Okay, the user wants me to translate "ski-hats" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule mentions if the content is already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "ski-hats" is in English. I need to translate it. The direct translation would be "หมวกสกี" because "ski" is สกี and "hats" is หมวก. But I should make sure if there's a common term in Thai for ski hats. Maybe "หมวกกันหนาวสำหรับสกี" but that's more descriptive. However, the user probably wants a direct translation. Let me confirm. The user might be looking for a simple translation rather than a descriptive phrase. So "หมวกสกี" is the most straightforward. I'll go with that. No explanations, just the translation.
