comment How safe is sleeping in a bear country?
In other words, do you say that it’s not really a problem to have a bear close to you in the night, say 50 meters, provided that the food is not where you sleep?

I seldom have the patience :)

comment While backpacking, should one bring hand sanitizer, soap, or both?
The kind of soap I buy is just olive oil with water and some mineral salts. I think the special biodegradable kind is mostly marketing only needed in places where you can’t get plain soap without perfumes and other extras.

comment Tips for outdoor during the dark winter?
Also, there are many good headlamps (Fenix, Zebralight, Princeton Tec) offering several light output levels from dozens of lumens to hundreds. They can last dozens of hours in the lower output modes, so it’s perfectly possible to just use one headlamp and toggle the modes according to need.

comment Winter Camping: How to warm up your boots in the morning?
I find it impossible to warm my feet in the frozen boots until after the first few hundred meters on the track, when the whole body really heats up. But I run in the frozen boots around the camp, too, because what else can I do? :)

comment Winter Camping: How to warm up your boots in the morning?
Plastic bag would be a must, indeed! But even after that I wouldn’t want to share the snugness of my sleeping bag with the… resulting object.

comment How safe is the bowline knot in different situations?
I have edited the question to sound less alarmist. I didn’t want to go to the completely general case of loading different types of knots, but I think you can still slip the information about the figure-8 into your answer quite nicely.

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?

comment Bear spray vs. rifles against polar bears?
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?

comment Do bear-safe rules still apply in the winter?
Why is it misleading? Wikipedia says bears don’t hibernate and the quoted scientific study confirms that. In no part of the answer I imply that bears are not dangerous – if anything, my answer says that you should be careful around bears even in winter.

comment The outdoors, solitude and dealing with loneliness
Europe, and yes, there are no rational reasons to be nervous after sunset, but that doesn’t seem to help :)

comment One-day hike around Prague
Great post! You can camp (or rather bivouac) even in national parks and national preserves, provided that you only stay on one place for one night without a tent and open fire (gas stove is fine). Common sense applies. Here’s the source (Czech only, sorry).

comment Winter food : Should I change my habits for winter?
I’ve learned to push the water in the tube back to the bladder after drinking. During the summer it helps to keep the water from getting warm in the tube, hopefully it will also work in the winter to keep it from freezing.

comment What characteristics should I look for in a good torch/flashlight?
On related front, for Petzl Nao adapts the light power according to where you look. I don’t think it’s designed against blinding other people, but it’s worth mentioning. Also, it’s easier for a headlamp to double as a flashlight than the other way around. But if you insist on getting a flashlight (I understand that), Fenix also makes flashlights that look very nice.

comment How do I reseal a tent bottom with many pinprick holes
This is one of the reasons to buy from a company that offers good service, like replacing the floor for a small fee. Maybe your manufacturer does, too?

comment How much vertical distance is it possible to make in a day?
Great answer, thank you. I’ve added some metric equivalents, hopefully I didn’t mess up.
