I have one of these. But got it cheaper back during a black friday sale. But IMO, just buy the ECWS sleeping system where you get 3 bags and are 4 seasons. Snap’em all together and they are good to -40f. I’ve camped out in just below zero with them so they are not over rated. I wouldn’t want to be out in -40 w/o the sleeping system shirt/pants/socks and hat but as much as I like snugpak gear, I’ve settled for the blankets for my go bags as everything else IMO is overpriced.
