I have the summit zero jacket..I thought the only difference of the summit and the zero is the hood...

The jacket doesn't have much warm material in the inside, so if you are in colder env. you probably need a inner fleece jacket like you said.

I live in Vancouver where the cold doesn't get too bad, even the coldest days last year I was able to wear the jacket with only a t-shirt inside. Plus we get rain pouring all winter so I got the version with the hood. Although I find it unless in everyday/airsoft events, where I got use to the rain already in everyday life here and it just helps fog to get into my goggles/mask in airsoft...

And because I live in Vancouver, playing airsoft with this jacket is just too hot even in the winter.So much so that it became just a normal everyday softshell, but in Toronto it might be a whole different story since it's a lot colder.
