I am looking at the arcteryx atom ar Patagonia nano air First light uncompahgre Any one tryed any of them? I am worried about warmth with the synthetics. Hope the snows flying in your zones. Adam November 24, 2016 at 11:41 pm #796569 Cascade Cruiser 15 Posts I was recently looking for a light to mid weight synthetic hoody and picked up a Rab Xenon X jacket. It was either that or the Patagonia Nano Air. A few friends have the Nano and they love it. From what I’ve read the Rab is more weatherproof but less breathable. Both are super light! I decided I’d rather have a little more protection from the wind and wet as im in SE alaska. I have not had it out riding yet but im pleased with the quality and warmth so far considering its so light. Definitely a slim fit December 19, 2016 at 1:17 pm #797356 Yoda 264 Posts Here are some facts to consider as far as which garment will be the warmest. It’s all about the amount of insulation! Arc’teryx’s Atom AR will be the warmest with 120g/80g insulation. Arc’teryx’s Proton AR (equivalent to the Patagonia Nano Air) will be less warm with 90g/65g insulation. Patagonia’s Nano Air or Nano Puff will be even less warm with only 60g insulation. First Light does not indicate the amount of insulation in their garment, so who knows how warm it is. I would also avoid ANY brand that states a temp range for their products as this can not be quantified when it comes to garments. If you’re worried about warmth with a synthetic, you should be solely focused on the amount of insulation that’s inside the garment. Unfortunately most brands fail to indicate this information.

Unfortunately most brands fail to indicate this information. I wanted to chime back in a say that my statement above is coming from the perspective of the heat that is being created by the insulation is being protected and preserved by an outer shell fabric or covering. Arc’teryx and Patagonia for example both make synthetic jackets that preserve the heat that the insulation is generating with wind resistant or windproof face fabrics. Other synthetic jackets (also made by both of these companies) are designed to be more “air permeable” and utilize reduced wind resistant face fabrics, thus the heat generated from the insulation can be lost faster if not protected by an outer shell. The Arc’teryx Atom AR is more of an outer jacket that can be also used as a mid layer in colder conditions. The Patagonia Nano Air on the other hand is more of an mid layer since it incorporates an “air permeable” face fabric and insulation (hence the “Air” name). It still can be used as an outer jacket in milder conditions, but it will not be as wind resistant as the Atom jacket.

The last several years I have been running a base layer, marmot driclime which has some moisture resistance and dries crazy fast, then a having a synthetic puffy jacket over it all for transitions and descents and sunset exits after a long day. I have been leaving the shell jacket at home unless I’m expecting a front to come in or real wetness. Viewing 6 posts - 1 through 6 (of 6 total) You must be logged in to reply to this topic.
