Anoraks look neat. I've had a few. Mine were shells - outer garments that you wear over other outer garments that provide the insulation. Or you just wear the anorak alone in the rain or wind sometimes.
Over time I found that I did not like the inability to adjust ventilation. When it's on, it's on. No adjusting anything unless you take it off. This would be fine if you were in a persistently cold area where you wouldn't dare think of taking your coat off. But it didn't work well for me in more temperate climates where coats have a middle setting between on and off - namely "unzipped". I also found my non-stretchy anoraks to be no fun to put on or take off. Kind of a pain actually - like they were fighting the process tooth and nail. The stretchy ones were fine. I am guessing that the insulating anoraks would be much better in this regard - they have some body and bulk and weight to them that would help keep them falling straight, thus easier to put on and take off.
