Hi there!
I would highly recommend layers --- I brought long underwear, which goes easily under t-shirts, long sleeved tshirts, an LL Bean button up fleece cardigan, a thin fleece zip up, my Land's End fleece anorak, thin knit gloves and knit ski caps. I ended up wearing my anorak and the rest of the heavier stuff got farmed out to my crew who were not as well prepared.
I just wore regular cotton pants on the bottom, and was fine --- but then, I will wear capris and sandals as long as it's warmer than 55 degrees.
I am betting those jackets would work fine - especially if you had layers to go underneath... my only concern would be if they are heavy and bulky, then you have to lug them for the majority of the day. Anything that is fleece/microfleece will pack down tighter than cotton jersey AND if it happens to get wet, fleece/microfleece will dry much more quickly than anything with cotton.
