I think Sitka Kelvin Active = Kuiu Kenai rather than the Peleton 240. I have both the Kenai and Peleton 240 - they are different animals.
I own both the Kelvin Active and the KUIU Kenai and they look quite different to me. The Kenai has more loft, and is warmer and stretchier. It has pit-zips and does not pack as small as the Kelvin Active. For me, it is more suitable for colder temperatures, probably too warm while hiking except in the coldest conditions, and more the sort of jacket I use when I stop to glass.
The Kelvin Active feels lighter and not so warm.
