Katabatic Gear Flex 22°F

Own both the Katabatic Flex 40 and Flex 22—each 900 fill. They are just fantastic, and fit all my needs. Mostly it is warm enough with the Flex 40, but with the Flex 22 you cannot go wrong.

I am 6 foot 3 / 193cm / 95kg, so here are my 5 cents, my history of sleeping bags compared:

• old Finmark/ Ajungilak officially 3 Celsius Comfort—too narrow, in reality Comfort more like 10-12 Celsius: SOLD NOW
• extra wide Yeti Sunrise Comfort 800  XL, egg form XL, roomy but at 1400g much too heavy for UL trekking, comfort max 3 Celsius (even if specs said -2).....SOLD NOW
  

   

  

• Zpacks 5 Full Zip in Long Wide: very warm, like -5 Celsius, but due too mummy cut I found it too narrow and mostly too warm. I also felt this needs care, I found here and there a few single down visible.

• 

  So I bought in addition a Katabatic Flex 40 6'6"/W 900 for summer—perfect fit, roomy for my size, and surprisingly warm enough down to 5-6 Celsius—love it. Even if loft is not too high, I was surprised that it kept me quite warm—close to official rating.

• So, since the Flex 40 F felt much better than my ZPacks 5 F Full Zip, I SOLD also my ZPacks 5 Full Zip for an additional Katabatic Flex 22 6'6"/W 900. I would take this for the EU Alps, the PCT or AT since I trust now that it will be good down to freezing, maybe a bit below with clothes.
• Alternatively I wanted to try the Enlightened Equipment Revelation 10, but I considered "never change a winning team."
• Besides the form, I really like the material, touch, quality, and the collar on top and bottom. Katabatic also comes with two attch systems, but I prefer their unique cord/ clip in the loose position—since this is easy. 

Otherwise I am a big Zpacks fan, but Katabatic was spot on for my needs, quality and touch are a bit more convincing than Zpacks. I bought the 900 fill, but 850 should be good enough too.

Background

UL trekking in European Alps

Excellent quality and warmer than advertised quilt. A blanket style sleeping bag that will truly keep the cold out. The Katabatic attachment system, down filled collar, and draft blocking foot box closure guard you from the cold. When you need some ventilation, the zippered foot box allows you to completely open to a blanket. The options in between are endless, and create a truly flexible sleep system.

After very long research on all kinds of quilts and sleeping bags I decided on the Katabatic Flex 22°F - Wide 6', 850fp HyperDRY Duck Down.

I like sleeping on my side or belly and like to bring my knees up which I can't with a mummy sleeping bag. I feel very restricted in a sleeping bag. I just love this and the flexibility it gives me in case I want to use it as a blanket.

The quality is just super. Pricey, yes, but I always say, cry once and enjoy longer.
