What attire works best for off-road nature excursions?

The provided comments do not directly address appropriate attire for off-road nature excursions in Aruba. Instead, travelers discuss transportation options and dining recommendations. Several visitors mention renting vehicles or booking tours to explore the national park, caves, natural pools, and other outdoor sites, but none specify clothing or gear suitable for rugged terrain.

For context, those who explored independently via rented jeep reported visiting viewpoints, chapels, and wildlife sanctuaries, while others preferred guided safari tours for accessing natural features. One traveler emphasized bringing snorkeling gear for coastal areas. However, without explicit guidance on footwear, sun protection, or fabric choices for off-road conditions, the comments leave this question largely unanswered.
