Just want to say that I am not military, so in no way, shape or form am I putting this product through the intensity levels they may see in that field. With that being said, I do use this in my kit for firearm training at the range, as well as airsoft skirmish and scenarios. The IcePlate Curve has probably seen around 50 hours of use since May 2021. There is only one problem that I have with the IcePlate, and that is with the IceCap/IcePlate Port.
I'm not sure if this is how it is with everyone's, butt I find that if you tighten the IceCap to, what feels like, completely snug, it will "strip" and slip off the grooves, resulting in profuse leaking. However, if you only give it "60%" pressure when tightening, it seems to hold all liquid with no leaks. (At least from my experience.) I may add some PTFE tape to see if I can use that to get a full tighten down without leaking, but besides that - it is an amazing product and well worth the money.
I only use the Sleeve Pro for those extremely hot, humid Florida days, where I will run it on the inside of my plate carrier, frozen to help cool down. Works amazing and is worth it right there alone. Almost want to buy a second one for the front as well, haha. For non-frozen use, I will run the IcePlate in a third-party storage on the rear of the carrier, but the same concept applies. Keeps you cool on those hot days, keeps you hydrated...always. -1 star for the issue with the leak, but again - that could just be my unit or a mistake I had made in the past.
Do recommend!
