    Louis and Staz suggested I should treat myself (true story by the way), and once I’d had a closer look at the Bastion I didn’t much encouragement.

    As I bought this jacket during the hottest summer on record this review is based on first impressions. And the Bastion certainly made a good one when I saw it at Sentinel house, the forest green and coyote brown look really smart in real life, and you can clearly see the difference that 900 fill power down makes, the baffles look very full which only adds to the premium look and feel Thrudark were clearly going for.

    My initial thoughts are that it feels like it’ll be just as warm as the RAB Mythic Ultra it’s replacing, the price and spec of the two jackets is actually fairly similar. The main difference is that the Bastion is that bit more refined in its styling, plus Thrudark hasn't done away basic features for the sake of saving a few grams.

    So far I’d say this is one of the best jackets in the current TD range, during the coldest depths of winter I’ll definitely be reaching for my Palisade Parka, that thing is like a 13 tog duvet its so thick, but the Bastion is the one I'll be wearing most often. The only changes I’d make are a couple more colour choices and potentially the addition of a ‘-40c and below’ Bastion that offers the same premium feel and insane warmth of the Palisade and EOD Parka, but without the extra bulk.
