Seams impossible to tear though ensure the ground is cleared of very small rocks, sticks etc (thought i was thorough) as i had a small hole wear through in one night. Would buy again just be careful of what's on the ground or buried in the dirt just protruding above the surface etc.
Good groundsheet when weight is not so much of a worry. Service is always first class with ultralighthiker too.
