund works well suspending some of the weight to the torso, although it creates a nice hot spot when I wear the combat shirt, I forget all about it after about 10 minutes.
The medical access cover on the left shoulder holds a SOF-T or 2 CATS perfectly.
In the truck the vest remains where it's supposed to. Only bitch I have is the poor velcro job for the collar. The tiny squares are there to ease the release when the QR is pulled but the collar slides in and out laterally. It always catches on my VIC headset and it irks me a bit, a quick adjustment and all is fine.
Despite being designed to have more axial protection I have noticed that there is still an ability for fresh air to get in, which is a nice bonus.
Got into a nice little "length of our man parts" contest a day or so ago and found my self at a dead sprint down a few hundred meters of rough terrain. The vest stayed put, didn't bounce and I had no problems reaching up on ledges and climbing walls, houses, etc. Huge improvement over the IBA with the side sapi and daps.
Only gripe is there isn't a decent place to connect a 'biner or wolf hook on the shoulder. The plus side is I can place it on the uppermost row of webbing and it keeps the rifle from slipping past the lower profile shoulders. The QR channels also make excelent storage for zip cuffs without interfering.
QR has not had any issues catching on anything. I pull mine once a week to insure it works and that nothing is kinked up or holding the vest together.
All that said, it's really up to the end user to ensure the vest is adjusted right and fits well but I know for sure that you can toss a lot of crap on this vest and it is much easier to wear and still be able to toss it all on in one swoop, and it's more comfortable to boot. Inshalla I won't have a report on the vest's protective qualities.
That's all I have.....9/10. I'll give it a 10 when we get it in multi-cam.
