Not the type of sweater you would wear to an ugly sweater party.

Pack the Patagonia Men’s Ultralight Down Shirt in your backpack. It’s so light you won’t even remember it’s there (until the sun goes down and the chill comes in). Quilted nylon treated with DWR protects the 800-fill down so you know it will maintain warmth and loft as part of your layering system or by itself.

perfect additional mid layer

I am 5'11' & 180 pound and wear L with Mountain Hardwear ,and M with Marmot. I always fall in between M and L with Patagonia. I chose M for this down sweater and leaving no space between this and a base layer, which i planed to do. Thin enough to be worn under a shell layer. A baseball size when packed.

great layer or out and about shirt

  • Gender: Male
  • Familiarity: I've put it through the wringer

This would be the perfect all around shirt if it included just a single small pocket. I don't like struggling with having to access a pocket under this layer or relying on pants pockets when wearing a harness. Other than that an amazing piece of gear for all those 'unknown weather' days.

sized to layer

  • Familiarity: I've put it through the wringer

Super warm, super light and easy to layer. If it's real chilli I throw this under my R3 and life is toasty.

Light and warm, packs well

  • Gender: Male
  • Familiarity: I've used it several times

This is a great shirt, easy to pack (compacts to the size of large apple or orange), warm and toasty, and so light it feels like you are not wearing anything. Love this shirt!

Great minimalist down layer, no fancy big zip, pockets bla bla bla. Just a super light simple layering piece. Gets thrown in my pack everytime I go snowboarding. If it's "alaskan" cold then I'll wear it under my shell.

Weighs as much as an empty beer can and stuffs down to about the size of one.

Great multi use down!

I love this down! it has been a great top layer on cold mornings and an under layer at camp or in cold conditions. It seems to keep me at the perfect temperature while hiking on a cold day, not too hot or cold. I love how light and compact it is as well.

Buy Nikwax or Granger's down wash. Put in a capful, and wash it in a front loading washing machine. Be very careful when moving it to the dryer, because wet down is heavy, and you could rip the fabric. Throw it in a dryer with some tennis balls to keep the down from clumping.

Great Layer

I us this as a layer for skiing. As other reviews will attest, this jacket is super light, and remarkably warm for its weight. My go to 1st layer (under a shell jacket) for skiing is an Arcteryx Atom LT jacket, which has a full zip + Powerstretch panels for ventilation, and so can be used over a wider range of temperatures. For myself, the optimal temperature range for wearing only the Patagonia Down Shirt (over a base layer) is around 15 - 25 degrees F. It works great in combination with the Arcteryx Atom when temperatures are lower and I'm not sweating a ton. Other things I love about this are: it's so small when compressed I have a hard time telling it's in my backpack; it's fairly windproof; it fits well and never catches on my jacket or other layers; the zipper goes fairly far down so one can get good (if not full) ventilation. Probably my favorite thing about it is that is so comfortable and light that I can't feel that it is on me. (The warmth tells me something must be there.)

Are you saying that this jacket keeps you warm at temperatures in the teens?

Ultra Light Down Shirt

Fits perfect and is toasty even with just a T-Shirt on. Asked the backcountry rep about size and they were spot on.

get it and forget it

Fit is Slim. So fits like a t-shirt. I put it on and forget that i am wearing it. Stops wind and extremely light, Love the minimalist design at waist and wrists. No pockets, comes with small stuff sack about the size of an Apple. The squares add warmth and rigidity. Love it.

pat. down shirt

well i have had the shirt for 2 weeks now and have worn it everyday. our home is about 60 degrees at
this time and it feels like it is 72. this shirt tempered
my on and off chills recently when i had a touch of the flu. i normally do not rate a piece in my arsenal so quickly, however, this 6 ounce shirt is awesome!
it is especially awesome when it is 30% off retail.


p.s. i would have given it 6 stars if it had been made here in the u.s.

Coolest (uh Warmest) jacket from Patagonia

I am a huge fan of the "Bird", and if you looked in my closet you would think that it was an Arcteryx store,but Patagonia's down sweaters, nano puff jackets, special addition 900 fill jackets are a dream come true.When they came out with the down shirt, I just knew that I would have to have one. Buy one and I promise that you won't be disappointed.

Montbell UL Down Inner vs Patagonia Down Shirt

Montbell UL Down Inner vs Patagonia Down Shirt

No Comparison. Montbell WAY warmer and cheaper.

Responded on

That's not comparing apple's to apple's to be fair. To be closer you would maybe compare MB ex light but not the UL.

Responded on

No comparison is right- you just chose the wrong winner. But to be fair, the purposes of the two garments are different. The Patagonia is not a jacket, hence its referenced to as a "shirt." The Patagonia is designed much more as a specialized piece. It may not be quite as warm as the Montbell (I don't know if THAT'S even true) , but it is certainly lighter. And if you're climbing a several pitch track, EVERY gram counts. where as the Montbell has a greater range of temperature in which it is effective.

Compare to Montell UL Down Inner

I bought this to compare to the Montbell UL Down Inner. Patagonia does not post their fill weights so I asked the Patagonia rep. She said there is 2 oz of Down fill in this shirt. Now that I have the Patagonia and the Montbell Inner I can say there is NO comparison between the two! I don't know if the Patagonia rep lied or the tiny box stitching hampers the ability of the down to fluff up. The Montbell box stitching is twice as big as the Patagonia and this allows it to fluff up about 4 times the loft as the Patagonia (hopefully you can see this in the photo).
Things I liked: Simple design; less zippers to snag on the very fragile material.
Things I did not like: Way too THIN to provide much warmth. Price, even on sale it was much more than several Montbell options.
Montbell UL Down Inner
Things I liked: MUCH more down; fluffs up nicely; feels warmer. Excellent price and warranty.
Things I don't like: I don't like the pockets. The down is in the exterior portion of the jacket and the pocket is basically a piece of added material on the inside. This allows the pocket to pull open creating a small slit where there is no down. I intend to stitch the pocket closed so the pocket does not gap and cause a cold spot.

i was checking up on montbell reviews, and a bunch of them said feathers were leaking like crazy. im thinking i would rather have a more durable one with a little less insulation, than have a product which requires "special care," as they put it.

Responded on

also, i would like to suggest another of my considerations...the patagonia ultralight down jacket. maybe this one will provide more insulation, with the added bonus of being lightweight and ultra-compact for portability.

This is the same lightweight, windproof, nylon ripstop exterior shell fabric used in the Special Edition Down Sweater. Half the weight and twice as strong as that used in the Standard Down sweater.
