Just finished a five day hike in western Canada. Temps hit about 45F at night, and we all froze miserably. We used Walmart type of sleeping bags and they were worthless. Had to wear every shirt and pants to bed and still shook all night. NEVER CHEAPOUT ON SLEEPING BAGS. And then, I tried to use my nine dollar Walmart fire steel rod, and the damn thing broke its handle off and then the rod itself cracked in half. Between the crappy sleeping bags and useless fire steel, this scenario could be fatal I there weren't other supplies available. If you buy cheap gear you may die because of it. Your life may come down to the smallest item so buy the best quality.

One hiker packed what is called a freezer coat. Usually they are black colored, quilted coats used by warehouse workers and truck drivers kind of thing. Definitely not the kind of clothing you would associate with hiking. However, the coat is super light, rolls up really small and is very warm. And cost is only about thirty bucks and you can get them is a few other colors like green or brown or grey. I will never hike or camp again without one.

ALWAYS TAKE SOME EXTRA CLOTHES BECAUSE IT CAN GET VERY COLD AT NIGHT UNEXPECTEDLY AND WEATHER FORECASTERS ARE FULL OF SHIT.
