Weather in Yellowstone is unpredictable and you should plan for every eventuality – heat, sunshine, cold, rain, and snow – regardless of the time of year. If you are adequately equipped with the right gear and clothing, you are more likely to have a safe and comfortable experience.
In general, it is best to bring multiple layers of clothing constructed of wicking fabrics (synthetic or wool) that draw moisture away from the body. Layering will allow you to closely regulate your body temperature in response to changes in weather and your activity level.
Required clothing varies by season (see the winter clothing list and summer clothing list) and, to some degree, by course. Please read the clothing/equipment list that applies to your seminar and pack accordingly.
