So I tried it out last weekend and am very impressed. Straight away there are features on it that I hadn't realised I was missing like quick release at the sides for taking it on and off, the replaceable front panel for different loadouts, line retention on the shoulders for HPA/hydration.
Profile wise, it's actually smaller coverage on the torso that I was using but it feels tonnes lighter when wearing with my mag pouches and backpack for my HPA tank. It has a much better airflow system when wearing thanks to design and materials compared to my previous set up and is a lot more comfortable. I need to try it on a full day outdoor game but overall, I'm really pleased with it. The standard of manufacture is very high, and is something I can see myself using for years to come.
