Then the Norrona Reconpack would do you admirably. But as the others have said in the thread, why would you want to carry so much. Even multiday winter hikes shouldn't weigh more than 15-20Kg with modern equipment. Summer multiday hikes shouldn't be over 12-15Kg in weight. Lightweight Hikers can get down to 10Kg and still have a very comfortable camp.

As the Reconpack has a huge 125 Litre capacity, the temptation to pack in everything creates its own problems. In general for winter use you should be able to get everything you need in a 65-75 litre pack and in the summer a 45-50 litre pack should suffice. The Norrona pack itself weighs 4.7Kg and with the 40Kg capacity this makes 44.7Kg (98.4 lbs). With this load I would be surprised if you were able to cover more than a few miles in a day in difficult terrain.

it may be a better compromise as it may be a bit more flexible in use.
