Before you pass judgement you need to at least try one on or see it in the flesh as it is utterly different to any other motorcycle riding kit.
Tried the Klim Jacket at The KTM Centre... Interesting design - but not for me...
Whereas in other jackets there always seems to be a size to fit me (am I'm normally a large) I couldn't find a size in the Klim Adventure range that was at all comfortable... No matter how we adjusted the harness.
The large was obviously the size I needed but there was an abundance of loose material which "rucked up" on each side across from the zipper, over the collar bone area to the shoulder... When sat on a bike this "gathered / bunched up" to a point that it affected comfort of the neck area and pressed against the base of my Schuberth helmet...
With Jack's help (from the KTM Centre) we adjusted all the straps on the harness several times to try and "tailor" the jacket as we should have done - but to no avail.
Tried a medium as well but that was obviously too small.
Interestingly, two other people tried the extra large size Adventure jacket on while I was there and felt the same...
The guys at the KTM Centre offered to call Chris at Adventure Spec to see whether any adjustments / alterations could be made... As I didn't hear back I decided I did not want to spend £1,000 on a jacket that would be a bit of a compromise comfort wise or that had to be altered (if that was possible - but I'm not sure if this is feasible as I didn't get a call back as I say) and went to audition the new BMW suit...
The Rally Pro 3 however fitted perfectly straight off the shelf and I got jacket, trousers and gloves for less than the cost of the Klim jacket... I should have gone their first maybe ??
I suppose we are all different shapes and sizes, but I was surprised that 3 people, all excited by the discussion about the jacket, found that it was nowhere near as comfortable as we had been led to believe...
For me, the Rally Pro 3 has turned out to be an excellent buy. Better comfort and a lower price...
And, to answer the OP's point, well worth the money... In rain, cold weather and, this weekend's, heat it has been very comfortable...
