I am looking at getting into cross country skiing. I live in Alaska and am looking to get out into the woods more during winter. I have some outdoors experience from thru hiking and hunting but when it comes to skis I am a complete beginner. I have downhill skid a couple of times years ago so I know the bare bones basics of the pizza and french fries and thats about it. Cross country seems a bit more practical for exploring around my area, riding a lift and going down the same hill over and over again doesnt really do it for me.

I dont want to spend a ton of money especially since I dont know what to look for in equipment, I am considering picking up some gear off facebook marketplace. I have some nice hiking trekking poles which I assume would be fine to use?

Can somebody point me in the right direction towards a beginners guide or some good youtube videos to get me started? I am trying to figure out what gear I need, what size/length skis (I am 193cm) and what shoes might be compatible with what skis etc etc
Also do I really need to wear those tight ass queer pants?
