I can't tell you. I bought this tent for multi-day hikes and am totally satisfied. The only "flaw" is the thin floor, so we recommend a footprint (ground sheet) for the tent. However, you have to save material somehow to get to the really low weight. Conclusion: Ideally suited for multi-day tours and off-road bivouacs in good weather. It can withstand light drizzle (ground sheet recommended). For heavy rain, I would go for a stronger, heavier tent.
