People asked about all sorts of different jackets that are in different categories, but between the Patagonia Down Shirt and this, which is warmer? And how do they compare in general aside from the obvious weight difference?
Well, the weight difference is 0.2 oz in favor of the MontBell.
The MontBell has 1.8 oz of 900 fill down inside 7D fabric.
The Patagonia has 1.99 oz 800 fill down inside 10D fabric.
Despite a slightly higher amount of down in the Patagonia, there should be more loft and more warmth in the Montbell because of the larger baffles and higher fill power.
