With such an advantageous warmth-to-weight ratio, there is no excuse to leave home without it.

  • 10D nylon ripstop shell is exceptionally lightweight, durable, and is has a Deluge DWR finish for water-resistance
  • 800-fill European goose down provides an unrivaled warmth to weight ratio
  • Quilt pattern controls the movement of the down for improved warmth
  • Slim fit allows you to wear the shirt on its own or layer it beneath outerwear
  • Elastic cuffs and a drawcord hem keep weather out and warmth in
  • Self-fabric stuff sack allows for compact packing

Here's what others have to say...


Great piece of kit, but...

  • Familiarity:I've used it several times
  • Fit:True to size

It could be improved by sewing the stuff sack inside the zip to make a useable napoleon pocket. I would encourage Patagonia to also make the same without sleeves (pullover vest)

Whats the fill weight? Trying to decide...

Whats the fill weight? Trying to decide between this and the montbell EX-light.

56.5 grams to montbell 's 51 grams.

I had the Montbell and it was really a great piece at 5.6oz. I appreciated the extra lifting it allowed over Pata's tight baffles.


Oh I LOVE this thing

  • Familiarity:I've used it several times
  • Fit:True to size

I have two Patagonia down sweaters, one full zip the other an anorak style. Both are wonderful. I was kinda skeptical that I could use (or really needed) another down pullover.

This thing is awesome. It's so light you hardly notice it's on your body. I wear it skiing, and it seems to keep its loft when its a touch wet. The collar zips up really well to help regulate body temp too.

No pockets or hoods or anything like that. It's basically a high tech version of your basic insulation layer, but when the wind was howling @ 20 mph and I'm on the lift buckled down, a wool layer, this shirt and a Patagonia shell keeps me comfy and warm.

Does the black one look all iridescent...

Does the black one look all iridescent sort of like plastic or a garbage bag as the photo suggests?

I would not go so far as to call it a garbage bag color but it is closer to that than a matte finish. So there will be some sheen but I don't find it to be garish.

Best Answer

Iridescent is a good way to describe it, although it will tone down with use and washings. The Patagonia down shirts/sweaters are great pieces of gear, but it will always be about the shiniest jacket you own. I would call the photo accurate. You might initially be a little shocked when you first receive it and see it in real life, but give it a chance and you'll be impressed.
