Best praise vs top criticism for Nunatak 3D Quilt
Best Praise
+5 pts“I really really like my Nunatak 3D quilt and would 100% recommend one if you come across a used one. But it looks like there's a very low chance of getting a new one any time soon with Jan's [latest update](https://nunatakusa.com/content/33-covid) that they're indefinitely on hold with no ETA.”

What Redditors Say
Best praise vs top criticism for Katabatic Gear Flex
Best Praise
+17 pts“Because the flex fully unzips, buying one slightly too warm isn't that much of a big deal. You'll probably find that youe flex 22 can be used in warmer conditions than your wm bag just cause the ventilation when unzipped.”
r/Ultralight
ViewTop Criticism
+7 pts“OP is 6'8". The flex (or any Katabatic for that matter) will most likely not fit. I'm 6'6" and when I had Dan Timmerman make a custom quilt with 80" length it was a game changer. I can now actually tuck in nicely and fitting for me.”
