Summit the week of the July 20th.
Is a down jacket needed for summit or camping at 10k' the night before? I have a wind/rain shell that I layer with poly fleece and performance shirt. Worked well for me on similar hikes. The weather forecast looks great for temp and wind with no storms.
As for water, plan to take 3L water bladder with a Gatorade bottle or 2. Water pump and filtering/treatment still recommended for this setup, or just grab some snow and use a few tabs to treat it? Rather not sit and pump for awhile.
