I really like the 240 and have worn it over a FL Minnerett Aerowool. If your moving that combo is good down to ~ 40-45 degrees. Add the Guide DCS over the Minerett and 240 and you could be good down to 20-25 if your moving. I'm looking at that exact combo, likely buy a Peleton 200, and adding a puffy for all my mid-late October elk hunting.

I still hunted the first AM of the TN gun season this year with a Outdoor Research Sequence next-to-skin and a Kuiu Ultra Merino 210 hoody. Temps were 40 or so with a pretty good breeze. It was plenty. I took a stand at lunch and again the last 2-3 hours before dark. I slipped the 240 on over both while on stand and was good.

I sent my Chinook back after wearing the 240............

I 'think' I have my mid layer narrowed down to the Patagonia R1 hoody and the Kuiu Peleton 200 hoody. I'll likely buy both - I do alot of hiking in the Smokys so it won't be overkill.

Adversity doesn't build character, it reveals it.
