Rated 5 out of 5 by from This jacket is truly amazing. I've bought this jacket mostly for moutain hiking/climbing at winter. It fits me really well. Coreloft does its job amazing while I feel very comfortable and warm with lightweight baselayer underneath it at 0 degrees. I tried it also at windy conditions and I could say that windstopper worked as great as It's designed. I would recommend this jacket everyone who move quickly and wants something warmth enough at these cold winter days.

Rated 5 out of 5 by from Unbelievable belay jacket - ultralight version of Kappa Hoody In a nutshell, this is an ultralight version of the Kappa Hoody, which is an amazing belay jacket. The Nuclei AR uses 100g Coreloft vs 140g in the Kappa. The Nuclei is 15.9oz vs 26oz, and the stuff size is about half that of the Kappa. The Kappa should be a little warmer, but it doesn't feel like much. The 20 denier Windstopper fabric on the Nuclei AR is much lighter and more packable than the 70 and 80 denier fabrics used in the Kappa. It's also much more supple, and because it's so much lighter, I think you get more loft out of the insulation, potentially closing the warmth gap between the two. The Kappa will be much more durable, but I think the Nuclei AR will be durable enough for years. The Windstopper outer shell is fully seam taped, so it should be near waterproof in all but the worst downpour, and it feels reasonably durable. I love the big drop-in pocket inside for gloves or whatever. The Nuclei AR comes with a stuff sack that comes attached to the inside of the jacket (but can be removed). The stuff sack has a loop for clipping to a harness. It will be amazing to have this little bundle of awesomeness clipped to my harness this winter. The hood is standard Arcteryx fare, meaning it fits over a helmet, and has good adjustment. I got the purple Azul color. It's a bluish purple to me, despite azul meaning blue in Spanish. It's a good looking color, to me. The fit is belay jacket appropriate. It will fit over layers well. As is usual for me, I was torn between medium and large, and couldn't try one on before buying. I'm 6'2" 180lbs, with a 6'7" wingspan. I usually need a medium body but large sleeves. I went with large, and am happy. The hem and shoulders fit well. The chest/stomach is large, but will suit its use as a belay parka. I will use this both on cool days over a base layer as well as frigid days ice climbing over a base/mid/shell combo. So having room is nice. To me, it's slightly larger than the large Atom LT I have. It has good butt coverage. Literally the only bad thing I can think of is that it lacks the double zipper and bottom snap of the Kappa (allowing your belay device to come out of the zipper), which is understandable given its mission as an ultralight alternative. I will make due with it, but a double zipper and snap would have made this jacket the best insulated jacket on Earth. Without those, it's top three. The Nuclei AR hits all the sweet spots. It's ultralight (for the warmth), it's totally windproof, it's seam taped for added water resistance, it's very packable, it has a stuff sack that attaches to your harness, and it will insulate even if wet. Well done, Arcteryx!
