New Lifes or Live Lifes would be a bit more practical with Dukes. I'd go with Live Lifes for a backcountry set up.
I bought all my gear this summer for a BC set up, trekkers, skins everything. The skins were fitted to the Green Lifes that I had bought, sadly I had to sell them to pay for boots.
So I'll have to rig up those skins somehow to fit my One Lifes. It'll look weird I tell you.
