A: How can you tie a clove hitch one handed? I found several videos showing a one-handed clove-hitch without clipping, as I think you want: https://youtu.be/ostQdhLI9Y?t=200 https://www.youtube.com/watch?v=I8qSoIY6FPc https://www.youtube.com/watch?v=K-4RMnULYIM It looks a little fiddly to me and I'm not sure where this would be needed versu...

A: Techniques for handling pumped arms? (Hopefully this doesn't apply to you but I think it is a needed reference.) Anyone suffering from unusual or extreme "pump" needs to be aware of functional compartment syndrome, also known as chronic exertional compartment syndrome. Excerpts from the book One Move Too Many by Hochholzer and Schoef... (more) |

A: How to train climbing endurance at home? Full body weight hangboard training or pull-ups are way too intense for me to build or maintain route endurance. To extend the time under tension to the length experienced on a route and to practice resting as is needed in route climbing I suggest a modification: chair pull-ups, but using the hangbo... (more) |

A: Can I fall out of my sit harness? You certainly can, if the waist belt isn't high enough and tight enough. A few years ago I briefly worked at a small rock wall where among other duties I belayed and showed people how to put on a harness. In my experience most newcomers don't (want to) fit the waist belt properly, and a significant... (more) |

A: Deodorising rain jacket without ruining waterproofing I recommend you try Gear Aid MiraZyme. It is formulated specifically to remove odors and it is safe for your waterproofing. It does not require you to wash your garmet harshly; instead you dip your garment in a dilute solution and leave it to air dry. (more) |

A: How can I tell a “trail shoe” from a regular sport shoe? As you can see from the existing answers there is no consensus on this. Something may be "a trail shoe" simply because marketing says so. More pragmatically if someone successfully wears a shoe on a trail it is by definition a trail shoe. Presumably, they are different from the ones above, that... (more) |

A: Do tent colors have functional purposes? I have a Marmot tent and those were my color choices. I chose the brighter one as I thought it would be useful if I were lost and needed visibility, either lost from my own campsite or in need of rescue, and because orange seemed more cheerful. I discovered that the light gray and orange fabrics let... (more) |

A: How to get kinks and twists out of a climbing rope? Avoid the problem with a better solution Avoiding the twisting in the first place surely is best, and there is a simple way to do that: This is the Super Munter, Monster Munter, or Double Munter. It is essentially a second Munter tied over the first in the opposite direction, and this symmetry... (more) |

A: What respirator should I get for urbex? I am not an "urban explorer" but in other uses I have never found the simple fiber masks like ShemSeger pictures to seal well enough to be much good. It doesn't matter how good the filter material is if air leaks around the sides. I would only trust something with an actual gasket. How much airbor... (more) |

A: Bouldering beside the freeway I have no special knowledge of this subject but it is my understanding that rock cut by blasting fractures deeply, beyond the part that is removed, and that as a result climbing on such rock is typically not safe as entire blocks are liable to come loose. A bolt is worse than no good if it pulls a b... (more) |

A: What accreditations should a professional rock climbing cams reslinger have? There is a UIAA certification for slings just as is there are for (nearly?) all critical recreational climbing gear. You should only have reslinging done by a company that produces UIAA certified climbing softgoods. Certification logo: http://www.theuiaa.org/uploadarea/Safety/Standards/Safety-S... (more) |

How to safely train for and grip pockets? I was spurred to post this after reading Which fingers to use in a 2 finger pocket when rock climbing? Last year I injured myself training on a shallow three finger pocket with an open hand grip and my pinky dropped. While hanging with maximum effort I felt a popping sensation in the palm of my h...

A: Why are eye friction hitches not commonly used in rock climbing? Something that occurred to me after asking is that a Prusik is bidirectional, whereas generally the arborist's knots are unidirectional. I believe the unidirectional knots are easier to both slide up and release, making them superior in a dedicated climbing rig, but their application is limited as w... (more) |

A: What is the difference between "dry rope", "non-dry rope" and "dry core rope"? This question has already been well answered but I would like to address a slightly different point: What's the problem with a wet rope anyway? Dynamic climbing ropes are, to the best of my knowledge, universally manufactured from Nylon 6 or Nylon 6,6. Nylon is a somewhat unusual polymer in that i... (more) |

Why are eye friction hitches not commonly used in rock climbing? It seems that the majority of professional arborists favor friction hitches that are tied with a free cord rather than a loop: Blake's Hitch Schwabisch Distel Valdotain Tresse This is often tied using an eye to eye hitch cord like this: This is a Blake's hitch: One can also tie an asymmetri...

A: Is it ever necessary to double up locking carabiners? A number of prominent climbing organizations (e.g. International Federation of Sport Climbing) either recommend or require two locking carabiners for clip-in attachment to a harness, e.g. IFSC Rules 2015 [1MB DOC] 8.3.5 The climbing rope shall be connected to the competitor's harness by two Scr...

A: How to take care of climbing hands? For the most important kind of care of your hands please read: Can a Finger Pulley injury be predicted / anticipated?

A: What is a "shooting jacket"? According to: Competition Shooting 101: CMP/NRA High Power By Nick Leghorn on April 21, 2011 Shooting Jacket – This is another tool for keeping you steady.

A: Permanent Camping Cooler - No Ice Needed Although technology has brought us many conveniences most of them require supporting power or other technology. You seem set on refrigeration and you say: "I am willing to go to just about any extent short of buying a fridge and a generator." Perhaps you should consider solar panels (photovoltaic) ... (more) |

A: What are creative uses for retired carabiners? This is probably going to be an unpopular opinion because it's not nearly as "feel good" as helping remote Asian herdsmen. (Which incidentally is probably one of few exceptions to what follows.) Nevertheless: It is my belief that unsafe carabiners should be destroyed. In my opinion it is too grea... (more) |

A: What rope to chose to hold my body weight from a monkey fist knot As Ben Crowell already noted you are not going to be taxing a rope very much in this application, and unless you are planning acrobatic moves off of these holds (which you very well may be) there is little danger even if the rope (or cord) fails. Unless you happen to get a very good deal even 6mm ac... (more) |

A: How high to climb before clipping on a sport climb? The pragmatic answer has already been given, but in my own words: Clip from the most solid stance available Clip with your harness as close to the rope-end carabiner as possible Sometimes the old mantra "the leader must not fall" still applies There is a "trick" I'll share at the end of this post...

A: How do you stop blood-flow from a leech bite? I have heard that if you do not remove the leech until it gets full and naturally drops off that you will not bleed much, and that it is safer because you reduce the risk of infection. At the moment I can't find good sources for this, only: How to Remove a Leech (Go Borneo Travel. Com): In cas... (more) |

A: "Used" top rope when bouldering With due respect to Ben Crowell, who is I believe a far more experienced outdoorsman than I am, I beg to differ with his answer. (Edit: his answer prior to revision.) Having worked at a very small climbing wall I have seen tough ropes completely worn out by top-rope climbing alone, therefore at lea... (more) |

A: What are the benefits of Vibram FiveFingers? Ben Crowell already answered the "why minimalist" angle better than I could have, but he didn't specifically talk about Vibram FiveFingers (hereafter VFF). This is intended to complement his answer.

A: When should I retire my rope The manufacturer of your rope says: Time in use : The potential lifetime of BEAL PPE in use is up to a maximum of 10 years.

A: Can a Finger Pulley injury be predicted / anticipated? Rather than try to answer the personal part of your question, which as Liam said needs a doctor's attention to answer properly, I shall reply to the more general title: Can a Finger Pulley injury be predicted / anticipated?

A: Is it realistic to teach yourself rock climbing? With dedication you could learn to climb at a top-rope or bouldering climbing gym without professional instruction. The key skill there is belaying, and you could learn that from videos. However I would never recommend this route if good instruction is available. You may have difficulty separating... (more) |

A: What's the minimum diameter cord to use when climbing a rope using a prusik I am going to approach this question differently. Since the question is marked with the rock-climbing tag the use of a 7.5mm Technora escape rope that AMHawk's answer focuses on seems unlikely. Also, the method by which he arrives at a minimum Prusik cord size doesn't address certain issues. Cord ... (more) |

A: How to clean rock-climbing shoes? A UV-C germicidal light kills the odor-producing bacteria, so used regularly the smelly compounds never build up and your shoes don't stink. It also helps to dry your shoes after use, e.g. in front of a fan. And, as stevemarvell said, wash your feet before you climb. I assembled my own UV-C steril... (more) |

A: Abandoning a multi pitch climb You leave behind gear sufficient to create a rappel anchor that is strong enough for any conceivable load that may be placed upon it.

A: Sunblock for clothing-optional camping I can't help but think that this question may trolling, but here goes anyway.

A: Who places the anchors that rock climbers use? As far as I know there are no general authorities for the placement of fixed gear and bolts may have been placed well or poorly.

A: Best type of rope for glacier travel? Beal Ropes has a guide that covers this.

A: For what it's worth: climbing-tape I have only used Metolius tape myself but this blog post makes the claim: With tape, stickiness is crucial.
