Patagonia DAS vs Arcteryx Atom SV

Which is warmer?

Best Answer Responded on

The DAS is approximately 60% warmer. DAS uses Primaloft One which is 5% warmer than Coreloft per gram. At 170g in the torso and 133g in the hood and arms, it has an average of 159g of insulation distribution. The Atom SV has 100g of Coreloft, which equates to approximately 95g of PL1, since Coreloft isn't as warm per g. Final math comes out to approximately 60% warmth difference.

That said, they're both great pieces used for different applications, and the above calculations don't factor in fit, draftiness, etc.

Good to know. I am 6'2, 190. What would be a good fit. I hear this jacket runs big! I want it to fit over my action suit (base, mid, hardsehll) but not feel like a marshmellow.

Just saw your response Josh. While I have wanted to love the DAS, the fit hasn't worked for me. If you're 6'2" 190, my guess is that a Medium would be a good fit. It may have slightly short sleeves, however. I'm 5'10" 200 and the Medium is still pretty big for me, with accurately lengthed sleeves but a very large torso. I swim in the jacket, a bit too much in my opinion, making it drafty and meaning I carry too much extra insulation.

FYI, they are updating the DAS for 2013 which should provide a better fit for you. I'd advise waiting until then to see what they produce. However, it will only come in orange and black colors until Summer 2013.

The DAS Parka does run big BUT it is a parka. Parkas are designed to run big so that it fits over your base layer, mid/fleece layer, down layer, and even shell layer.

Try pairing your Atom SV with a Patagonia nano pullover. More versatility and very similar insulation. If you want to be even cooler, pair an Atom LT hoody with an Atom SV. A few ice and alpine climbers rave about this system. R1 hoody base layer, Atom LT hoody for active use, and Atom SV over everything at the belay. Ultralight hardshell in pack of course.

Of course I have nothing bad to say about the DAS. We'll see how the new BD belay parka compares
