I came up on an opportunity to purchase an insulated pants/bib and a hardshell/bib for a pretty good deal. My only concern is, would this be annoying as hell when climbing, or do people do it with not much problem?

Thoughts/recommendations?

I should have clarified, I should have asked would it be annoying as hell to wear them both at the same time?

I've been doing it for years. I have a goretex bib with a softshell bib underneath.

My set works great but you wouldn't want it to be too bulky. both sets have side zippers so cooling is not a problem. I use it for skiing, ice climbing, and any alpine stuff.

When it is warm out i take off the goretex bib and use just the softshell.
