I am currently looking for the best Down Sleeping Bag I can find without breaking 200$

It would be nice to spent around 150$ or less if possible but I am willing to spend up to 200$

I will be using this mainly for summer for different segments of the JMT.  Not sure on the exact spot but most like a 5-7day trip.

These are the current bags that I am looking at buying.
