Arc’teryx Atom LT or Sitka Kelvin Active?

[Flyrod]

So I have an Atom already..... is going to a Kelvin Active redundant? Or even a step backwards?

I seem to have SubAlpine-itis....and I’m slowly replacing everything over.
lol

Thanks for looking.

Seems somewhat redundant. The kelvin active seemed to be a lighter layer when I saw them in store, the atom should be warmer.

I used the hell out of the active this season. warm for weight, dead quite so i never worried about it as an outlayer on a stalk. it packs to nothing. only thing it wont do is block wind. If its windy it goes under a shell
