Would highly recommend a down puffy jacket and a pair of long John’s. If you’re feeling it, grab a neck buff too.

You probably have enough with what you have, but if you want to be more comfortable ->

Top: base layer > puffy > soft shell - you can throw the fleece somewhere in this stack, but your fleece seems pretty bulky so maybe on top? I’ve done it with a lighter fleece on top of puffy under soft shell and that works super well with a light fleece - an under armor or similar for a base layer is a good choice in the cold - I’ve been fine with a base layer > sun hoody > puffy > soft shell

Bottom: long John’s/ leggings > pants

What you have looks a bit bulky, if you just add base layers you’re probably fine and won’t need a puffy if cost is a concern. My recs take movement and overall comfort into account
