Just thought I would share my little creation with you. I have used a combo of a dutch army poncho, some old tent poles and a US army ground sheet to create a shelter that weighs less than a kg but is lovely to kip under in nasty weather.
Like it, but I've tried biking with a poncho
It was windy and it was like cycling towing a parachute, never again
Caused so much drag I took it off, preferred to get wet instead
