Familiarity: I've put it through the wringer
It's very warm and comfortable, but unfortunately after 1 year of gently usage it starts deflating. There are no visible holes and it's impossible to detect problematic spot using water because of very small air leaks (should be inflated each 5 hours). I will probably buy regular one, not ultralite model. It's a pity.
