He's a bit of a WRT virgin (and this will be his first Bivvy) and about the only bits I don't have doubled up are a Sleeping bag and Mattress
I suggested a AlpKit Mat would be spot on, decent size, weight and cost but they are no more (also Bag)


So bearing in mind we need it this week and he may not get the use out of the gear to spend mega money on stuff
What Mat is a good compromise between cost / size / weight?
Same question for Sleeping bag??
