Daniel Mauswrote a review of Rumpl Down Puffy 1P Blanket on November 17, 2019
Familiarity: I've used it several times
These blankets are magic! A lot of warmth in a small light package. These are great for hanging around the campground especially in areas that you can’t have a fire! I would caution the use of these around a fire because any spark will definitely burn a hole in the Lightweight fabric. I use this blanket to give a bit more warmth on cold nights.
There is also a loop on the edge of the blanket that you can pull the other corner through to wear it as a cloak. Not sure if that is what the loop is for but works great.
Fabric is similar to your down jacket so you definitely want to be a little careful not to tear it.
