In reply to TobyA:
Cheers for the replies folks, much appreciated.
The microlight is of course half the weight of my fleece jackets but I'm still not impressed by it. I get the fact that it is a midlayer but surely it should be warm to some degree on its own and I disagree with galpinos, it is definately not windproof at all and certainly not warmer than my old hooded Denali fleece, for me anyway.
As you said Toby, all that stitching means cold spots and I appreciate that if you stuck a shell over it it would make the whole set up windproof and you'd be warmer but doing that seems to negate the whole jacket to me. I can wear a base layer, cotton t shirt and a micro fleece and then a shell on top and that would work as well as the RAB and I'd be warmer.
I get that everyone wants everything to weigh a gnats bollocks these days but I'm not convinced it is fit for purpose but on the other hand, weighs nought and is easier to carry on the hills and more importantly to some folk, it looks good :0)
I reckon I'll just have to stick with the massive puffy jacket to keep me warm in the meantime then! Any more views, keep them coming and JWhittaker, I wouldn't want to test any hydrophobic down jacket in the wet. I get the idea but I'm not convinced it would work, better off with primaloft I reckon. Sorry to hear about your jacket, that would seriously pee me off!
Note to self, shouldn't have sold my DAS parka......
