I love a windproof jacket. I mix and match between a soft shell or a windproof shell
I have a few now but only one has a rear pocket. I have a gore contest one, has a rear zipper pocket that it packs into. Use this for MTB
I also have a Rapha one that I use on the road. Think its the classic wind jacket. Use this most days for commuting. has a couple of reflective stripes down each arm that offer a bit of stretch. Very comfy and really nicely fitted, packs down smaller than the Gore one but no rear pockets. Has a tiny one on the front that nothing fits in! Also has some nice touches like a bit of mesh around the armpit
Both have really long arms for a good roadie pose, even for me at 6’3
I find a quality windproof jacket (I love my montane litespeed for hillwalking) to be an excellent bit of kit. Cheap ones really don’t breathe that well, good ones are ace – for cut, function and quality of the fabric
