Blue Sea to Summit poncho tarp,
similar to this but the previous model.
Size is 135 x 2500 cm. I'm 170cm tall and it fits well on me with an overnight pack.
Weighs 334g (including stuff sack), easy to fold and pack away.
Full disclosure: I previously bought this from Moondog (
see this thread). He had never used it, except to take photos. I bought it for my partner, but she fell pregnant and did not end up doing the intended walk it was bought for. In the end it was taken on 2-3 trips but never actually used, so it is still essentially like new.
Happy to sell for any reasonable offer, PM me if interested.
