Two days ago i received my Klim Kodiak riding suite, i ordered it with the intention of using it when i go for long rides in winter, it is also better in the rain than leather.
It came with a thin down puffer jacket (800fill). Just out of interrest i decided to compared the down jacket to the primaloft IH and was blown away by how much warmer the Klim down jacket was.
Even when worn underneath my leather jacket i can sustain much higher speeds without ever feeling cold, it is far superior to the primaloft.
The only two advantages the IH has over the Kilm are the fact that primaloft retains warmth even when wet/damp, and the fact that the nylon outer shell is much stronget and less likely to be damaged if handled roughly.
Comfort wise i prefer the pattern of the Klim, it doesn't have the tight shoulders of the IH and it is much warmer. As long as the weather is cold enough to prevent overheating and sweating (sweating in down sucks as once it becomes damp it looses all warmth)
Basically i think that from now on i am just going to keep the IH as a "keep it in the paniers at all times just in case i get cold during the day", it is tought enough that i won't worry about it getting damaged in there.
If it is really cold and i am leaving home with layers on knowing the weather will be cold i will wear the Klim.
