comment How safe is the bowline knot in different situations?
@DavidR, you’re right, but the problem is that the bowline is often presented as a knot that can’t slip no matter what. And unstated non-obvious assumptions (such as that you don’t load the knot sideways) are very bad when talking about safety. Even in my answer I say that the first option is perfectly acceptable and further discussion here should make the case completely clear. Main thing is that people know the dangerous case.

comment What are good knots to know for camping and backpacking?
Bowline absolutely and positively can slip, even under load, people have died because of it. The problem is in the way you put load on the knot. If you load the main part of the rope going away from the knot, everything is fine. But if you pull the main “loop” sideways, for example by creating a sling around a tree and rappelling down from the sling, the knot can untie easily, especially if the force comes and goes. I will explain further in a follow-up question.

comment Bear spray vs. rifles against polar bears?
Even if the chance of shooting the bear is small (I have no idea), it’s still better than just standing there and realizing that the noise flare didn’t work out? Or did you mean to say that you would go for a noise flare + pepper spray combination?

Better title.

The obvious downside to a noise flare in comparison with a big gun is that when the first attempt at scaring the bear is not successfull, with a rifle you still have a chance?

comment Do bag liners add the same warmth value to all sleeping bags?
What’s its weight? Unless it’s several hundred grams I doubt the insulation value. 15 degrees of difference is a lot.

comment What is a typical elongation of a dynamic climbing rope?
I don’t think you can go wrong with any UIAA-certified climbing rope, can you?
