Yes, and that's it!
On top in the ruck sack comes the Snug Pack Special Forces 1 Sleeping Bag (1030g) in the Snug pack Special Forces bivvy bag (340g) in the Snug Pack Dry Sack M 8 Litres (60g).
In my ruck sack you can see the foldable german army insulation mat (425g).
I recommend the Defcon Poncho in the Vegetato Italiano camouflage (400g) as a small tarp and rain cover in summer times.
That is original Nato stuff.
Decathlon 2 mm Simond line, 10 meters for the Poncho, 10 meters as a washing line (2x20g).
How to deal with it I explained in the thread "Wild Camping".
If you have to deal with hard ground, take 4 orange Decathlon aluminium pegs (4x9g)together with the lines in a bright small bag, and put this in your poncho bag!
May be a mosquito head net (30g) would be a good idea.
May be the little back up lamp Photon micro light could be useful (5g).
And that is all I need down till 0*C for trekking tours of several weeks.
LESS IS MORE !
What I am usually wearing on the body you can find in the List in the beginning with the Decathlon equipment.
Here it is important to understand, that my shirt is large enough to wear it OVER the Fleece jacket if I need it as a wind stopper jacket.
Have a look for "Pinewood Sahara" Zipp Off Trousers, if you want them in olive green.
The swimming shorts replace them if they are drying on the washing line, if it is cold, I use instead of them the rain trousers, when they are drying.
So, Ladies and Gentlemen!
Just try it out!
