I'm new to EpicSki, but have been doing cross country skiing on and off my whole life (originally from the northeast). I'm putting together a hydration pack for the upcoming winter so I can do some longer day treks in the Washington/Idaho area, and am looking for some general advice on what to bring with me in my backpack (I searched, but most results were related to downhill, or were from years ago, so I'm putting it out again for new opinions).
I'm basing it out of a 2L hydration backpack, and already have the typical tools and safety gear (flashlight, first aid kit/sunscreen/lip balm, multi-tool, thermal blankets, glowstick, fire starters, paracord, compass, signal mirror).
My question for you all then is - what item or items would you not go into the woods without? Any stories to prove a point are welcome :)
