For around 40 Days hiking, 25-30km per day, backpack weight around 12kg, is waypoint 35 ok for this trip? Also do you thing waypoint is ok for carry on luggage on fly?Thank you so much.
I guess you will be approached by Japanese airlines when you bring in your luggage with the amount you have. The weight is bearable, so you might want to think carefully about whether it fits your packing style.
