Fleece does get thinner and therefore loses warmth after a few years of use, some more than others. So you may want to consider getting a new one.
my layers are wool singlet, shirt, wool jumper (angora or possum down) and light rain/wind jacket (gloves and hat) if expecting down to about 5c, lower I change to singlet, wool mid layer and a light down jacket as well as a beefier "rain jacket"
A couple of items that I find very useful are a Buff (use that on my neck or wrist sometime as a head cover at night) and plastic bread bags.
At camp when I have wet boots I wash my feet, put sock liners on (my night Coolmax socks) then the plastic bag, over the bag I put my wet socks on and my boots.
.So I have dry feet and start "drying" my socks that way.
Forgot...
In the alps I always have rain pants and often gaiters too.
Oh dear
What I think I take and what I do is not always the same...
I am sorting out the gear for the next trip , so I could have put a better comment in the first place if I had taken a good look at what I have prepared so far..
On top of the above I almost always have long wool underpants (camp/night layer) and often have waterproof mittens (light shell)
