Flex foot box is adequate. It’s a lot of down and as long as you arent over 5 foot 11 shouldn’t be putting any pressure towards the bottom to make a cold spot. Does make it more versatile in warm temps too Personally felt like my Nemo tensor all season and flex 22 were too warm for Rae lakes in November in freezing night conditions. Felt more comfortable in just base layers flex 22 same pad snow camping in Yosemite in my borah bivvy. I have a 40 degree enigma that I use for 80 percent of my trips but when I need a guarantee of warmth that’s when I go flex 22. But I also think I’m a warm sleeper

I have the Nemo Tensor Extreme, had the All Season before that. I had a Katabatic Flex 22 900fp so yeah v expensive but the Waratah is wider and not much heavier for half the price. The bed setup is awesome for winter, no draughts at all, in summer I just drape my quilt.

Western Mountaineering or Feathered Friends for a sleeping bag. Katabatic or Nunatak for a quilt. I have a Katabatic Flex 22. It is my favorite piece of gear.

I have a Katabatic Flex 22 that is pretty great, if I could only have two quilts I’d get a 20-30 degree quilt and a 40-ish synthetic overquilt for layering purposes. A 30F sleeping bag would roast me in the summer. I would look into synthetic quilts from Mountain Laurel Designs, Enlightened Equipment, or look into making your own.

I would HIGHLY recommend the Katabatic Flex 22 degree with 1 OZ overstuff. Preferably the 900 Fill. I have used it for 5000 miles of hiking and will say it by far is superior.

Ditch the sleeping bags and get a sleeping quilt much more versatile, especially the ones that can open to a blanket. I used the katabatic 22 flex on my continental divide trail through hike and loved it.

Katabatic. You’ll be fine with the 5’6”. I am 5’4” and the flex 22 is A+.

I am not sure if attempting to view it through the sole lens of a fill weight is a good idea. The same rated bag will have different fill weights for the different sizes. I use a Katabatic Flex 22F 850FP in the largest available size and it still only has 18.1 ounces of fill. However, when combined with an Xtherm, I am easily comfortable down to 10F in testing I have done this past winter. Your sleep layering system and sleeping pad are just as important as your sleeping bag / quilt. I would disregard the focus on fill weight and review brand specs and how the community reviews each brand. IE : Katabatic temperatures are the comfort rating, while most other brands advertise by the limit rating. Community reviews typically confirm their status as being warm below the temp rating. That's how you end up with comments stating "My bag is usually comfortable 10 degrees above the rating". That is a company who advertised based on limit temp rating.

Depending on your sizing and which temp rating, I would recommend looking into Katabatic. I have a Flex 22 that I use for winter without concern for temperature as tested down to 10F when paired with an Xtherm. In hindsight, I am more likely to buy a summer quilt than use the Flex 22 unzipped. So consider the non-Flex version for even more weight savings.

I have the same one and I LOVE it.

I use a Katabatic sleeping down quilt and it is SO much better than my mummy bag. If you use a quilt you need to make sure you have a good insulated pad as the quilt won't prevent heat escape to the ground. My Katabatic quilt has straps than can attach it to my pad and it has a zip up toe box for the cold nights. Most of the time I just sleep with it like a blanket, but when it is cold, I put on a hat, zip up the toe box, and attach my quilt to my pad and it works great. For comparison purposes, I do sleep hot.
