Capestorm Atlantic Sleeping Bag

Hi, hope everyone is doing great.
My first post on this forum.
Does anyone here have some experience with the following product?
Capestorm Atlantic Sleeping Bag

By the touch of it, it looks fairly thin with 120g/sm microfibre.
However, its temperature ratings: Warm +7 degrees Celsius, Transition -2 degrees Celsius, Extreme -7 degrees Celsius.
I like it because it's very compact and light weight (less than a kilo).

My question is can 120g/sm really live up to to the claims?
This product looks like (temperature range wise) equivalent to FA Amplify 1500 (much thicker and pricier and heavier).

I am confused about which one to get.

Thank you.



 

I would be a little sceptical of those numbers.

Having said that, for my first few winters hiking in the 'Berg I used a similar Capestorm bag (Microcore 130, possibly) - if I remember correctly its comfort rating was 10C or 12C and extreme was 0C. On one particular hike the temps dropped to around 0C or a little under each night, but I was comfortable - in a tent, wearing thermals (it's probably worth mentioning that my girlfriend, using the same bag, was not comfortable). I once got a little chilly in Upper Injesuthi cave (no tent), but other than that was always fine.

I still use that bag for any hiking/camping where I don't anticipate the temps dropping into single digits.

If you sleep warm, then I would say it is suitable. I am still using a First Ascent Ice Atom bag that I purchased 15 years ago. It is tiny and lightweight. Although it is rated to 5°C and 2°C extreme, I have used it slightly below freezing with an inner liner and wearing a thermal layer and have been fine.
My wife on the other hand needs 3 sleeping bags, covered in a Yak fur and a hot water bottle to keep her warm

Thank you all for your replies.
I ended up buying the bag to give it a try (I like the fact that it's so compact, and lightweight).
It fits perfectly in the sleeping bag compartment of my 58 liter Kestrel along with the sleeping pad leaving lots of space in the main compartment.

In Gauteng, last night and this morning was chilly. To create a realistic scenario, I left the wall fan on on highest setting (pointing towards my lower body).
The bag seems very well insulated (not sure if it's the lining material or the microfiber, or both), I could barely feel any of the air of the fan. It was very warm inside the bag and I did not struggle to sleep.
Usually I need two comforters in a similar situation with fan on to stay warm.

So, I am happy.
I know in the mountains it'll be a completely different environment. However, I think it'll hold, and liner would even be better.
