I am considering the fission sv or the kappa sv for use around town. Which would be the warmest as i am trying to avoid layering.

I think you are going to find that these are very similar, with the Kappa SV being slightly warmer. The Fission SV uses a mix of 200g/m2 and 133g/m2 Primaloft while according to the website the Kappa SV only uses 200g/m2. I'd guess that the lighter insulation used for the Fission SV is in the sleeves, which actually seems like a pretty good compromise to me. The bigger difference between these two jackets is the shell fabric: the Fission SV uses the Gore-Tex Pro Shell while the Kappa SV uses Windstopper. Both are windproof, but only the Fission is waterproof. I actually just realized that the backcountry.com specs don't match up with Arcteryx's website. According to the Arcteryx website, the weight of this jacket is 2 pounds, 4.1 oz (1000g), not the 21.6 oz/614 grams listed here. Also, the insulation is Primaloft, not ThermaTek.
