Torso-wise I think both models would work for me, but the arms were weird, the HL2, arms Velcro all the way to the end, ended up covering the end of my palms, about 5cm over my wrist bone, while Mach ones with plenty of Velcro to spare were just at my wrist.
I also tried the Elite size Medium as it was the only medium sized C/A they had, and the arms length was okay, but when I had my hands loose on sides of my body, I felt the them pulling down the whole unit on my shoulders.
Maybe I have T-Rex arms or just don’t fit well into Bauer
