Awesome
The puffle expander gives the puffle increased flexibility. I recommend it

Great for those of us who need arms free
My only complaint with mummy sleeping bags is having my arms trapped when it's fully zipped closed, making it difficult to get out quickly. The extender combined with a Puffle gives me the extra mobility at the shoulders. And it makes the Puffle stay in place when wrapped up sitting at a bench.

Unfortunately I have not used the expander yet. Due to WNC damage. Hopefully next season we will be able to. But it is well made.
