r/UltralightAgonizing over a sleeping bag choice for 0°C

Take a look at Rab neutrino 400, or consider cumulus quilt 450 with some sort of down hood and/or down/climashield apex socks. Thermarest xtherm pad is great.

r/hikinggearSleeping bags for northern climate - what to buy?

April through October is my 400-time. In the end it really depends on what your personal comfort limits are and at what temperatures you would switch to the winter bag. I imagine the Norwegian coast is a bit warmer during winter than the Swedish coast, due to being more maritime? Regarding Rab: I have used the Neutrino 400 now during six seasons (this is the seventh) and I am really happy. It probably has lost a bit of fluff but that is to be expected after that time. Washed it once because I didn't use a liner in the beginning, but otherwise used always a liner, always hung it out after a hike and stored it in the cotton bag. If you have the money, go for it! They seem to have added a Neutrino 500 to their range and that would be my choice today, between the 600 and the 400. Otherwise, they also have a 650-cuin product line (cheaper but heavier) which is probably just as good.

I've used a overfilled neutrino 400 in Kyrgyzstan last summer. Sleeping around 3600m in Ala archa. Never closed the zipper.

r/wildcampingintheukSleeping Bag Advice: RAB Neutrino 400 vs Sea to Summit Spark – One Bag to Rule Them All?
10 months ago

I’ve owned a Neutrino for years now. I also use a silk liner and a Thermarest pad. It’s been a thoroughly dependable sleeping bag. Nothing has gone wrong and I’ve found it plenty comfortable. I use it in Spring and Autumn and have a quilt for the summer and a bigger bag for the winter. Never used the S2S one, I had a look, it seems decent too. I suspect either option would do very well for you. But my experience has been a good one with the Neutrino.

Okay that pad is not very warm or particularly comfy so it’d be a really bad idea below freezing. I once had one a lot like it. It’ll do okay on soft ground in reasonable weather. So I’ve given your quilt some thought and come up with an answer. Sierra Designs Nitro 800F 20°F Down Quilt. It’s very reasonably priced for an 800FP (fill power) quilt and it has some neat features that makes it good on the colder end of the scale. It weighs 760g and should be comfortable at above freezing temperatures. Water resistant down will help it last and dry out faster. You can partially lay it over you in summer, move it fully over when it finally gets cool enough. You can use it even a bit below freezing if you wear an extra layer or two (but don’t use your current pad). I know Sierra Designs well and they’re one of the best of the mid-market for sure. So in terms of a decent lightweight quilt to cover as much of the year that one item can, I think this is the best value for your money. [£230](https://wildbounds.com/products/nitro-800f-20-f-quilt?variant=39416617894055&utm_term=ShowSignup&gad_source=1&gad_campaignid=17178698583&gbraid=0AAAAACpiRygrPP7SwmYLQcl_VgOoH4Uoz&gclid=Cj0KCQjwsNnCBhDRARIsAEzia4CgumdRaYZtEkx9Wba4cxGtCbuu2QuCQzjWpv8UiNzPkIcXMqDGROUaAhySEALw_wcB) is the lowest price I saw on google, but check around if you’re gonna go for it. I suspect the price might sting but trust me with sleeping bags/quilts, if you want down, then quality filling is just expensive as a commodity. So decent down bags just don’t come cheap. Down is much warmer per gram and compresses smaller than any synthetic filling. If you want light, down saves you a chunk of weight. The trick is to buy the right thing for your long term needs and then look after it. My 3 season sleeping bag is a Rab Neutrino bag I’ve had for over 10 years now. I’ve slept in it over 100 times. I’ve always dried it out if it gets moist, never got it dirty or soaked, always compressed it the bare mininum in my pack (I don’t use a compression bag), dried it and aired out thoroughly at home and stored it in a loose sack in a wardrobe. It’s still as good as the day it was new and I could sell it for something like £150 on ebay. So if the budget is tight, buy a decent quilt in a little used condition if possible 2nd hand on ebay. But I’d urge you to buy a decent quilt that’ll really do the job. There’s a [Thermarest Corus](https://ebay.us/m/BVJmho) on ebay right now, this model is a bit warmer than you want and it’s a long size which you don’t need. I didn’t see anything else right now but if you have time, save some searches on ebay and get alerts when ‘camping quilts’ or ‘ultralight quilt’ are listed. Hope that’s helpful mate

r/wildcampingintheukAlpkit pipedream 600

I have the Pipedream 400 and I have mixed feelings. It is fine, though it doesn’t loft that well and I take the temperature rating with a pinch of salt. For the price (on sale) it is worth the money, but it won’t perform as well as more expensive bags. Also if you have a broad shoulders or large chest you may find it a bit restrictive. I have a 46” chest and find it less comfortable than my other bags. Edit: just to be clear I think it is a good bag for the money. I don’t want to discourage you from buying it. And the 600 will presumably have a less pronounced lofting ‘issue’. I would also check out other online stores for sales of other Brands. I managed to pick up a Rab Neutrino 400 for 40% off from a small online store. Second hand bags are also an under looked option. People buy camping equipment and often never use it. With a bit of hunting and luck you can find bag that are nearly new or even never used.
