I built it with long distance self supported road/gravel races in mind. but it would also serve well on remote trips where the 10 ounces of bag weight saved would serve you better as 10 ounces of extra food. i took a prototype of this bag built in the Xpac 70 D fabric on the TDR last year and it held up fine. So maybe it's tougher than i think.
I would add this bag isn't as durable as our regular seat bags. if your touring across Alaska, the D40 or standard bag would serve you better.
