Would this soft-shell serve double duty as an insulating layer in combination with a hard-shell?
Hi Simon - I like to layer a softshell under a hardshell from time to time. The thing to consider is that the Apex has a hood, which could be annoying if you are going to wear it under a hardshell, particularly if you also had on a backpack. If your primary need is insulation, you'll be much happier with an insulating layer, but if you're just wondering if this jacket could fit under a hardshell once in a while, it can and does add to the warmth factor of any hardshell.
The Apex does have a hood, but it is removable, so that is not your primary concern if you wanted to use this as an insulating layer. What should be your concern is that it is a little bulky because of the 100g of primaloft.
If you wanted to use this as an inulating layer, you could.... but surely there are more effective lower-profile ways to do that.
