Can I leave my tent in a storm?
A tent can always be damaged by excessive external weather conditions. We do not provide any warranty for this. A tent should be kept closed in windy conditions - the walls act as stabilizers, similar to cross-braces - and in stronger winds or storms, we always recommend dismantling the tent. Unfortunately, we cannot provide specific wind speed information as this depends on several factors such as location, anchoring, condition, etc.
