I have the adventure suit, my son and brother in law have the badlands.
The badlands is by far and away better and if it had been out when I bought mine I would have had the badlands.
We did a two week trip last year which was a disaster weather wise, it rained non stop for the whole trip, jacket and strides completely waterproof, by the end of the trip my other brother in law, was looking to buy a klim suit and replace his rukka, every time we stopped by the time we went in for a coffee we were drip dry on the outside, where as his suit whilst waterproof was sodden with water and dripped for hours.
The built in armour in the Badlands is better it has a chest pad as well as back, it also has more usefull pockets on the inside.
The only advantage of the adventure jacket is that its a little better vent wise in hot weather as there is less on the inside of the jacket, it can be worn with a neck brace it also has enormous pockets on the back so that you can carry all your essential kit with you, which would be good on a long distance trip, and it is a tougher outer material, but in all other respects the Badlands is better, particulary in a cold wet climate.
I would say that it is probably the best suit that any money can buy at the moment.
I cant personaly comment on the Badlands but if I have an issue with Klim stuff its that their sizing is crap, I had two pairs of gloves marked as the same size, yet one pair was significantly smaller than the other, so now have one xxl pair one xxxl pair? my son had same problem with the suit, needed a size larger in the strides than the jacket, I have the biggest size in available ;-), but the sleeves and cuffs are tighter than they ought to be for the size of the rest of the jacket, its still the best kit I have ever owned though, being able to go out in the worst weather and know that I will be warm and dry at the end is a great feeling.
Its well worth trying them on first given how much your spending.
