I carry my PSK in my Front or Side cargo pocket! If you don't wear similar hiking clothes,You could Alway's stash it in your Calzones!If someone Enquires to the"Bulge",Tell them You are happy to See them! Despite the Good info from the other posts,Isn't it Summertime in Chile?If it is,You'll be more likely to shed everything but the shorts,in this case,Unless...Your destination is Up in The Andes or Tierra del Fuego! Bueno Suerte!
