My wife and I are going to jackson in mid april and we are buing some outerwear for winter and our trip. We will be going on some day hikes <4mi(so no longer than 5hrs)but we will be staying in jackson at night. I am tring to figure out what outerwear to get. We alredy have some decent fleece jackets(mtn hardware and cloudveil), but we are looking into shells/down/wind fleece. We will either buy a shell to go over our current fleece or buy wind fleece and down jackets. I dont know what route to go as I am not sure what temp the mountains are that time of year. Also any other info on jackson would be great. We are staying at inn on the creek and renting a car to go to yellowstone and the tetons.
