Hello - A party of three of us have a two day permit for this weekend. We plan on camping at Whitney portal this Friday and Saturday night leaving Sunday and summiting Monday and returning Mon night. I plan on going as light as possibe. I have a camel bak trail blazer with a 70 oz water bladder emergency supplies and food. I also have a fanny pack with two 18 oz water bottles and storage for other stuff. Inside my pack I have a one man tent.
The question I have is could I get away without carrying a sleeping bag. Just a sleeping pad to put underneath me and climbing into a bivy inside my tent ? If not, I will have to rent a larger backpack at REI. How cold at night does it get at trailcamp ?
