sleeping bag comparison…

Aight had a read of a pile of sleeping bag threads here. Looking for a second sleeping bag. Long story, bought a new kuiu 0 bag 12 months ago, wicked bag, but very much a winter bag for weight, packability and temp rating.
I’m in need of a bag for roar/spring hunting that packs small and is as light as possible.
Living in central Otago so want one that will be ok in tail end of the roar where below zero is very likely.
I was about to pull the trigger on a RAB Mythic 400 but have seen the Sea To Summit Spark SP3 popping up here and there. On paper they square up but I am wanting to know if anyone has hands on comparisons of them both? Is the RAB worth the larger price tag? Or if there is something as good worth considering that’s readily available in NZ?

Cheek the one plannet specs bro i got one of there that was half the price of the rab and specs were on par with each other. Was a couple of years back now tho

+1 for one planet.

love mine

I have 3 Rab sleeping bags, well worth the price. Have a look at the mythic ultra range aswell

I have a mythic 600, because I get bloody cold when i sleep.

awesome bags but be aware that I'm 6'1 112kg and i wouldn't want to be any bigger. if you're a big unit I'd see if you could drop by somewhere and give them a trial fit.

I have a macpac dragonfly 400 which is 780gms and has been a great lite-weight option to my 4 season heavy bag.

Ms got a rab, always small ount of down around after a night sleep, I'm using a 15yr old sea to summit , still happy. Both are good bags. Rab can be bought in Europe for1/2 price. Lots of stores will post

What he said, i got a One Planet Nitrous -3 and very happy with it , packs down very small, weighs about 600 gr. Been plenty warm enough so far , but yet to test it in colder temperatures.

Re RAB, a few years back I pulled the pin on a Neutrino Endurance 600, was a high spec & very expensive buy iirc retailed for $1300 - 1400 I'm a very cold sleeper so wanted a decent light weight - packable bag

It's a very nice piece of kit but I wouldn't rate it as twice the bag of a Macpac at half the price ( if you get what I mean ) It's always easy to say the expensive option isn't twice the product but in this case I think the more budget bags work fine, I have a 20 yo Katmandu down bag ( I use for a truck / crash out kit ) I got on sale for like $250 & while bigger n buckier theres fuk all difference in performance. I also have a Exped ultralight which is a great bag so could be worth a look ( being UL the zips are pretty lightweight though )

For bags it seems to come down to down loft n quality & a decent theremal liner helps

Exactly where I was at with the decision mate. Between the one planet, seas to summit and rab compatible options I really needed/wanted to know if the rab really was worth close to double the price.

In short no for rab. Built quality no better than my S2S.

Keep in mind with the liner some of them weigh upto 400grams and you will get far more warmth from adding 400g of down into a bag (fill weight) then a liner will do.
I run a silk liner for keeping the bag clean tho

My two cents….my Macpac latitude 700 died a death in the bath tub when I tried to wash it, the baffles gave way, was only 6 years old but had excellent customer service from Macpac who refunded the purchase price as the model was discontinued. Bought a Rab Alpine Pro 800, at the time I compared specs and pretty sure the Rab on paper at least looked to be the warmer bag, but in the few times I’ve used the Rab I’m convinced it’s a colder bag, still warm enough but just not as warm as the macpac and with small details like a stitch seam standing proud 2-3 mm the length of the bag. If I could have found a Macpac with a 3/4 zip to split and use as a duvet for me and the dog I would have preferred MP. The Rab is good, I just think in this instance MP was better.

I also have the lattitude 700 and its a nice bag but a tad on the heavy side at 1.5KG great for winter but too heavy most of the time.

I have an older model of one of these.

Pros. Great shoulder season bag, not too expensive, can be zipped right open.
Cons. A bit heavier than the flash ones.
I always use a silk liner and if the temperature really drops I will wear clothes inside it. I usually end up using it with the zip part open.

I run the seas to summit Trek II and could not rate it more. Four years of big missions and still going strong.

Its light, warm, and plenty cozy. I did once sleep in the Greenstone valley in the middle of winter (cold enough that bootlaces froze solid). I have since obtained a better sleeping mat and that solved that problem. It turns out they have quite light insulation on the bottom so you need a really good mat with them to avoid loosing heat to the ground.

Also a fun fact is that if you have a wife/gf and they get a sea to summit bag you can zip them together as the men's and women's ones have zips on opposing sides. They can also be unzipped to use as a quilt, I do this a lot in summer when it gets warm.

A really good bag, especially when used in tandem with a thermal mat and a liner to beef it up for those colder winter missions.

Another vote One Planet. Have the Cocoon and it’s been great. Packs well and is easily warm enough. Pays to get their 800+ loft option as obviously it’s lighter for the same warmth.

No mention of the domex halo, wow, I got one when they were all the rage 3 or 4 yrs ago. My how times change...haven't had an issue with mine yet btw

Something not al have is a 2 way or seperate zip to be able to open and poke only your feet out to put on boots etc
Even go for a midnight wander in it.

+1 for the One planet Cocoon 800loft.
Very small packed size (w/ a aftermarket compression sack) and light weight.

Two bloody cold snowy nights last week where I was warm as toast in the Cocoon. I did wear my down jacket but it wasn't really needed, it just meant I could have an arm out.

way back when I worked in sports n camping store we had visit by rep of one of the big companies..possibly fairydown??? long time ago now...was shown that you can move the down around in sleeping baf baffles by doing a sort of karate chop motion to move n shake it along baffle from top to bottom...the bags had baffles running around bag of course.... might be solution to your woes.more on top in winter for warmth and more under neath in summer so not so warm.

Pretty certain you will find those compression sacks will probably reduce the lofting ability/ life span of your down over time....

You only have them compressed while carrying them in your backpack. They come with a large mesh storage bag.

Aight looking intently at the one planet bags now simply with the price and weight, and my shrinking budget lol.
One question for the guys rating then, what’s the difference between the Nitrous and Cocoon? Can’t find bugger all between them despite weight and price. Specifically comparing the cocoon -5 and the Nitrous -3

I've got the spark 3. Went for the Long version but probably would go standard length next time.
Amazing warmth to weight ratio.
Only thing I don't like is the small zipper, easy to get it caught up but that will probably be the same on all light bags

Cheers mate. Yes I did see the spark uses a ykk 3 zip vs the one planets are a ykk 5 zip so a bit fatter. Also have an interesting zip guard on them but buggered if I know how effective it is.
Everywhere seems to be almost sold out of spark 3 bags which is a good sign I guess. Still an option when comparing it to the cocoon -5 but I also need a new thermarest mat so money is in the equation too hahah.
My big one is to save a bit of weight but really pack size is key too.

While you wait to find the right one and aquire the budget needed you could use a liner in your bag and a thin piece of mat (like the thin under floor insulation foam with the foil one side) to boost the warmth of your current set up

Current set up is too hot not too cold hahaha.

I went with one of these when they were on special.
Light and packs down fairly small.

I have a couple of Rab bags.
Had the halo, didn’t rate it.
Had a macpac, was good but heavy
Moved to a Rab mythic 600. Love it!
Had it in -12 and still been warm.

I picked up a Rab Mythic 600 from a Facebook tramping/outdoor page for about half new price. Lightweight and warm as anything. A liner in minus 10 was too warm for me. Far too hot for hut use.

With the xthurm you can run a less fill weoght bag for the same warmth remember its about the total sleeping system not just one piece

I have the same bag for everything except winter, has been bloody good!

+1 for the one planet sleeping bags.
I'm very happy with mine (-3, using appropriate thermal liner depending on season).
On paper they just seem to be about the best value for money proposition on weight>packability>warmth offering out there.

@WildBrad
I bought mine from TreknTravel website (Hamilton shop)
https://trekntravel.co.nz/shop/one-p.../#&gid=1&pid=3

The Nitrous - only half a hood, ultra lightweight, it's heaviest and warmest model -3deg weighs 600grams. At <$600 The less warm models weigh less and are cheaper.

https://trekntravel.co.nz/shop/one-planet-cocoon/
COCOON - Full hood, zips from top or bottom. Temps and weights vary depending on model. I got the -8deg, small, 800loft weighs 710grams- $660

Another option for purchase is Southern Adventures in Invercargill

Ask for Craig

Southern Adventure is a fantastic shop, friendly helpful staff, great range and awesome deals.
