I absolutely love my Katabatic Flex 15 goose 900fill. The quality, the warmth, the functionality is all top notch. Worth the money.

Yes for Katabatic quilts! I get a lot of use out of my flex quilt 15 degree with overfill. I love zipping the bottom part to a mummy and leaving the top loose like a blanket. I’ve used it 20-50F overnight temps.

When I did the Salkantay at the end of May a few years ago I brought my 15 degree Katabatic quilt and was never cold sleeping. Might have slept in my down jacket one night that I can recall Edit: also did the Huayhuash which was higher/colder and also slept fine with the same setup

Yes! 100% worth it. I love my Katabatic Flex 15 - I got wide and 850FP down. I’ve taken it in the snow down to the limit and been super cozy. If I could do it again, I’d probably get the 22. I was worried about the temp rating being inaccurate or generous, but I haven’t found that to be the case at all. The only time I’ve ever been cold is when I’ve under planned on my pad and gone with one with too little insulation / too low r rating.

I toss and turn a ton and love a quilt vs a sleeping bag. I’ve taken my Katabatic Flex 15 snow camping down to the temp rating and stayed super cozy in just my base layers. I have the wide bag, so as temps drop below freezing I make sure to use the pad strap system, tuck the extra quilt underneath me, button and cinch the collar and wear a EE Torrid Hood. If on snow, I add a closed cell foam pad to up the r value of my usual pad. Otherwise I don’t do anything special. I haven’t had the issues or had to do anything finicky to stay warm.

Katabatic Flex FTW! I've slept comfortable from 50f down to 7f with the same quilt

I was in a similar boat, I had the Kelty Cosmic 20 and paired it with a heavy liner in most temps under 40f. I was researching quilts with the intention of using them throughout Cali and ended up with the KatabicSwatch. For me the big decider was the volume the zippered footbox takes up (2-3 extra litters). I havent taken it out yet but expect to strap it down when its cold and leave it loose when it warms up and it should be fine. I read the katabics are nicer and have a construction where the down bunches less and stay warmer than a EE or Waratah, hope thats true for the premium I paid. I havent found negative reviews for Katabic

A Katabatic quilt and the Rei Flash 55 would be next to pick up. You won’t need the switchback much, the Neoloft is plenty warm and durable.
