It's the orange survival bag from Coghlan's
It provides instand protection against wind and rain.
The cold in Holland isn't that much, so additional thermal protection isn't a priority.
I also have some emergency space bags, but I prefer the orange bag because it's a lot ness noisy, it's tougher and makes a good ground signal and/or tarp
I'm also thinking about a orange tube tent. Is it any good??
