Well, I used my brand new Argo jacket today.
I'm not experiencing any problems with the "zip" closure thingy as yet, but I confess to thinking it to be just a gimmick, and nowhere near as reliable, and as easy to use as a zip.
I can't pull the toggle right to the top, for 1, fearing that the the thing would tear itself apart, and 2, because it makes things very tight round my neck.
It also makes the jacket feel too rigid.
Another criticism is the neck flap hitting me in the eye when putting the coat on.
I'm aware that the flap can be folded on itself, but it is still easy to forget, and stab an eye.
If I'm honest, I wouldn't buy another jacket without a conventional zip and flap.
I will persevere with the jacket, but I'm just glad I didn't pay UK prices...
