Recommendation on insulation jacket

Hello!

I am going to patagonia next mid-february for a month, then continuing my woldtrip. I am looking for a puff jacket, the rest of the setup is already there. I will mainly use it during hikes/ evening at camps.

My current setup:

200g/m² Icebreaker baselayer
260g/m² Icebreaker Quantum Zoneknit hoody
Patagonia Triolet hardshell

Now my question is, what SYNTHETIC insulation would you recommend? temperatures can get close to 0°C.
I had a look on the patagonia micropuff Hoody but i am not sure if this will be warm enough. Any recommendations are highly appreciated! Budget is 500 USD max.
