In reply to Dave-the-leg:
Sorry for the late reply.
Yes its made in USA and we are in the UK, yes import duty and carriage are involved. Yes you have to seam seal with silicone.
I stuck my neck out to buck the trend of double skinned tents in the uk.
I was prepared to seam seal.
I purchased twice from Henry Shires Tarptent, Contrail and Double Rainbow.
After sales service is second to none. My Double Rainbow had a manufacturing issue (it was an early one). They sent me a second Double Rainbow FOC.
Do some research on Tarptent and sil nylon to satisfy yourself re durability.
Im a happy camper
