Very light & warm everyday jacket
Reviewed By James, 24 Feb 2014

I was searching for a jacket that I could wear most days for my job, I work as an ecologist so am often outside. I needed something which would be warm yet allow me to walk around, bend down without over heating and having to take layers off...this is where this jacket was perfect! I usually where a tshirt and thin fleece/top underneath and its ideal. Even with a waterproof over the top its still very flexible and warm. I had a look at down jackets but as the jacket was going to be in regular use I decided for a synthetic one, its shower proof aswell and the material is more hardy than the usual down jackets, all in all a great jacket!



A winter favourite
Reviewed By Gary, 22 May 2013

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!



Brilliant, Warm and Light
Reviewed By Andrew, 18 Apr 2013

Great item of kit. Very light, packs down small. Warm enough to wear with just a tee shirt even in a good blow, but room to have a light weight fleece on under as well for extra warmth. Fits well with good arm length.



Superlight, warm, well made, good buy
Reviewed By Robert, 29 Mar 2013

Replaced a heavyweight fleece/softshell and rock solid hardshell with three lightweight mix-and-match layers including this Bastion. Gives much better flexibility. The Bastion does the job - when stopped and cooling down or in a brisk wind. Packs down to nothing.



Fantastic Jacket!!!!!
Reviewed By JIM, 19 Sep 2012

Brilliant item of technical clothing! A great alternative to Down Insulation (no annoying feathers poking out!). I wish I had purchased one earlier rather than continuing to use goose down!!
