Laos is a tropical country. Therefore, take thin cotton clothes. For the evening, a high-necked T-shirt with long sleeves or a thin cotton sweater is handy as protection against mosquitoes. Take note that it is better to take too little rather than too much. Whatever you may miss you can often buy for a small sum. An umbrella is useful, both from the rain and the bright sunlight. A wool sweater or vest (especially in winter) is indispensable, especially in the mountains. Rainwear is useful during the monsoon. A few pairs of good, comfy walking shoes with good tread and a pair of slip on shoes is everything your feet will need. Remember that in the Buddhist shrines of the country one should enter barefoot.
