The hoodie is everything you would expect from Rab. It's a little pricey but what you pay gets you a product with efficiency and comfort in mind. I use mine under a Baltoro soft shell or as a baselayer top during active walks and climbs or in the Autumn.
The hood should fit nicely under a helmet or just keep you snug on a windy day.
This is worth the initial outlay of around £70 and is a must for any active walker or climber.
