In reply to DayWalker123:
I've had one for about a fortnight now, spent much of this weekend in it. So far, properly impressed. As somebody says, not dissimilar in concept to the Nano air.
I bought it because I open canoe a lot and down just doesn't go well with water (I have several down tops), when I'm floating about taking pictures or whatever. The 60g of Primaloft gold seems pretty warm for the weight, but not so warm you can't be fairly active in it without overheating. The fit is good on my medium, its quite long, and the cut means its both snug for warmth and allows good freedom of movement (for reference, I'm a typical medium, 5' 10", 38" chest, average ape index). In common with all synthetic filled tops I've tried, it doesn't feel quite as breathable as a down jacket, there's just a hint of sweatiness if you start to get hot. I think it would make a good belay jacket unless its seriously cold, but that's not what I'll use it for. Zip isn't two way.
Hood is fine, won't get used much. Has no adjustment. Pockets good for handwarming, maybe a little low cut for use with a harness, but its more likely to be chucked over it I guess. Fabric soft and quiet, which is something I like for nature watching, silent paddling etc.
Nice and light, and not much bulkier than a heavy-ish softshell. I intended to use it for activities where I won't be working too hard - photographic wanders, gentle canoe paddles etc, and as a layer for lunch stops etc, but I like the cut and feel so much it may get worn more than that. It won't replace my bigger Alpkit down jacket for sitting around winter campfires, but its likely to make the thinner Filoment obsolete in some ways.
I went for the forest green, which is a good dark green. Feels built to last.
