Stealth Adirondacks hiking

Hey all, ill be going on a two day hiking trip with cis guy friends that don't know i am trans in a few weeks in the Adirondacks. It will be my first time going there so i am unaware of the installations but i assumed there would be no toilets along the trails and bought myself my very first STP (the lou from TGsupply) with the stp pouch from mypack. Now, is this going to hold up great in 20km long hikes? I am stressed because these are a lot of firsts coming up, any advice is welcome.
