#Note: Full Arc'teryx review at the bottom.
Kappa is now Arc'teryx's second warmest and the most weather resistant member (this parka gets the first place in this regard). This is the case since Arc'teryx discontinued Dually Belay Parka.
If you're looking for warmth in damp and cold areas, look no further. Arc'teryx Kappa is the right choice for you.
Mind you though, Kappa offers minimal breathability and is not packable at all. So keep these in mind as you read on.
My only complaint with this hoody is that it fits a little large. It feels somewhat bulky. Wish it came with a true regular fit instead.
Considering you only have a t-shirt under the Kappa, assuming little wind and casual use (no output), you'll most likely to wear it comfortably out in temperatures over 7 deg F (-14 deg C).
You can see a complete list of these results in the Arc'teryx spreadsheet I put together in here:
This sheet is generally considered very helpful by my readers. So you might want to see that.
Find below the lowest temperatures you can wear each jacket without feeling uncomfortably cold.
These are only approximate values assuming:
- you only have a shirt under and no shell over,
- during daily use (strolls, power walks etc at most - no high output activities),
- with light wind,
- and when it's dry out.

If you think you run warmer or colder than the average person, then shift these temperature ranges accordingly.
I've also put together an Arc'teryx spreadsheet recently. Might help you out:

This is the other important selling point of the Kappa. Owing to its synthetic insulation, it doesn't lose its insulating power when it gets wet.
This is the most important advantage the synthetic jackets have over down jackets.
Lastly, like most other Arc'teryx, Kappa also comes with a DWR coating on top.
DWR is a coating.
It's basically sprayed on to the surface of these jackets as a finish. It stands for Durable Water Repellent - which means that water will be repelled under wet conditions instead of soaking into the fabric.
DWR also decreases dry time.
It's a good thing these jackets are coated in DWR, but pay attention to the fact that DWR is a coating - meaning that it will wear off over time.
Which is why you might want to invest in a DWR spray such as this one for after treatment.
As you see, there's a strong correlation between FP x FW and temperature ratings, but not more than, say, 80%. I explained why this happens here in this post of mine.
Like I said, Kappa isn't packable at all. You must have a very good reason to pack it when traveling. I wouldn't recommend doing it at all.
Kappa isn't breathable. But I don't complain about this because breathability isn't something that Arc'teryx tried to achieve with this piece. After all, Kappa isn't designed for high output activities anyway.
Like I said, the Kappa fits a little large. No need to buy one size smaller to even things out though.
As you see, Arc'teryx does advertise the Kappa as regular fit. But I don't find this to be completely correct. I'd place its fit somewhere between relaxed and regular fit.
