Thermolite Bag Liners

I just bought the Sea to Summit Thermolite Reactor Plus to add to my winter bag for a harsh winter night.

I also have a more bulky bag liner I use for car camping/regular camping.

Has anyone used the Sea to Summit series for winter backpacking?

What’s your opinion about it? I just opened it up and it’s almost a net like material.

I’m wondering if it would just be better to pack a sled with my more bulky liner over using this and being cold mid-winter.

It gets near 0F here on occasion. I just broke into the idea that camping does not have to be seasonal. I enjoy snowshoeing but have not paired that with backpacking yet. There’s a first for everything.

I have the sea to summit liner and it works well. I agree, it does seem very thin and questionable but I think its a good bang for it’s size and weight. However, I will say haven’t camped as cold as 0. I’ve used the liner with my 40 degree bag on nights in the 20s and was satisfied though. Side note, I’ve also used it as more of a blanket when sleeping in warmer weather (70s-80s overnight) and it serves it purpose well for this too.
