Rugged
"Rugged" describes something that is strong, durable, and able to withstand harsh conditions. This term is often used to refer to landscapes, such as mountains or coastlines, that are rough and unrefined. It can also apply to products, like outdoor gear or vehicles, designed for tough environments.
In a broader sense, "rugged" can describe a person's character, indicating resilience and toughness. For example, someone who has faced many challenges and continues to persevere might be described as having a rugged spirit. This quality is often admired in both individuals and the products they use.
