The warmest piece of clothing I have, bought for a trip to Kiruna (200km inside Arctic Circle) and Stockholm when it was, er... a bit nippy
outside. I think I paid well north of £150 quid for it. I asked, curry style, for the warmest thing they had and this deffo fitted the bill.
It's an easy L (I am 1.85m 44 chest and not tight), has two external zip pockets on each side and generous pockets on inside. Gloves and goggles easily stored. Long enough to cover bum.
It's taking up space in the wardrobe and I've worn it about half a dozen times since Sweden because it's too warm for me, on anything but the coldest of cold days. You'd have to take it off inside anything other than an igloo. I've got loads of other kit that needs hanging up that will get worn ahead of this.
Comes from a smoke-and-pet free home. The white specs on collar are bits of down. Comes with detachable hood (IIRC, also down-filled).
