Solar sp c-tech sleep system questions (26 posts / 8,744 views)

I'm thinking of getting the mk 2 Solar sp c-tech sleep system and have some questions which hopefully current owners could answer .

Can someone tell me the season rating when the outer bag is taken off ?

What is the weight of the system with the outer bag taken off ?

Is the outer only waterproof when in full 5-season mode - ie, if the outer bag is taken off is it still waterproof ?

Many thanks

I believe it's a 3 season / 5 season split... Depending on which of the bag or bag(s) you have zipped on. It also has a "fitted sheet" type thing going on

Couldn't tell you the weights...no idea.

Both bags are made of the same material, so I would assume their waterproof rating is the same?


It's a heavy bed and built like a tank. But my god it's comfortable, and I'm someone who would ordinarily hate memory foam.

No complaints! I lucked out and got one for £350, but would probably have paid RRP for one now I've had chance to appreciate it's comfort.

You got the standard or wide? I have a wide version of the previous model and debating getting rid for the standard just for a bit of extra room, weight saving.

Think the new mk2 standard is a bit wider that the mk1 standard was

I currently use a fox flatliter mk 2 which weighs in at 13.5kg plus about 3kg for the thermal cover . I believe the solar is 19 something kgs so about 3kgs more fully loaded . As I'd probably only use the outer bag autumn / winter it would mean for the spring / summer it would be considerably lighter .

Thanks

as above its 3 + 2 season although i got mine in may and took off the top section straight away and tbh even just the 3 season section is too hot, only the top 2 season section is waterproof as i found out after leaving a window up during a big downpour lol... luckily it was the foot end and wasn't too bad.

I suppose you maybe could just zip on the the top 2 season waterproof section but not certain.
It seems wide at 90cm(standard size) and is taller than my previous benchmark bed but is the comfiest bed i've owned

Is it possible to remove both bag sections and then just zip the 2 season section back on?

A 3 season bag would be way too hot for me at this time of year.

I'm currently using a Fox Duralite which I have a 1 season summer bag for so I'm looking for something similar ideally.

Correct.

As it happens I've also got a Duralite. You won't be disappointed with the solar (apart from the difference in weight)

Sleeping bags aren't rated in seasons anymore. Everyone is different when it comes to whether or not they run hot or cold. The bed is the best bed ive ever used by along way. I've slept comfortably down to zero degrees in the single layer. With the outer layer on id be able to sleep down to temperatures that would be pointless fishing in as the lake would be frozen. If you have bad circulation then it would be perfect. It's heavy but I have gotten my wide version on my barrow so depends on how fit you are on how you can transport it. Ive used it sleeping in the back of my van when im working away and it very comfortable. Wouldn't buy any other brand of chair or bed now.

Just weighed mine as on a weight limit for a france trip, the system without the outer 2 season section weighed 17.5kg, yes heavy but very comfortable

Did you get one in the end
I've the same Fox Flatliter Mk2 standard
Did you go for the standard size which I think is slightly bigger than the Fox
Cheers
Are you sure?
