Slohike,
I don't have the original invoice. I bought it around Christmas 2010 from Ultralightoutdoorgear on the internet. I didn't save the communications between us unfortunately.
It hasn't had any leaks and it has been used on 14 nights. Bought it for my other half but she doesn't like it so it's just hanging in the wardrobe.
She says it makes her hips ache.
She says £35 and that will incl P&P. UK.
