Has any one used this kind of bag? Never heard of it,saw it was 1.6 lbs and caught my eye. Are these of quality at all?

I've got the Snugpak special forces system, it's a two-bag system, a light bag and a heavy bag and the two zip together to form a bag that's good to down around 0*.
Like any synthetic bag, it's a bit heavier than an equivalent rated down bag, but it's lighter (and was cheaper) than the military issue bag.
I prefer synthetic over down because synthetic will still insulate you if it gets wet, regular down won't. There are water resistant down bags, but they're pricey.
I love my bag, I've camped in it, it's been on deployments with me and I've had it for 7+ years now.
Oh, and Snugpak is a British company.
