@_Dieter in response to your post on the various packs. The best option is really to go into the shop and feel which one sits better on your back. I went to Drifters wanting an Exos, but after fitting it I rather went with the Mutant which is actually a climbing pack. This means it doesnt have suspension but sits flush against the back. Doesnt ventilate as well, but is GREAT for climbing / scrambling / bushwacking. A bit of a weird choice but it worked in the shop and now I am in love. That said, I also have the big cushy pack and nothing beats a good suspension setup for long days and comfort.
If you are starting out - aim for the lightest gear possible, but dont get too caught up in this “fast and light” trend. There is either some kind of sacrifice being made (heat, food, comfort), or the fast and light person is an investment banker and his gear collection is worth more than a small car.
Most of the people punting fast and light are people that have earned it, i.e. they have put in the hard yards and likely know the areas that they travel in like the back of their hand. You can get caught with your pants down if you dont know what you are doing. I have done missions “fastpack” style, but only if I have been on the route before and know exactly what to expect.
Mostly, I way prefer having sufficient warm clothing to actually enjoy being outside at night. For example, on a recent offtrail 7-day hike, the “fast and light” fanboy had a 13kg pack, but he was in his tent by 6pm every day, eating his military food rations in solitude. The rest of us were in the 18-22kg range, and we happily sat outside every night until 9pm, having tea, eating together and enjoying the stars. In line with this, you gauge your preparedness with the rest of the group.
I hope this doesnt get interpreted as a rant, just trying to give some perspective. it is very easy on the internet to get inspired by mountaineers that have earned their keep over many years of mistakes, only to realise that you are in over your head when the shit hits the fan. The shit doesnt hit the fan often but if it does, it can be a sordid display of real and uncontrollable horror that one does not want to repeat.
