I am hiking the Kalalau Trail in Kauai the last week of August and this will be our first backpacking trip that we will be hanging. I am curious if anyone has any recommendation for how much insulation we will need. The average low there is 75 during that time of year. I was considering just taking sleep sheets, but I just have not slept in the hammock in temperatures cooler than 80 and I am curious if it will get cool if it gets below 75. Any suggestions would be appreciated. Thanks.
