Hi All,

I am new to this forum so apologise if my etiquette is not quite there yet!

I am raising this thread having seen the delightfully eccentric Shug demonstrate a modified sleeping bag being used as a pod down to -40F. Whilst I am not necessarily looking to go quite that far - the UK being the temperate place that it is - the concept is appealing in its simplicity and packability.

Has anyone worked on this before? Shug used a V-shaped section to expand a sleeping bag. This strikes me as a relatively simple thing to make?
