A review of any product needs a really good deal of 'testing'. Well I bought the Bastion back in November and it has only now been stored away after a full and long winter use. I live and work in The Cairngorms and the winter we have just enjoyed really put the Bastion to test. I hardly had the jacket off my back. It coped well in very low, high wind chill temperatures. I would only ever need a small microfleece underneath as well as a base layer. On the more 'balmy' days, ie just below freezing, a base layer was all that I needed. I wore it when working hard, with a large snow holing rucksack or walking/climbing fast. I never ever got chilled down despite sweating so it wicked really well. Even with a waterproof shell over it it worked well brilliantly and never overheated or got damp. I never wear soft shells in rain but I did test out the Bastion in snowfall and again it coped well and kept me dry. The hood fits well and when fully zipped up you are nicely cocooned inside. It's roomy enough for a helmet too. My only slight niggle were the cuffs which are nice and snug, not restricting but need a good tug to look at your watch-only a very, very slight niggle! Feels a shame to put it away for the winter!
