Timmermade - Coati Quilt 900fp

Also consider the skirt quilts from Timmermade. I have a Serpentes made skirt quilt style with a 30/20 split rating (not listed on the site, you have to ask). Essentially a Coati with 7d fabric and 1000fp down. It is amazing and so versatile at about 16.8oz. I added shock cord to the channels of the draft skirt for edge tension. If it’s really cold, I’ll cinch that down and it keeps out drafts and acts like a false bottom bag. I have it with a 20deg rating in the bottom 2/3’s and 30 in the top 1/3. I found that when I got cold when sleeping my legs and feet always got cold first. And I could augment my torso with a puffy jacket if needed. I’ve taken it into the teens comfortably with alpha leggings, and alpha top under a sun hoody (I would say I’m a warm sleeper). And the very best part is no messing around with pad straps. You just tuck the draft skirt under you.

There is not a whole lot out there as far as reviews. I believe the Timmermade Coati is the only one out there. But basically there is a 6” flap of fabric at the quilt opening to seal off drafts. You manipulate it with your hands and tuck it under you and your body holds it in place. Or add shock cord to the channel for edge tension like the offerings from Nunatak, UGQ, or Katabatic. But as I understand it from Dan, the skirt quilt edge tension is better as the tension is applied to the skirt, not a down chamber, which can compress that down. One of my favorite things about it is getting the neck opening snapped closed. On my other quilts, I always have a hell of a time with this since the quilt is strapped to the pad. With this, you just snap it in front of your face when you’re outside of it, and slip it over your head. FWIW I also have a Katabatic Grenadier for winter and that thing is amazing too. Seals out drafts so well and is ridiculously lofty. For anyone who doesn’t want to wait weeks and weeks for a quilt I would quickly push them in the direction of Katabatic. I have heard the Timmermade lottery is extremely difficult, but I somehow managed to win on my first try.

You make a good case for functionality with the 2-temp-range construction of many bags. I had not realized that was a thing. I would agree with you that pad straps are bunk. I gave up on those years ago. I tend toward quilts that have false bottoms or false bottom flaps, like [this one](https://timmermade.com/product/coati-quilt/). Curious that this same maker also does bags that are kind of a hybrid with a quilt, like [this](https://timmermade.com/product/wren-false-bottom-sleeping-bag-narrow-torso/), or even [this](https://timmermade.com/product/serpentes-false-bottom-sleeping-bag-mummy/) which take the false bottom further.

For the sleeping bag I’d recommend a zpacks, timmermade or cumulus 30f range sleeping bag you could push into much colder temps wearing alpha 120 bottoms, down jacket, and down foot booties inside the sleeping bag. I’ve used this combo of clothing to push my 12oz 50f sleeping quilt down to 20f comfortably. If you plan to camp mostly in the summer I’d get the 50f bag and just wear more clothes inside it to push temps lower in fall. I switched to this technique and was able to reduce my pack size a lot and half the weight of my sleeping bag and its bulk. It works well since I’m already taking the alpha pants and down jacket anyways so I might as well wear them and save weight on the sleeping bag. The wind makes the biggest difference to me for how much insulation I need at night. For High Wind below freezing a windproof bivy that can fit over your pad and quilt makes a huge difference to your overall warmth and stoping drafts. Many UL quilts with 7D fabric are not very windproof and even a 20f bag can feel very cold at 20f in high winds. I like to summit camp and it’s often very windy above 6000ft. For the sleeping pad I’d recommend the thermarest nxt https://cascadedesigns.com/products/neoair-xlite-nxt-sleeping-pad?srsltid=AfmBOop1YJvl8n8oPU1vCNvveJ5sopEYhuUIcb1ORgJmz5-Sc-vxRd-W If 6.1 and the wide thermarest fits me but is still small. It packs down very small and is the most comfortable and insulated pad for the weight that I’ve tried yet. I have slept at 10f in the snow and been fine with it. You can also pair it with a gossamer gear thin light foam pad and gain more R values for freezing temps.
