My favourite 26 inch tyre is the Schwalbe Hurricane which comes in at 650-690 grams and is a 2.0 but feels like a road tyre at 70 psi... have not used another tyre that is as bulletproof or gotten so many good reviews from people who's bikes have been refitted with these through my shop.
If tyre clearance is not an issue these are an excellent choice and are quite capable if your adventures also take you off the road where they can be run at 35 psi.
I have put well over 10,000 km on a single set of Hurricanes and used them on my touring bike, cargo bikes, and XC mtb and will be riding on them for what will be their 5th season as they do not show any undue wear and still look nearly new.
