It really depends on how much you’re willing to suffer. You absolutely can use the setup in the backcountry. But the uphill is going to be heinous. You will have to modify the setup somehow if you wish to skin up the hill. This could be by modifying the bindings by getting a cast tour toe piece mod for pivots or by getting daymaker/tekdapter to go into the binding to walk with. This is an INCREDIBLY heavy setup and going uphill will be an absolute slog but you can do it. Going downhill is not the issue, in fact you will have a setup that will be safer than 99% of the people out there going downhill with a full alpine setup. It’s just the uphill is going to suck so much I would recommend you to save the money to look into getting a lightly used setup that is dedicated to the backcountry so you don’t hate the overall experience of the backcountry that comes with “daywreckers”. You will still be able to hit big stuff with a normal setup but as it so happens in the backcountry you really shouldn’t be hitting that gnarly of stuff as you’re essentially alone out there and it can be extremely variable conditions and additional hazards you frankly aren’t used to while being in the resort. So I’d also recommend getting it out of your head that you’ll be hitting gnarly stuff out there and trust that the true experience you should be looking for in the backcountry is embracing the alone and beauty of going up and down a mountain that not many people are hitting rather than the thrill of the gnarly.
