Patagonia calls it a Down Shirt rather than a down jacket; actually, it's a pullover. And, Patagonia modestly calls it their "lightest-weight insulation" with no hype (thankfully) about it being the lightest down garment in the world. Technically it is. It's insulated with 800-fill power down and has a very lightweight 0.8 oz/yd² (27 g/m²) shell fabric, so obviously it grabs our attention.

With Patagonia's new Down Shirt we now have a total of four really lightweight down insulated jackets to choose from: the MontBell Ex-Light Down Jacket, MontBell Down Inner Jacket, Crux Halo Top, and Patagonia UL Down Shirt. Looks like we have four good contenders for an ultralight down jacket shootout.
