Enigma 850FP 40F

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 did the PCT with a 10 degree enlightened equipment enigma (quilt with sewn footbox) and it's a way more comfortable sleep than my mummy bag days. It's the #1 bag in that survey for a reason. It's now lasted me 12 years and about 200 nights and is still in amazing shape. I also have their 40 deg quilt. When outside The bag never leaves the tent, other than while in the stuff sack. At home store it in a oversized large storage bag or hang it from a hanger in your closet and occasionally (like every couple months) store it the opposite way. I imagine I'll get another decade out of it.

I just custom ordered an Enlightened Equipment enigma that's Xwide, measurements says the Xwide is 68in wide. Might be what you're looking for.

I bought a used quilt on marketplace. Enlightened Equipment 40 degree.

There are many…from REI house brand, to more expensive (hipster!) cottage brands like Enlightened Equipment, Zpacks, Zenbivvy, Katabatic etc etc. I have 2 Enlightened Equipment ones - chose them as they are cheaper than some other niche brands, lighter than nearly all others, and have good resale value. I have a summer 40F quilt and a 2 person (!) 20F quilt.

Maybe do what I did, keeping my current 20 degree quilt, and possibly add a 40 deg standard width quilt for warm weather. Its noticeably smaller packed, and a few ounces here & there add up. Both are EE, which is fine brand. Any down quilt shouldn't be stored compressed, but OK to pack. I'm in north Georgia & there's times a warm quilt is overkill. I try to pack ultralight; not only because I'm in my 60's, but also because I have a congenital disability that makes weight-bearing painful. I probably have no business backpacking, but I'm too stupid to realize it

The manufacturer rating on the bag is usually a survival rating and it’s best practice to increase that number by at least ten. I have a 20 degree kelty bag that works really well down to like 35. I also have an enlightened equipment quilt that works well at its listed temp of 40 degrees.
