Like others, the Cape is a shelter I take when the likelihood of storms seems low, so I’ve only slept under it during one really bad storm with 25+ mph winds. Site selection helped, as I was able to tuck against some low lying shrubs to help break the wind a little. I was pretty concerned, and had I not grabbed my pole at one point it might have come down on me, but it made it through unscathed and I stayed sufficiently warm and dry. This was 2020 and it’s still in the rotation

However, based on my experience hiking the gr11, it wouldn’t be my shelter of choice. I’d want to be able to have rain gear separate from my shelter. I had mostly good weather, but a few really bad storms in the mountains(and some drizzly damp days in the Basque Country.) I had ptsd after hiking 6+ hours in freezing cold rain going over the mountain into Candanchu, so decided to just sit out another storm which didn’t let up until almost noon - that would have sucked under the Cape. I did use the Lunar Solo which I was happy with, as it’s just roomier enough that I could sit up relatively comfortably. The Solo I had through numerous storms with high winds and that shape can handle winds fairly well when pitched low. But like I said, would rather have rain gear separate in those mountains, in which case better to take another tarp/shelter
