Nepal is somewhat conservative when it comes to clothing. While the majority of the populace are Hindus and Buddhists, the Nepalese society prohibits nudity and unnecessary body exposure. We advise the tourists visiting the country to be wary of such customs and have the courtesy to respect the existing social values.
Now, onto the clothing necessary for the trips, you can be light cotton clothes during the summer season. Thick jackets, trousers, and comfortable warm boots are a compulsion during the winter season. The clothing also varies as per the trips you undertake. Tours and hikes can be done with casual clothing; however, hiking requires slightly more attention. Treks and expeditions must be done after all the necessary supplies including clothing have been taken into account with great care.
