I use an adventure light all year except in summer, I have aspira for hillwalking.
They are a bit warmer than just a shell, I just wear less under it as Ai find they breath better than gortex for a given insulation level.
Big benefits for me are...just reproof every now and en with nikwax and its back to as good as new...effectively never wears out, gortex or any other does with washing and use.
Repairs can be undertaken on any garment for a fixed price, colour matched...we have people with 20yr old jackets in the climbing club, rip an arm...no problem, send it off, £35 later...jacket like new.
In really really wet weather, they still keep you dry, again gortex can get overwhelmed.
If you do just snag it, sew it up and as long as its proofed, it stays waterproof due the way it works, unlike a membrane should the membrane get ripped.
Essentially, whilst not the most stylish attire, it is a long term investment and if used in horrible horrible conditions, you would be glad of it...there is a reason some of the most hardcore walkers/climbers swear by it.
