not sure if that is normal with all covers, but it was a real pain to get on. no room to work with pulling the cover onto the helmet. pulled on a velcro strap that came off, so need to sew it back on, doesn't come with IR tab underneath the velcro covers. eventually got it on, but its not centered, and cannot move it around because its so tight. I have a L helmet, and cover said it was for a L helmet.
2 velcro straps came off when trying to put it on my MICH. I had to sew them back on IOT use it for training later that day. Weak stitching will fall apart with just a little bit of weight added
