In reply to An Triubhas:
The Bastion is a weird one. It doesn’t seem to fit quite into any category of jacket that I’d want on paper but I wear mine all the time, and I’ve got a lot of insulating jackets.
It’s no good as a belay jacket (in my opinion but I believe Nick Bullock uses his as one) as the hood isn’t helmet compatible and the sleeve cuffs are too tight.
However, it’s great as warm go-to jacket. It’s warm for its weight, has a good cut and is weatherproof. I wear mine belaying, as a warm layer in the sac when walking/camping, I live in it when I’m in my van and wear it to the pub. I’m even considering it as an insulated shell for cold weather winter climbing.
The shell does set it apart for the Nanopuff/Xenon?Zephrus competitors. It’s far more weatherproof that my NorthFace Zephrus so instead of thinking I’ll get wet but stay warmish I know I’ll stay dry and actually warm.
