Versatile, High-Quality, Understated

Got this at a Black Diamond store when they opened one in Denver area. I find this jacket (in particular, this all black style unlike the new models of the same jacket) to be a really nice understated piece that could probably be worn skiing (I dont ski) but also as a classy looking coat for around town in the late fall, early winter days. Marketed as a shell, this jacket offers more with insulation in key spots. The material on the outside feels relatively soft, not crinkly as youd find in any other shell. Slipping it on, the liner and light insulation make this thing feel slinky, comfortable and effortless to wear. I wish the pit zips were shielded from the wearer. With a base or mid layer, Ive felt comfortably warm. The weather protection from the exterior material they used I found impressive. Not marketed with Goretex but whatever proprietary stuff they made kept me dry amid constant drizzle/occasional light rain when out and about. Other notes: I enjoy the lined hand pockets to keep hands warm and the larger external chest pocket for larger phones, etc. There is also an interior mesh stow pocket for hat/scarve/gloves and another zip pocket for other essentials. The hood functions well with just one point of adjustment. FIT - I find the jacket mostly true to size. Based on the sizing chart, I am right on the edge of M and L. If in between sizes, choosing the smaller size can be doable if youre satisfied with a more tailored/trim look but I wouldnt say it runs large. Normally chest constriction can be the limiting factor for some when in between sizes but that wasnt a noticeable concern for me where it has in other coats - likely not as much of a factor with less insulation. This coat compares well with something like a modern Arc'teryx Radsten Parka - similar understated styling, comparable to perhaps slightly less warmth, weather protection and versatility. The Radsten is too small in the Medium and too boxy in the Large for me so Im returning those and enjoying this. This is a great choice for temps near but now below freezing provided a sufficiently warm underlayer is worn.

Fits Well - Nice Material

I've used it once or twice and have initial impressions
True to size
Size Bought
5` 9"
165 lbs

For reference, I'm 5'9 and ~165 lbs., and the medium fits great (it's slightly long in the torso but fits perfectly once the draw-chord hem is synched up). I haven't had a chance to wear it outdoors yet, but my initial expectations have been exceeded. The material is soft to the touch/stretchy-ish, yet feels very rugged. Once opened up, the jacket has a snow goggle mesh pouch inside the left side, and an inside zipper also on the left side that looks great to hold a phone etc. The chest pocket is very roomy and deep as well. I put on my Patagonia down sweater underneath it to see how well it layers, and it still feels roomy and stretchy (I bought this primarily as a ski jacket/shell). The Patagonia down sweater would probably be the heaviest mid-layer I would use underneath it, so anything smaller/lighter underneath this would work perfectly. Overall, I'm very pleased with the material and am looking forward to using it in the snow.

Simply false advertising

I returned this product before using it
Runs large

It's just a piece of thin cloth, it could be worn in June or July, but not in winter unless you put it over sheepskin coat. What a joke. Simply false advertising. Most importantly it's in a wrong category, it's not a jacket it's a shell, but it's tight so it will be difficult to put anything under the shell, so it's useless.

Thanks, really helpful review

I'm confused by your comment. You say it runs large but yet you can't fit anything underneath?

Its a ski-SHELL jacket that has light insulation. I find this a nice looking understated piece to wear for skiing or for around town. With a mid/base-layer, I dont think you need much more unless you approach freezing temps. I dont think they falsely advertised.


Does this jacket have a hook or loop to attach to pants? Similar systems can be found on Patagonia and TNF ski jackets and pants.
