Cotton is NOT King in Panama! We recommend light fishing style clothes, polyester, nylon etc dry fast stuff. Normal kayaking cover up gear for offshore and casual shorts, shirts and flip flops on shore. We won’t send you anywhere you can’t go in shorts and flip flops unless you plan to spend several extra days in the city. We have laundry service available at least once during your stay so pack light. If you plan to hike or horseback ride a pair of lightweight long pants and light boots/hiking shoes are recommended. Also water shoes for reef walks and the beaches, our volcanic dark sand gets hot.
