I got the BPL hoody in size M. I'm 6 feet & about 165 pounds.
I like the new hoody a lot but found it a little floppy even in size M to be an ideal Next to Skin layer. Picking a smaller size would make the arm and torso lengths too short so in the end it was a compromise. If you are larger across the chest or stocky, might not be an issue
When perspiring heavily, my icebreaker in size L does a better job with efficient moisture transportation and drying on account of the more athletic fit (of course a synthetic shirt would do even better but synthetics stink). Not a big deal, I ended up using the hoody over a icebreaker 150 short sleeve and the combo works great.
Compared to the patagonia R1 hoody, the BPL hoody is about 2 ounces lighter for the same fit but is also less warm. On a recent Utah trip I tried both back to back in temps averaging 35 F during hikes and found them very comparable. When the desert sun came out in full force the black patagonia got too warm whereas the BPL hoody was still comfortable. But when the evening temps dropped the extra warmth of the Patagonia was appreciated.
In the end they are both great.. chose accordingly based on whether you want wool or fleece. If I had to chose one, I'd take the BPL hoody as it is more versatile as part of a layering system.
P.S. Wearing the BPL & R1 hoody at the same time didn't work for me, it felt tight & awkward and one already has too many hoods to contend with when also adding an insulation layer during camp time
