i have been looking at the website and i have been told to look for a tent with a hh of 3000 or more but i can't find anything about that on there. all it says is
Like all Quechua tents, the waterproofing has been particularly well-developed, approved in lab tests (WHOLE TENT in a shower of 450 litres/h/m2!) and on field tests. (450mm PU coated polyester flysheet, 135gpsm 2000mm polyethylene groundsheet.) A breathable polyester bedroom under the flysheet means you aren't in contact with the condensation that forms naturally on the inside of the flysheet.
