Heavy/bulky/costly, but it is a secure fall-winter-spring shelter and has kept me secure for the past year.

I am a side-sleeper, but with the NX-250 I find myself sleeping not quite full on my side, but rather rotated maybe 15 degrees toward the full back position. Still, very comfy.

Am using a HG 3-season 3/4 UQ rather than using the pockets for insulation so I cannot comment on their effectiveness.
