Arc'teryx  Nuclei Insulated Hoody - Men's

I’ve had the previous nuclei FL hoodie jacket for a year now. It’s my favorite light weight jacket so far. It keeps up to all its requirements. The insulation does well, sometimes too well, so the jacket is mainly for colder temperatures for that reason.

Very light but keeps you warm and windproof. I find it perfect to wear as a mid layer also under my Beta AR shell jacket for winter weather. It also looks very stylish and the colour navy is gorgeous (black sapphire).

The jacket is lightweight and feels pretty comfortable all around. It’s a bit on the slim size so size up for layering. While I agree it is warm, it’s also not breathable. You will soak in sweat if you do any high output activity. This is basically a high end, insulated windbreaker.

Purchased this jacket three weeks ago. I had bought this jacket simply because of the low weight to high warmth and especially it is a synthetic. I was in the Scottish Highlands attending and the Cateran Yomp so need my pack to be as light as possible. I have the cerium hoody which is amazing, but for wet cold conditions the Nuclei is superior ! This jacket delivered in spades!

Highly packable, lightweight, incredibly warm for it's size, performs well during activity when it's cold. This has replaced my light down puffy in most situations!

One of my most favorite jaces of all time. Dont let its simple looks fool you, this is an amazingly comfortable and useful jacket. Whether wearing it on its own, or layering it under a shell. Great mobility built into the pattern engineering and fit, warm when you need it and never getting too hot, beathability is the key. I prefer this to my down jackets for comfort and mobility. not just great on the mountain also great on the sea. Yes it is super light, which is part of its beauty comfort and mobility. Had to buy my son his own so I could get mine back.

II bought this a couple of weeks ago and have had in the backcountry of Montana. Very packable, very warm, it is windproof, and fits true to size and now allows for layering underneath. 5 star all the way. Do not buy this if you need breathability......this is very windproof and for static or low activity. It will be perfect for on piste skiing but not actively hiking in the backcountry. It will be excellent as a packable puffy for the backcountry when added layers are needed.....waiting for the slow pokes. 2 things: 1) Absolutely needs an exterior chest pocket 2) More colors starting with UN blue BTW - you hardly know this hoody is on. Very comfortable, lite, and it is solid against our high winds in the Big Sky state.

I love this jacket. It is one of the warmest jackets I own and it compresses down to the size of a Nalgene bottle. If the weather is iffy/cold whatsoever, I do not hesitate to throw it in a pack or clip it to my harness -- it is just that lightweight. This is not a jacket you will wear while ascending/running/or doing high output activities, but rather it is more of a belay jacket, or a basecamp jacket. It is fairly durable -- I have had mine for 5 years, I climb with it around 30 times a year, and I only have one tear in the body of the jacket.

I'm so glad this piece was brought back from the dead, and better than ever. For me, it provides the perfect combo of warmth, packability, and storm protection. My only minor issue is the face fabric durability - I wish it were 10% tougher to prevent nicks. I just used this for 14 days straight in the Alaska Range, wearing it as my ski and belay piece. I then took it as my only outer layer for a quick ascent on Tahoma, where I used it to wait out a summit storm. It's not designed for movement, but I booted in it for 1000m in very cold temps. The huge win for this piece is the warmth to weight. It packs smaller and is much warmer than the Atom LT, and is a more versatile piece than the Cerium due to the synthetic. I'll be using it on all manner of trips up high this summer and fall!

I love my 2013 Nuclei and this new version corrected all 3 issues I had with that original. By adding an adjustable hood, zippers that don’t catch easily, and most importantly adding interior dump pockets, they created the perfect winter jacket for me. (Arc’teryx, why oh why don’t you add dump pockets to more of your pieces?!) It’s too warm for me to wear it if it’s going to be over 35F-40F but it’s killer for anything colder. I resort snowboarded in it in temps between-5F and 15F and was perfect with only a Delta LT 1/4 zip underneath. That’s it. 2 layers. If I’m only moderately active in it with breathable underlayers I don’t get swampy in it. I don’t climb but use it for most anything else. Also the fit and articulation are fantastic. If I’m working hard it still comes with as it packs down to nothing and goes over everything. It’s great.
