Arc’teryx Nuclei Hoody Review

Bottom Line:

A versatile, packable, CoreLoft jacket. Perfect for belaying or as a midlayer. Face fabric (Arc’teryx Airetica) is water resistant but not waterproof so a hardshell is needed in a downpour, however, the Arc’teryx CoreLoft, unlike down, will insulate when wet as it retains its loft. I’d highly recommend it to others, another quality Arc’teryx product.

How I chose it:

Full disclosure, we are active members in a number of online communities, from nature conservancy and interest to outdoor equipment for enjoying the wild comfortably and safely. Arc’teryx is one of them. They wanted to say thanks for our continued support of their online communities by giving myself and Spring at Pebbleshoo a jacket.

We chose the Nuclei Hoody. We had already been considering it as we already have down jackets, but they aren’t practical to use if the weather is forecast to be wet as down loses its insulation when soaked. The Nuclei uses Arc’teryx’ own Coreloft which retains it’s insulating properties even when wet.

Observations since receiving and using it:

If you’ve watched our video review above you’ll already have heard most of my observations regarding this Hoody. I love the included stuff sack for packing the jacket which also has a loop attached to it so that it can be clipped to a harness with a carabiner when climbing. It insulates really well. It’s warm. It fits well.

I wear it everywhere. I have a coat rack at my apartment door and I don’t like clutter so I usually just have one or two jackets there that I put on when heading out. The Nuclei Hoody has replaced my old fleece Hoody as my go-to jacket.


  • Packable: Compresses down really well
  • Light: I don’t even notice it when I’m wearing it or have it clipped to my harness
  • Fitted: The trim design is awesome, it doesn’t bunch up or crease when I have it on under a hard shell and a heavy backpack
  • Vibrant: Personal choice, but I love Arc’teryx’ use of bright colors. For my photography the color of this jacket really stands out.
  • Simple: There really isn’t anything I’d take away from this jacket.

Cons and Areas to improve:

  • Stuff sack could be improved with a couple of compression straps on the side to pack the Hoody down even smaller. I don’t like carrying around air.
  • Zip or Velcro on the Stuff sack pocket: The pocket for the stuff sack does not seal, but the stuff sack can be removed. It would be nice to have the option of using that pocket to carry items like ID cards or keys when the stuff sack is not being carried. A piece of velcro at the top of it would allow it to be closed.

I grew up in County Dublin, Ireland and moved to British Columbia, Canada with my wife in 2010. I fell in love with being in the Backcountry and Mountains that are all around me here and try to spend all of my free time exploring those wild places. My main goals are to chase happiness, see as much of this planet and its cultures as possible and grow every day through knowledge and experiences.

    • We’ve always had matching jackets. Just different colors. Our hard shells have always been Alpha LT’s. Now our midlayers are the same.

      We’re “that couple” the kind that ends up wearing the same clothes as each other.
