>>2293289Because I did the (likely) same thing as you and looked on Amazon a bunch until I found this quite interesting blanket, I'd say it was a good purchase. It's a VERY large wool blanket that I use for both indoor and /out/door. Excellent to cover the top of your bedsheets in winter or your sleeping bag elsewhere.
A second one a bought as a cheapo-throw-away camping choice was too small in my opinion, but of course that could be what you'd want in your pack.
TL;DR:
Seems pretty good, you probably also believe wool is quite the super-material and makes a nice camp-cosy/warmer in a pinch. Use if you're willing to sacrifice A LOT of space in your bug-out bag.
