Waratah

I would also recommend a quilt paired with a good sleeping pad, which would be different if you are hammock camping. I'm not familiar with hammock camping, but I think you would need an under quilt and an over quilt. The under quilt, like a sleeping pad, is also essential in keeping you warm. Having said that, for ground sleeping, I've had a 30F degree synthetic Enlightened Equipment quilt for a few years and often found it too cold. It's also very large and doesn't compress down very much for the warmth it provides. I've retired it to lending to friends and car camping. I just picked up a Neve Gear Waratah -8C which I pair with a Nemo Tensor All Season pad. I just snow camped in 30F / -1C with it. I do wear a full set of down PJ's (overshoes, pants, jacket) and I do sleep cold, having issues with cold feet in the past. With the -8C and full set of down I was plenty warm and had no issues. I could have probably gone down to the advertised -8C and been okay, slightly out of comfort. For summer I'll use the Neve Gear Waratah UL paired with a Nemo Tensor Elite pad that drops around 500 grams (haven't weighed it yet). If I recall both the -8C and UL quilt were within specifications for weights but will double check later.

I just got back from snow camping in -1C weather, first time using my new Waratah -8C. I also sleep cold but was completely fine with generic down booties, pants, and jacket with a Nemo Tensor All Season pad with a foam pad underneath. I could have gone a few degrees colder too without issue (maybe down to -5C). I plan on using the -8C quilt for fall/winter/spring and bought the UL version for summer camping with a Nemo Tensor Elite, which shave at least 450 grams. I'll also not wear my full down (just booties) when not snow camping. I previously used a 30F EE Synthetic quilt (Revelation Apex) but found it too cold, heavy and bulky, but will use it to lend out. I'd recommend the Neve Gear -8C. I read about quality issues around the ends of the threads but mine was fine. I haven't had any super high end quilts, but happy with this one for its price. I was also a bit worried about material, specifically the 7D on the UL but it actually feels pretty good. I would also go with regular width. I'm 5'10", 180lbs and was fine with it. You don't want to go too wide which would be wasteful - I went wide on my EE quilt and regretted it.

Neve Gear Waratah is currently the best price on a high end quilt IMO. The 20° is like $260 and doesn't seem to cut any corners on materials and design. I think quilts are 100% worth it when outside temps are above freezing. Soon as it hits below freezing, I prefer a mummy bag.

Durston X-Dome 1+/Terra Nova Pioneer Compact 2 with a Nemo Tensor All Season and a Neve Waratah -2C quilt. This combo does me all year round, with varying combinations of base- and mid-layers to boost warmth depending on the temperatures.

I have the Neve Waratah quilt(-2C version) and prefer it to my Sea to Summit Spark sleeping bag. I use it with the Therm-a-Rest NeoAir XTherm NXT sleeping mat. The mat is a R 7.3 so might be too warm for you but I’m a cold sleeper. However that being said I have used it in summer in the Blue Mountains and I didn’t overheat but I’m not sure how it would go if the weather was a lot warmer.

The sleeping pad is fine. Could choose a ccf pad to save some money, but many people can't sleep comfortably on them. Also not as insulated. I agree the tent is way too heavy but I'd suggest looking for a lighter sleeping bag or just going for a quilt. Nevegear is a reasonably good deal, for example, that would cut well over a pound for about the same price or a bit more money depending on which you buy. Or, if you want to go the total opposite direction and buy something more 4 season worthy, Paria has a new 0° 800FP down bag that is $20 more than this one and less weight even with the much better rating.

Look into Neve Gear quilts too. They seem to have excellent quality for the price. I placed an order for two of them myself a few days ago and I'm excited to test them out.

I just got the Waratah -8C and love it. It's my first quilt and l chose it because I sleep cold too and the way the straps attach up the sides allows the quilt to tuck under a bit and eliminate drafts. Additionally, it opens up completely for the warmer nights. It's also rated for female temperature ratings which means it's warmer than similar ratings of other quilts. Having zero buyers remorse!

Well I don't have experience with the katabatic and haven't touched one. But I did research them and the strap system was the selling point for me along with the cost all other things comparable. I feel like the quality is great. Like I said zero buyers remorse. I was coming from a Kelty Cosmic Ultra 20 mummy bag which I felt underperformed this winter. I shaved almost a pound of gear weight and at 30 degrees F (the coldest I've had the waratah out in so far) I was much warmer than I've experienced being in the Kelty, which I would have had to pair with a fleece liner at that temperature.
